Rüstem Paşa was a grand vizier under the Ottoman sultan Kanuni Süleyman. He was born to a family of few resources in a Balkan village near Sarajevo in around 1500/906 AH. As a child, he entered the palace school and then the service of the Ottoman court where he was quickly promoted again and again until becoming vizier in 1544/951 AH. His productive reign, though interrupted by court intrigue for two years, was relatively long, and coincided with a period in which Ottoman Empire had reached an unprecedented level of power and prestige. Rüstem was known for both his financial abilities and his architectural patronage, having commissioned a number of buildings across the heart of the Ottoman Empire.
