Who gave the formal recommendation to recognize Cosimo I of Florence, the second duke, after he defeated a hastily organized army of those wishing to restore the Republic of Florence?
Battle of Montemurlo On 1 or 2 August 1537 (both dates are given in sources), 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.
Italian War of 1551–59 The Italian War of 1551 (1551–1559), sometimes known as the Habsburg–Valois War and the Last Italian War, began when Henry II of France, who had succeeded Francis I to the throne, declared war against Holy Roman Emperor Charles V with the intent of recapturing Italy and ensuring French, rather than Habsburg, domination of European affairs. The war was the last of a series of wars between the same parties since 1521. Historians have emphasized the importance of gun powder technology, new styles of fortification to resist cannon fire, and the increased professionalization of the soldiers.
