"Themistocles (/θəˈmɪstəkliːz/; 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.[citation needed]" - (en.wikipedia.org 19.10.2020)
