Please answer the following question: Information:  - Areus I (died 265 BC) was Agiad King of Sparta from 309 to 265 BC, who died in battle near Corinth during the Chremonidean War. He was the grandson of Cleomenes II and was succeeded by his son Acrotatus II.  - Agesipolis II (died 369 BC), son of the king Cleombrotus I, succeeded his father and reigned as Agiad King of Sparta. His rule was exceedingly brief, from, at most, 371 until his death in 369 BC. He was succeeded by his brother Cleomenes II.  - 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 euro (sign: €; code: EUR) is the official currency of the eurozone, which consists of 19 of the member states of the European Union: Austria, Belgium, Cyprus, Estonia, Finland, France, Germany, Greece, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, the Netherlands, Portugal, Slovakia, Slovenia, and Spain. The currency is also officially used by the institutions of the European Union and four other European countries, as well as unilaterally by two others, and is consequently used daily by some 337 million Europeans . Outside of Europe, a number of overseas territories of EU members also use the euro as their currency.  - 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.  - In Greek mythology, Eurotas was a king of Laconia, the son of King Myles and grandson of Lelex, eponymous ancestor of the Leleges. He had no male heir, but he did have a daughter Sparta and wife Clete. Eurotas bequeathed the kingdom to Lacedaemon, the son of Taygete, after whom Mount Taygetus is named, and Zeus, according to Pausanias. Lacedaemon married Sparta and renamed the state after his wife.  - 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.  - Cleomenes II (died 309 BC) was Agiad King of Sparta from 369 to 309 BC. The son of Cleombrotus I, he succeeded his brother Agesipolis II. He was the father of Acrotatus I, the father of Areus I, and of Cleonymus, the father of Leonidas II.  - Cleombrotus I ( Greek :    ; died July 6 , 371 BC ) was a Spartan king of the Agiad line , reigning from 380 BC until 371 BC. Little is known of Cleombrotus ' early life . Son of Pausanias , he became king of Sparta after the death of his brother Agesipolis I in 380 BC , and led the allied Spartan - Peloponnesian army against the Thebans under Epaminondas in the Battle of Leuctra . His death and the utter defeat of his army led to the end of Spartan dominance in ancient Greece . Cleombrotus was succeeded by his son Agesipolis II. His other son was Cleomenes II. Many historians cite Cleombrotus as being a Pro-Theban Spartan ( meaning he had pro-Theban tendencies ) unlike his fellow king , Agesilaus II. He was blamed for the humiliating defeat at Leuctra by his contemporaries for being biased towards the enemy , though some modern historians do not believe that he was actually pro-Theban .  - Greece (' ), officially the Hellenic Republic (Greek: ' ), historically also known as Hellas ("" ), is a country in southeastern Europe.  Greece's population is approximately 10.955 million as of 2015. Athens is the nation's capital and largest city, followed by Thessaloniki.  - Leonidas II (Greek:  B, "Lion's son", "Lion-like"), was the 28th Agiad King of Sparta from 254 to 235 BC. He was raised at the Persian Court, and according to Plutarch's Life of Agis IV, he married a Persian woman. According to other sources, this non-Spartan wife was actually a Seleucid, possibly the daughter of Seleucus I Nicator by his Persian wife Apama. She was therefore not fully Persian, but half-Macedonian and half-Persian. His Persian-influenced lifestyle, his non-Spartan (therefore foreign) wife and his half-Spartan children would all be made issues by the ephor Lysander, the co-king Agis IV and their supporters.  - Acrotatus I (Gr. ) was the son of Cleomenes II, king of Sparta. He incurred the displeasure of an influential group of Spartan citizens by opposing the decree which was to release from infamy all who had fled from the battle in which Antipater defeated Agis in 331 BC. He was thus glad to accept the offer from the Agrigentines who had asked Sparta for assistance in 314 BC against Agathocles of Syracuse.   - Epaminondas ("Epameinondas"; d. 362 BC) was a Theban general and statesman of the 4th century BC who transformed the Ancient Greek city-state of Thebes, leading it out of Spartan subjugation into a pre-eminent position in Greek politics. In the process he broke Spartan military power with his victory at Leuctra and liberated the Messenian helots, a group of Peloponnesian Greeks who had been enslaved under Spartan rule for some 230 years after being defeated in the Messenian War ending in 600 BC. Epaminondas reshaped the political map of Greece, fragmented old alliances, created new ones, and supervised the construction of entire cities. He was also militarily influential and invented and implemented several major battlefield tactics.
