Мехмед III
Mehmed III was an idle ruler, leaving government to his mother Safiye Sultan, the valide sultan. His first major problem was the rivalry between two of his viziers, Serdar Ferhad Pasha and Koca Sinan Pasha, and their supporters. His mother and her son-in-law Damat Ibrahim Pasha supported Koca Sinan Pasha and prevented Mehmed III from taking control of the issue himself. The issue grew to cause major disturbances by janissaries. On 7 July 1595, Mehmed III finally sacked Serdar Ferhad Pasha from the position of Grand Vizier due to his failure in Wallachia and replaced him with Sinan.
