Empire created by Turkish tribes in Anatolia. One of the most powerful states in the world during the 15th and 16th centuries, it spanned more than 600 years and came to an end only in 1922, when it was replaced by the Turkish Republic and various successor states in southeastern Europe and the Middle East. At its height the empire included most of southeastern Europe to the gates of Vienna, including modern Hungary, Serbia, Bosnia, Romania, Greece, and Ukraine; Iraq, Syria, Israel, and Egypt; North Africa as far west as Algeria; and most of the Arabian Peninsula.
Although the Ottoman Empire is not considered a European kingdom per se, Ottoman expansion had a profound impact on a continent already stunned by the calamities of the fourteenth and fifteenth centuries and the Ottoman Turksmust, therefore, be considered in any study of Europe in the late Middle Ages. The ease with which the Ottoman Empire achieved military victories led Western Europeans to fear that ongoing Ottoman success would collapse the political and social infrastructure of the West and bring about the downfall of Christendom. Such a momentous threat could not be ignored and the Europeans mounted crusades against the Ottomans in 1366, 1396, and 1444, but to no avail. The Ottomans continued to conquer new territories.
