Question: Information:  - The Federal City of Bonn is a city on the banks of the Rhine in the German state of North Rhine-Westphalia, with a population of 311,287. Bonn is in the southernmost part of the Rhine-Ruhr region, Germany's largest metropolitan area, with over 11 million inhabitants.  - The Saarland (German: "das Saarland"  ; - ) is one of the sixteen federal states (or "Bundesländer") of Germany. With its capital at Saarbrücken, it has an area of 2,570 km² and its population (as of 30 April 2012) is approximately 1,012,000. In terms of both area and population size  apart from the city-states of Berlin, Bremen and Hamburg  it is Germany's smallest federal state. The wealth of its coal deposits and their large-scale industrial exploitation, coupled with its location on the border between France and Germany, have given the Saarland a unique history in modern times.  - Hamburg (local pronunciation ; Low German/Low Saxon: "Hamborg" ), officially "Freie und Hansestadt Hamburg" (Free and Hanseatic City of Hamburg), is the second largest city in Germany and the eighth largest city in the European Union. It is the second smallest German state by area. Its population is over 1.7 million people, and the wider Hamburg Metropolitan Region covers more than 5.1 million inhabitants. The city is situated on the river Elbe.  - France, officially the French Republic, is a country with territory in western Europe and several overseas regions and territories. The European, or metropolitan, area of France extends from the Mediterranean Sea to the English Channel and the North Sea, and from the Rhine to the Atlantic Ocean. Overseas France include French Guiana on the South American continent and several island territories in the Atlantic, Pacific and Indian oceans. France spans and had a total population of almost 67 million people as of January 2017. It is a unitary semi-presidential republic with the capital in Paris, the country's largest city and main cultural and commercial centre. Other major urban centres include Marseille, Lyon, Lille, Nice, Toulouse and Bordeaux.  - The Saar Protectorate ( German : Saarprotektorat ; French : Protectorat de Sarre ) was a short - lived protectorate ( 1947 -- 56 ) partitioned from Germany after its defeat in World War II ; it was administered by the French Fourth Republic . On rejoining West Germany in 1957 , becoming the smallest `` area state '' ( Flächenland ) , the Saarland , not counting the `` city states '' ( Stadtstaaten ) of Berlin , Hamburg and Bremen . It is named after the Saar River . The region around the Saar River and its tributary valleys is a geographically folded , mineral - rich , ethnically German , economically important , heavily industrialized area . It has well - developed transportation infrastructure that was one of the centres of the Industrial Revolution in Germany and around 1900 formed the third - largest area of coal , iron , and steel industry in Germany ( after the Ruhr Area and the Upper Silesian Coal Basin ) . From 1920 to 1935 , as a result of World War I , the region was under the control of the League of Nations as the Territory of the Saar Basin . Near the end of World War II it was heavily bombed by the Allies as part of their strategic bombing campaigns . Geographically , the post -- World War II protectorate corresponded to the current German state of Saarland ( established after its incorporation into West Germany on 1 January 1957 ) . A policy of industrial disarmament and dispersal of industrial workers was officially pursued by the Allies after the war until 1951 and the region was made a protectorate under French control in 1947 . Cold War pressures for a stronger Germany allowed renewed industrialization , and the French returned control of the region to the government of the Federal Republic of Germany in 1957 .  - The United States dropped nuclear weapons on the Japanese cities of Hiroshima and Nagasaki on August 6 and 9, 1945, respectively, during the final stage of World War II. The United States had dropped the bombs with the consent of the United Kingdom as outlined in the Quebec Agreement. The two bombings, which killed at least 129,000 people, remain the only use of nuclear weapons for warfare in history.  - East Berlin existed between 1949 and 1990 and consisted of the Soviet sector of Berlin established in 1945. The American, British, and French sectors became West Berlin, strongly associated with West Germany, while East Berlin was the "de facto" capital of East Germany. From 13 August 1961 until 9 November 1989, East Berlin was separated from West Berlin by the Berlin Wall.  - West Berlin was a city that existed in the period between the end of the Berlin Blockade on 12 May 1949 to German reunification on 3 October 1990 as a political enclave surrounded by East Berlin and East Germany. It was east of the Inner German border and only accessible by land from West Germany by narrow rail and highway corridors. It consisted of the American, British, and French occupation sectors established in 1945 and shared economic, political, legal, and sporting systems with West Germany, but was not "de jure" part of it. It had a special and unique legal status because its administration was formally conducted by the Western Allies. East Berlin, "de jure" occupied and administered by the Soviet Union, was the "de facto" capital of East Germany. The Berlin Wall, built in 1961, physically divided East and West Berlin until it fell in 1989.  - The Warsaw Pact, formally the Treaty of Friendship, Co-operation, and Mutual Assistance and sometimes, informally, WarPac. was a collective defense treaty among the Soviet Union and seven other Soviet satellite states in Central and Eastern Europe in existence during the Cold War. The Warsaw Pact was the military complement to the Council for Mutual Economic Assistance (CoMEcon), the regional economic organization for the communist states of Central and Eastern Europe. The Warsaw Pact was created in reaction to the integration of West Germany into NATO in 1955 per the London and Paris Conferences of 1954, but it is also considered to have been motivated by Soviet desires to maintain control over military forces in Central and Eastern Europe.  - During World War II, the American atomic bombings of Hiroshima and Nagasaki made Nagasaki the second and, to date, last city in the world to experience a nuclear attack.  - The German reunification was the process in 1990 in which the German Democratic Republic (GDR/East Germany) joined the Federal Republic of Germany (FRG/West Germany) to form the reunited nation of Germany, and when Berlin reunited into a single city, as provided by its then Grundgesetz constitution Article 23. The end of the unification process is officially referred to as German unity, celebrated on 3 October (German Unity Day). Following German reunification, Berlin was once again designated as the capital of united Germany.  - In general, a civilian is "a person who is not a member of the military or of a police or firefighting force", as defined by Merriam Webster's Dictionary. From the perspective of the U.S. Department of Defense, Chapter 18 of Title 10 United States Code refers to non-military law enforcement officers as civilians since they are employees rather than enlisted personnel, and also in order to distinguish itself from military police. In military and law enforcement slang, the term "Civies" or "Civvies" are often used to refer civilian population or civilian clothing.  - Trench warfare is a type of land warfare using occupied fighting lines consisting largely of trenches, in which troops are significantly protected from the enemy's small arms fire and are substantially sheltered from artillery. The most famous use of trench warfare is the Western Front in World War I. It has become a byword for stalemate, attrition, sieges and futility in conflict.  - A city-state is a sovereign state that consists of a city and its dependent territories. Historically, this included cities such as Rome, Athens, Carthage, and the Italian city-states during the Renaissancebut today only a handful of sovereign city-states exist, with some disagreement as to which are city-states. A great deal of consensus exists that the term properly applies to Singapore, Monaco, and Vatican City.  - A protectorate, in its inception adopted by modern international law, is a dependent territory that has been granted local autonomy and some independence while still retaining the suzerainty of a greater sovereign state. In exchange for this, the protectorate usually accepts specified obligations, which may vary greatly, depending on the real nature of their relationship. Therefore, a protectorate remains an autonomous part of a sovereign state. They are different from colonies as they have local rulers and people ruling over the territory and experience rare cases of immigration of settlers from the country it has suzerainty of. However, a state which remains under the protection of another state but still retains independence is known as a protected state and is different from protectorates.  - Weimar Republic is an unofficial, historical designation for the German state between 1919 and 1933. The name derives from the city of Weimar, where its constitutional assembly first took place. The official name of the state was still "Deutsches Reich"; it had remained unchanged since 1871. In English the country was usually known simply as Germany. A national assembly was convened in Weimar, where a new constitution for the "Deutsches Reich" was written, and adopted on 11 August 1919. In its fourteen years, the Weimar Republic faced numerous problems, including hyperinflation, political extremism (with paramilitaries  both left- and right-wing); and contentious relationships with the victors of the First World War. The people of Germany blamed the Weimar Republic rather than their wartime leaders for the country's defeat and for the humiliating terms of the Treaty of Versailles. However, the Weimar Republic government successfully reformed the currency, unified tax policies, and organized the railway system. Weimar Germany eliminated most of the requirements of the Treaty of Versailles; it never completely met its disarmament requirements, and eventually paid only a small portion of the war reparations (by twice restructuring its debt through the Dawes Plan and the Young Plan). Under the Locarno Treaties, Germany accepted the western borders of the republic, but continued to dispute the Eastern border.  - Military personnel are members of the armed forces. Usually, personnel are divided into military branches roughly defined by certain circumstances of their deployment. Those who serve in a typical large land force are soldiers, making up an army. Those who serve in seagoing forces are seamen or sailors, and their branch is a navy or coast guard . Marines serve in a marine corps. In the 20th century, the development of powered flight aircraft prompted the development of air forces, serviced by airmen. Designated leaders of military personnel are officers. These include commissioned officers, warrant officers and non-commissioned officers (NCOs). For naval forces, non-commissioned officers are referred to as petty officers (POs). military personnel are instructed to wear dog tags  - International law is the set of rules generally regarded and accepted as binding in relations between states and between nations. It serves as a framework for the practice of stable and organized international relations. International law differs from state-based legal systems in that it is primarily applicable to countries rather than to private citizens. National law may become international law when treaties delegate national jurisdiction to supranational tribunals such as the European Court of Human Rights or the International Criminal Court. Treaties such as the Geneva Conventions may require national law to conform to respective parts.  - The French Fourth Republic was the republican government of France between 1946 and 1958, governed by the fourth republican constitution. It was in many ways a revival of the Third Republic, which was in place before World War II, and suffered many of the same problems. France adopted the constitution of the Fourth Republic on 13 October 1946.  - The Elbe (; Low German: "Elv") is one of the major rivers of Central Europe. It rises in the Krkonoše Mountains of the northern Czech Republic before traversing much of Bohemia (Czech Republic), then Germany and flowing into the North Sea at Cuxhaven, northwest of Hamburg. Its total length is .  - Brandenburg (Lower Sorbian: "Bramborska") is one of the sixteen federated states of Germany. It lies in the northeast of the country covering an area of 29,478 square kilometers and has 2.48 million inhabitants. The capital and largest city is Potsdam. Brandenburg surrounds but does not include the national capital and city-state Berlin forming a metropolitan area.  - World War II (often abbreviated to WWII or WW2), also known as the Second World War, was a global war that lasted from 1939 to 1945, although related conflicts began earlier. It involved the vast majority of the world's nationsincluding all of the great powerseventually forming two opposing military alliances: the Allies and the Axis. It was the most widespread war in history, and directly involved more than 100 million people from over 30 countries. In a state of "total war", the major participants threw their entire economic, industrial, and scientific capabilities behind the war effort, erasing the distinction between civilian and military resources. Marked by mass deaths of civilians, including the Holocaust (in which approximately 11 million people were killed) and the strategic bombing of industrial and population centres (in which approximately one million were killed, and which included the atomic bombings of Hiroshima and Nagasaki), it resulted in an estimated 50 million to 85 million fatalities. These made World War II the deadliest conflict in human history.  - Hiroshima is perhaps best known as the first city in history to be targeted by a nuclear weapon when the United States Army Air Forces (USAAF) dropped an atomic bomb on the city (and later on Nagasaki) at 8:15 a.m. on August 6, 1945, near the end of World War II.  - The Metropolregion Hamburg (German for Hamburg Metropolitan Region) is the compilation of eight districts in the German federal state of Lower Saxony, six districts in Schleswig-Holstein, two districts in Mecklenburg-Vorpommern and the city-state of Hamburg in northern Germany. It covers an area of ca , and is home to more than 5.1 million inhabitants.  - World War I (WWI or WW1), also known as the First World War, or the Great War, was a global war originating in Europe that lasted from 28 July 1914 to 11 November 1918. More than 70 million military personnel, including 60 million Europeans, were mobilised in one of the largest wars in history. Over nine million combatants and seven million civilians died as a result of the war (including the victims of a number of genocides), a casualty rate exacerbated by the belligerents' technological and industrial sophistication, and the tactical stalemate caused by gruelling trench warfare. It was one of the deadliest conflicts in history, and paved the way for major political changes, including revolutions in many of the nations involved.  - Saarbrücken ([], Rhine Franconian: "Saarbrigge" []) is the capital and largest city of the state of Saarland, Germany. Saarbrücken is Saarland's administrative, commercial and cultural centre. The city is situated next to the French border at the heart of the metropolitan area of Saarland.  - West Germany is the common English name for the Federal Republic of Germany or FRG (or "RFA") in the period between its creation on 23 May 1949 to German reunification on 3 October 1990. During this Cold War era, NATO-aligned West Germany and Warsaw Pact-aligned East Germany were divided by the Inner German border. After 1961 West Berlin was physically separated from East Berlin as well as from East Germany by the Berlin Wall. This situation ended when East Germany was dissolved and its five states joined the ten states of the Federal Republic of Germany along with the reunified city-state of Berlin. With the reunification of West and East Germany, the Federal Republic of Germany, enlarged now to sixteen states, became known simply as "Germany". This period is also referred to as the Bonn Republic ("Bonner Republik") by historians, alluding to the interwar Weimar Republic and the post-reunification Berlin Republic.  - Germany, officially the Federal Republic of Germany, is a federal parliamentary republic in central-western Europe. It includes 16 constituent states, covers an area of , and has a largely temperate seasonal climate. With about 82 million inhabitants, Germany is the most populous member state of the European Union. After the United States, it is the second most popular immigration destination in the world. Germany's capital and largest metropolis is Berlin. Other major cities include Hamburg, Munich, Cologne, Frankfurt, Stuttgart and Düsseldorf.  - The North Atlantic Treaty Organization (NATO  '), also called the North Atlantic Alliance, is an intergovernmental military alliance based on the North Atlantic Treaty which was signed on 4 April 1949. The organization constitutes a system of collective defence whereby its member states agree to mutual defence in response to an attack by any external party. Three NATO members are permanent members of the United Nations Security Council with the power to veto and are officially nuclear-weapon states: the United States, France and the United Kingdom. NATO's headquarters are located in Haren, Brussels, Belgium, where the Supreme Allied Commander also resides. Belgium is one of the 28 member states across North America and Europe, the newest of which, Albania and Croatia, joined in April 2009. An additional 22 countries participate in NATO's Partnership for Peace program, with 15 other countries involved in institutionalized dialogue programmes. The combined military spending of all NATO members constitutes over 70% of the global total. Members' defence spending is supposed to amount to 2% of GDP.  - The Havel is a river in north-eastern Germany, flowing through the German states of Mecklenburg-Vorpommern, Brandenburg, Berlin and Saxony-Anhalt. It is a right tributary of the Elbe river and long. However, the direct distance from its source to its mouth is only .  - The Spree is a river that flows through the Saxony, Brandenburg and Berlin states of Germany, and in the Ústí nad Labem region of the Czech Republic. Approximately in length, it is a left bank tributary of the River Havel, which itself flows into the Elbe and then the North Sea. It is the river on which the original centre of Berlin was built.  - Berlin is the capital and the largest city of Germany as well as one of its constituent 16 states. With a population of approximately 3.5 million people, Berlin is the second most populous city proper and the seventh most populous urban area in the European Union. Located in northeastern Germany on the banks of rivers Spree and Havel, it is the centre of the Berlin-Brandenburg Metropolitan Region, which has about 6 million residents from more than 180 nations. Due to its location in the European Plain, Berlin is influenced by a temperate seasonal climate. Around one-third of the city's area is composed of forests, parks, gardens, rivers and lakes.  - The European Union (EU) is a political and economic union of member states that are located primarily in Europe. It has an area of , and an estimated population of over 510 million. The EU has developed an internal single market through a standardised system of laws that apply in all member states. EU policies aim to ensure the free movement of people, goods, services, and capital within the internal market, enact legislation in justice and home affairs, and maintain common policies on trade, agriculture, fisheries, and regional development. Within the Schengen Area, passport controls have been abolished. A monetary union was established in 1999 and came into full force in 2002, and is composed of 19 EU member states which use the euro currency.  - The Berlin Wall was a barrier that divided Berlin from 1961 to 1989. Constructed by the German Democratic Republic (GDR, East Germany), starting on 13 August 1961, the Wall completely cut off (by land) West Berlin from surrounding East Germany and from East Berlin until government officials opened it in November 1989. Its demolition officially began on 13 June 1990 and was completed in 1992. The barrier included guard towers placed along large concrete walls, which circumscribed a wide area (later known as the "death strip") that contained anti-vehicle trenches, "fakir beds" and other defenses. The Eastern Bloc claimed that the Wall was erected to protect its population from fascist elements conspiring to prevent the "will of the people" in building a socialist state in East Germany. In practice, the Wall served to prevent the massive emigration and defection that had marked East Germany and the communist Eastern Bloc during the post-World War II period.  - The inner German border (or "deutsch-deutsche Grenze"; initially also "Zonengrenze") was the border between the German Democratic Republic (GDR, East Germany) and the Federal Republic of Germany (FRG, West Germany) from 1949 to 1990. Not including the similar but physically separate Berlin Wall, the border was long and ran from the Baltic Sea to Czechoslovakia.  - East Germany, formally the German Democratic Republic or GDR, was an Eastern Bloc state during the Cold War period. From 1949 to 1990, it administered the region of Germany that was occupied by Soviet forces at the end of World War IIthe Soviet Occupation Zone of the Potsdam Agreement, bounded on the east by the OderNeisse line. The Soviet zone surrounded West Berlin, but did not include it; as a result, West Berlin remained outside the jurisdiction of the GDR. The German Democratic Republic was established in the Soviet Zone, while the Federal Republic was established in the three western zones. East Germany was a satellite state of the Soviet Union. Soviet occupation authorities began transferring administrative responsibility to German communist leaders in 1948, and the GDR began to function as a state on 7 October 1949. Soviet forces, however, remained in the country throughout the Cold War. Until 1989, the GDR was governed by the Socialist Unity Party (SED), though other parties nominally participated in its alliance organisation, the National Front of Democratic Germany.     What entity does 'saar protectorate' has the relation 'capital' with?
