The Turkish empire, established in northern Anatolia by Osman I at the end of the 13th century and expanded by his successors to include all of Asia Minor and much of southeastern Europe. After setbacks caused by the invasion of the Mongol ruler Tamerlane in 1402, the Ottomans captured Constantinople in 1453, and the empire reached its zenith under Suleiman in the mid 16th century. It had greatly declined by the 19th century and collapsed after World War I.
