Cause

The Italian War of 1551–1559 set the Duchy of Florence and the Holy Roman Empire under Charles V against the Republic of Siena, which allied with France. Siena's resistance and French support prompted a major military confrontation in the Tuscan countryside near Arezzo.

Event

On August 2, 1554, an Imperial-Florentine army under Gian Giacomo Medici clashed with a Sienese-French force led by Piero Strozzi near Marciano della Chiana. The Imperial-Florentine side inflicted a crushing defeat on the opposing army in a decisive pitched battle.

Consequence

The defeat broke the military power of the Republic of Siena and its French allies in Tuscany. Unable to continue effective resistance, Siena was subsequently absorbed into the Duchy of Florence, ending its existence as an independent republic.
