Sinan Pasha became grand vizier five times between 1580 and his death in 1596. He had many rivals but he was also a very wealthy man. During his lifetime Sinan Pasha was criticized by Ottoman bureaucrats such as Mustafa Âlî who wrote that Sinan promoted Albanians into the Ottoman government and military. Contemporary Turkish historians also note that he remained close to his heritage and would give those of Albanian stock preference for high-level positions within the empire. In 1586, at his request, Sultan Murad III issued a decree exempting five villages in Luma from all taxes. Sinan Pasha constructed the fortress of Kaçanik in the Kosovo Vilayet with an "imaret" (soup kitchen), two "hans" (Inn), a "hamam" (Turkish bath) and a mosque that still bears his name.
