<Li> Battle of Artemisium (480 BC) </Li> <Li> Battle of Salamis (480 BC) </Li> <P> Themistocles (/ θəˈmɪstəˌkliːz /; Greek: Θεμιστοκλῆς Greek pronunciation: (themistoklɛ̂ːs) Themistoklẽs; "Glory of the Law"; c. 524--459 BC) was an Athenian politician and general . He was one of a new breed of non-aristocratic politicians who rose to prominence in the early years of the Athenian democracy . As a politician, Themistocles was a populist, having the support of lower - class Athenians, and generally being at odds with the Athenian nobility . Elected archon in 493 BC, he convinced the polis to increase the naval power of Athens, a recurring theme in his political career . During the first Persian invasion of Greece he fought at the Battle of Marathon (490 BC) and was possibly one of the ten Athenian strategoi (generals) in that battle . </P> <P> In the years after Marathon, and in the run - up to the second Persian invasion of 480 - 479 BC, Themistocles became the most prominent politician in Athens . He continued to advocate a strong Athenian Navy, and in 483 BC he persuaded the Athenians to build a fleet of 200 triremes; these proved crucial in the forthcoming conflict with Persia . During the second invasion, he effectively exercised command of the Greek allied navy at the battles of Artemisium and Salamis in 480 BC . Due to subterfuge on the part of Themistocles, the Allies lured the Persian fleet into the Straits of Salamis, and the decisive Greek victory there was the turning point in the invasion, which ended the following year with the defeat of the Persians at the land Battle of Plataea . </P>
