Vlad the Impaler
First rule

Upon the death of his father and elder brother, Vlad became a potential claimant to Wallachia. Vladislav II of Wallachia accompanied John Hunyadi, who launched a campaign against the Ottoman Empire in September 1448. Taking advantage of his opponent's absence, Vlad broke into Wallachia at the head of an Ottoman army in early October. He had to accept that the Ottomans had captured the fortress of Giurgiu on the Danube and strengthened it.

The Ottomans defeated Hunyadi's army in the Battle of Kosovo between 17 and 18 October. Hunyadi's deputy, Nicholas Vízaknai, urged Vlad to come to meet him in Transylvania, but Vlad refused him. Vladislav II returned to Wallachia at the head of the remnants of his army. Vlad was forced to flee to the Ottoman Empire by 7 December 1448.

Therefore, we ask you to have patience until we see what has happened to.... If he returns from the war, we will meet him, and we will make peace with him. But if you will be our enemies now, and if something happens,... you will have to answer for it before God
