Explanation:

The Ottoman Empire began as one of the small Turkish states that emerged in Asia Minor during the decline of the Seljuk Empire. The Ottoman Turks gradually controlled the other Turkish states, survived the Mongol invasions and under the reign of Mehmed II (1451-1481) ended what was left of the Byzantine Empire. The first phase of the Ottoman expansion took place under the rule of Osman I (1288-1326) and continued in the reigns of Orkhan, Murad I and Beyazid I, at the expense of the territories of the Byzantine Empire, Bulgaria and Serbia. Bursa fell under his rule in 1326 and Adrianople in 1361. Ottoman victories in the Balkans alerted Western Europe about the danger that this Empire represented and were the central motive for the organization of the Hungarian Crusade of Sigismund. The site that the Ottomans put in Constantinople was broken thanks to Timur, leader of the Mongols, who took Beyazid prisoner in 1402, but Mongol control over the Ottomans lasted very little. Finally, the Ottoman Empire managed to conquer Constantinople in 1453.
