History
Edit ThisOf Etruscan origin, it was a Roman colony with the name of "Sena Julia"; its importance grew in the Middle Ages, first as the seat of Lombard gastalds, and then of Counts under the Carolingian domination. After a long period of episcopal dominion (9th - 11th century) the town reached a peak of power after becoming a municipality (1147), undertaking a policy of expansion towards the bordering territories.
Confrontation with Florence was inevitable and the struggle lasted, with various vicissitudes, until 1555, when after a long siege, Siena was conquered by the Florentines, losing its autonomy and becoming part of the Duchy, sharing its fortunes until unification with Italy.
