Battle of Montemurlo
On 1 or 2 August 1537, near the Tuscan village of Montemurlo, the forces of the newly installed Duke Cosimo I of Florence defeated a hastily organized army of those who wished to overthrow the Medici and restore the Republic of Florence. Following the battle, Cosimo's bloody vengeance on all those who opposed Medici rule effectively ended organized opposition to his family in Florence. The victory led to the decision of Emperor Charles V to formally recognize Cosimo as Duke of Florence on 30 September 1537.
