Please answer the following question: Information:  - Cleisthenes ("Kleisthéns"; also Clisthenes or Kleisthenes) was a noble Athenian of the Alcmaeonid family. He is credited with reforming the constitution of ancient Athens and setting it on a democratic footing in 508/7 BC. For these accomplishments, historians refer to him as "the father of Athenian democracy." He was the maternal grandson of the tyrant Cleisthenes of Sicyon, as the younger son of the latter's daughter Agariste and her husband Megacles. Also, he was credited with increasing the power of the Athenian citizens assembly and for reducing the power of the nobility over Athenian politics.  - In Ancient Greece, a deme or demos was a suburb of Athens or a subdivision of Attica, the region of Greece surrounding Athens. Demes as simple subdivisions of land in the countryside seem to have existed in the 6th century BC and earlier, but did not acquire particular significance until the reforms of Cleisthenes in 508 BC. In those reforms, enrollment in the citizen-lists of a deme became the requirement for citizenship; prior to that time, citizenship had been based on membership in a phratry, or family group. At this same time, demes were established in the city of Athens itself, where they had not previously existed; in all, at the end of Cleisthenes' reforms, Attica was divided into 139 demes to which one should add Berenikidai, established in 224/223 BC, Apollonieis (201/200 BC) and Antinoeis (126/127). The establishment of demes as the fundamental units of the state weakened the gene, or aristocratic family groups, that had dominated the phratries.  - The Peloponnesian League was an alliance in the Peloponnesus from the 6th to the 4th centuries BC. It is known mainly for being one of the two rivals in the Peloponnesian War (431404 BC)  - The Clouds ( Ancient Greek :  Nephelai ) is a Greek comedy play written by the celebrated playwright Aristophanes . A lampooning of intellectual fashions in classical Athens , it was originally produced at the City Dionysia in 423 BC and was not as well - received as the author had hoped , coming last of the three plays competing at the festival that year . It was revised between 420 - 417 BC and was thereafter circulated in manuscript form . No copy of the original production survives , and scholarly analysis indicates that the revised version is an incomplete form of Old Comedy . This incompleteness , however , is not obvious in translations and modern performances . Retrospectively , The Clouds can be considered the world 's first extant ' comedy of ideas ' , and is considered by literary critics to be among the finest example of the genre . The play also , however , remains notorious for its caricature of Socrates , and is mentioned in Plato 's Apology as a contributor to the philosopher 's trial and execution .  - Athens ("Athína" ) is the capital and largest city of Greece. Athens dominates the Attica region and is one of the world's oldest cities, with its recorded history spanning over 3,400 years, and its earliest human presence starting somewhere between the 11th and 7th millennia BC. Classical Athens was a powerful city-state that emerged in conjunction with the seagoing development of the port of Piraeus, which had been a distinct city prior to its 5th century BC incorporation with Athens. A centre for the arts, learning and philosophy, home of Plato's Academy and Aristotle's Lyceum, it is widely referred to as the cradle of Western civilization and the birthplace of democracy, largely because of its cultural and political impact on the European continent, and in particular the Romans. In modern times, Athens is a large cosmopolitan metropolis and central to economic, financial, industrial, maritime, political and cultural life in Greece. In 2015, Athens was ranked the world's 29th richest city by purchasing power and the 67th most expensive in a UBS study.  - 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.  - The Delian League, founded in 478 BC, was an association of Greek city-states, members numbering between 150 173, to 330 under the leadership of Athens, whose purpose was to continue fighting the Persian Empire after the Greek victory in the Battle of Plataea at the end of the Second Persian invasion of Greece. The League's modern name derives from its official meeting place, the island of Delos, where congresses were held in the temple and where the treasury stood until, in a symbolic gesture, Pericles moved it to Athens in 454 BC.  - Aristophanes (or  ; c. 446  c. 386 BC), son of Philippus, of the deme Kydathenaion, was a comic playwright of ancient Athens. Eleven of his forty plays survive virtually complete. These, together with fragments of some of his other plays, provide the only real examples of a genre of comic drama known as Old Comedy, and are used to define it.  - The Lamian War, or the Hellenic War (323322 BC) was fought by a coalition of Greek cities including Athens and the Aetolian League against Macedon and its ally Boeotia. The war ended in a Macedonian victory.  - The Peloponnesian War (431404 BC) was an ancient Greek war fought by Athens and its empire against the Peloponnesian League led by Sparta. Historians have traditionally divided the war into three phases. In the first phase, the Archidamian War, Sparta launched repeated invasions of Attica, while Athens took advantage of its naval supremacy to raid the coast of the Peloponnese and attempt to suppress signs of unrest in its empire. This period of the war was concluded in 421 BC, with the signing of the Peace of Nicias. That treaty, however, was soon undermined by renewed fighting in the Peloponnese. In 415 BC, Athens dispatched a massive expeditionary force to attack Syracuse in Sicily; the attack failed disastrously, with the destruction of the entire force, in 413 BC. This ushered in the final phase of the war, generally referred to either as the Decelean War, or the Ionian War. In this phase, Sparta, now receiving support from Persia, supported rebellions in Athens' subject states in the Aegean Sea and Ionia, undermining Athens' empire, and, eventually, depriving the city of naval supremacy. The destruction of Athens' fleet at Aegospotami effectively ended the war, and Athens surrendered in the following year. Corinth and Thebes demanded that Athens should be destroyed and all its citizens should be enslaved, but Sparta refused.  - Pericles ("Perikls", in Classical Attic; c. 495  429 BC) was a prominent and influential Greek statesman, orator and general of Athens during the Golden Agespecifically the time between the Persian and Peloponnesian wars. He was descended, through his mother, from the powerful and historically influential Alcmaeonid family.  - Sparta (Doric Greek: ; Attic Greek: ) was a prominent city-state in ancient Greece. In antiquity the city-state was known as Lacedaemon, while the name Sparta referred to its main settlement on the banks of the Eurotas River in Laconia, in south-eastern Peloponnese. Around 650 BC, it rose to become the dominant military land-power in ancient Greece.  - The city of Athens during the classical period of Ancient Greece (508322 BC) was the major urban center of the notable polis (city-state) of the same name, located in Attica, Greece, leading the Delian League in the Peloponnesian War against Sparta and the Peloponnesian League. Athenian democracy was established in 508 BC under Cleisthenes following the tyranny of Isagoras. This system remained remarkably stable, and with a few brief interruptions remained in place for 180 years, until 322 BC (aftermath of Lamian War). The peak of Athenian hegemony was achieved in the 440s to 430s BC, known as the Age of Pericles.  - Hegemony (or , or  "leadership, rule") is the political, economic, or military predominance or control of one state over others. In ancient Greece (8th century BCE  6th century CE), "hegemony" denoted the politicomilitary dominance of a city-state over other city-states. The dominant state is known as the "hegemon".  - Democracy ("" literally "rule of the commoners"), in modern usage, is a system of government in which the citizens exercise power directly or elect representatives from among themselves to form a governing body, such as a parliament. Democracy is sometimes referred to as "rule of the majority". Democracy was originally conceived in Classical Greece, where political representatives were chosen by a jury from amongst the male citizens: rich and poor.  - Old Comedy ("archaia") is the first period of the ancient Greek comedy, according to the canonical division by the Alexandrian grammarians. The most important Old Comic playwright is Aristophanes  whose works, with their daring political commentary and abundance of sexual innuendo, effectively define the genre today. Aristophanes satirized and lampooned the most prominent personalities and institutions of his time, as can be seen, for example, in his scurrilous portrayal of Socrates in "The Clouds", and in his racy anti-war farce "Lysistrata". Aristophanes was only one of a large number of comic poets, however, working in Athens in the late 5th century BC; his biggest rivals were Hermippus and Eupolis.  - Polis, plural poleis literally means city in Greek. It can also mean citizenship and body of citizens. In modern historiography, "polis" is normally used to indicate the ancient Greek city-states, like Classical Athens and its contemporaries, and thus is often translated as "city-state".  - Attica (or ; or ) is a historical region that encompasses the city of Athens, the capital of Greece. The historical region is centered on the Attic peninsula, which projects into the Aegean Sea. The modern administrative region of Attica is more extensive than the historical region and includes the Saronic Islands, Cythera, and the municipality of Troizinia on the Peloponnesian mainland. The history of Attica is tightly linked with that of Athens, which, from the classical period, was one of the most important cities in the ancient world.
