Ali Bey was a sixteenth century Emir of the Ottoman Empire. Under his rule, the Ottoman Empire expanded westward into Europe, coming into greater prominence. One of his closest confidants was the artist, Wohat. According to legend, he credited the possession of the Invincible Ruby as source of his military expansion of the empire. When the ruby was lost, his confidence left, and the empire began to collapse. Ali Bey built a Ali Bey's Palace in the region around modern Mombasa, Kenya. The ruby eventually ended up in a burial chamber in the palace.
