Originally born in Albania (Topojani or Delvine) around 1520. He is usually called “Koca” in Turkish meaning great due to his age during his service as grand vizier. He served as grand vizier under Murad III. and Mehmed III.
With his elder brother Ayas Pasha’s assistance he entered the Royal College (Enderun). Under Sultan Suleyman he served in the palace as the meal supervisor. Later he served as Governor of Malatya first and then Egypt. In 1568 due to a revolt in Yemen he was put in charge of the army. He suppressed the revolt and joined together the split Ottoman district. Therefore he was entitled “Conqueror of Yemen”. During his return he performed pilgrimage in Mecca (1571).
This was a powerful time for the Ottoman government and following the conquest of Cyprus Tunisia also became Ottoman land. In 1572 Spanish navy took Tunisia and Sinan Pasha was ordered to lead the Navy to reconquer the land. Under his command legendary admiral Kilic Ali Pasha reconquered the land. Sinan Pasha was given a new title “Conqueror of Tunisia” as well as the rank of vizier.
Sinan Pasha was not just successful in military affairs but also in political and financial matters. He led peace talks with Iranian Shah Abbas as an example. He also inspected quality of coins and established new mints. Mines were run more efficiently with his regulations. He also had a great engineering project to join Black Sea and Gulf of Izmit using River Sakarya.
In 1593 he led a campaign against Austria with an important army force. This was the beginning of a long war until 1606. There were some victories in battles however the aimed conquest did not take place.
