sienna
A city of Central Italy, about 30 miles southeast from Florence. In the Middle Ages, Siena became one of the powerful city republics of Italy.

Through intestine quarrels it was subjugated by the emperor Charles V., and given to his son in 1555, who ceded it to Cosmo of Tuscany, 1557. It was incorporated with France, 1808-14.
