The Greek historian was born in 470 BC in Alimos. He was descended from a wealthy and aristocratic family. His father was the descendant of the kings of Thrace. He delighted to have the philosopher Anaxagoras as a teacher.
The great plague that hit Athens and killed about a quarter of the population risked to die but was saved.
In 424 BC, he was elected general and ordered to sail with the Athenian fleet and save Amphipolis, which threatened to fall into the hands of the Lacedaemonians.
Amphipolis was eventually captured and Thucydides was accused of treason and sentenced to death. In order to escape, he resorted to Peloponnesus, Sicily, and finally to Skatti Mathe (village of Thrace) where he died in 404 BC while for others in 397 BC .
In the years of exile he dealt with great detail with the writing of the Peloponnesian War. His narrative begins in 431 BC and ends abruptly in 411 BC, which suggests that he may even be murdered since his last proposal is half-finished His work was continued and completed by Xenophon. Thucydides' work is written in the ancient Attic dialect with excellent reason and style detailed descriptions, perhaps culminating in the "Epicurean of Pericles", which is one of the most brilliant texts of the ancient secretariat.
