Rüstem Pasha
After the conquest of Constantinople in 1453, the Ottoman sultans started a huge building programme. In these buildings, especially those commissioned by Süleyman, his wife Hürrem (Roxelana) and his Grand Vizier Rüstem Pasha, large quantities of tiles were used. The Sultan Ahmed Mosque in Istanbul (the "Blue Mosque") alone contains 20,000 tiles. The Rüstem Pasha Mosque is more densely tiled and tiles were used extensively in the Topkapı Palace. As a result of this demand, tiles dominated the output of the Iznik potteries.
