Answer the following question: Information:  - Untermensch ("underman", "sub-man", "subhuman"; plural: "Untermenschen") is a term that became infamous when the Nazis used it to describe "inferior people" often referred to as "the masses from the East", that is Jews, Roma, and Slavs (mainly ethnic Poles, Serbs, and later also Russians). The term was also applied to most Blacks, and persons of color, with some particular exceptions. Jewish people were to be exterminated in the Holocaust. Roma, and the physically and mentally disabled were also to be exterminated. According to the "Generalplan Ost", the Slavic population of East-Central Europe was to be reduced in part through mass murder, with a majority expelled to Asia or used slave labor in the Reich. A few populations deemed partially "Aryan" in origin were to be Germanized (see kidnapping of children by Nazi Germany). These concepts were an important part of the Nazi racial policy. While the Nazis were inconsistent in the implementation of their policy, (mostly implementing the Final Solution while implementing "Generalplan Ost") the democidal death toll was in tens of millions of victims. It is related to the concept of life unworthy of life, a more specific term which originally referred to the severely disabled involuntarily euthanised in Action T4, and was eventually applied to the extermination of the Jews.  - 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.  - A minority group refers to a category of people differentiated from the social majority, those who hold the majority of positions of social power in a society, and it may be defined by law. Rather than a relational "social group", as the term would indicate, "minority group" refers to the above-described. The differentiation can be based on one or more observable human characteristics, including: ethnicity, race, religion, caste, gender, wealth, health or sexual orientation. Usage of the term is applied to various situations and civilizations within history despite its popular misassociation with a numerical, statistical minority (Barzilai, 2010). In the social sciences, the term "minority" is used to refer to categories of persons who hold fewer positions of social power.  - A city is a large and permanent human settlement. Although there is no agreement on how a city is distinguished from a town in general English language meanings, many cities have a particular administrative, legal, or historical status based on local law.  - The German extermination camps or death camps were designed and built by Nazi Germany during World War II (193945) to systematically kill millions of Jews, Slavs and others whom the Nazis considered "Untermenschen", primarily by gassing, but also in mass executions and through extreme work under starvation conditions.  - Nazi Germany is the common English name for the period in German history from 1933 to 1945, when Germany was governed by a dictatorship under the control of Adolf Hitler and the Nazi Party (NSDAP). Under Hitler's rule, Germany was transformed into a fascist state in which the Nazi Party took totalitarian control over nearly all aspects of life. The official name of the state was "Deutsches Reich" from 1933 to 1943 and "Großdeutsches Reich" ("Greater German Reich") from 1943 to 1945. The period is also known under the names the Third Reich and the National Socialist Period (abbreviated as "NS-Zeit"). The Nazi regime came to an end after the Allied Powers defeated Germany in May 1945, ending World War II in Europe.  - Slavs are the largest Indo-European ethno-linguistic group in Europe. They are native to Central Europe, Eastern Europe, Southeastern Europe, Northeastern Europe, North Asia and Central Asia. Slavs speak Slavic languages of the Balto-Slavic language group. From the early 6th century they spread to inhabit most of Central, Eastern and Southeastern Europe.   - University over the Abyss is a book about the educational and cultural life in the Terezín ( German : Theresienstadt ) ghetto .

The lagoon and a part of the city are listed as a World Heritage Site.  - A ghetto is a part of a city in which members of a minority group live, especially because of social, legal, or economic pressure. The term was originally used in Venice to describe the part of the city to which Jews were restricted and segregated.

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.
