The Ottoman Empire lasted from 1299 until 1923, and was at its most powerful in the 16th and 17th Centuries. Constantinople - modern Istanbul - was its capital from 1453. Its most powerful leader was the Sultan Suleiman the Magnificant, who ruled from 1520 - 1566. The number of countries dominated by the empire was staggering, and included parts of Europe, Africa and Asia. In cultural and artistic terms, the melding of these regions produced fascinating results. The architecture, for example, bore Greek, Persian and Islamic features. The Baroque and Rococo influences from Western Europe also found their way over.
