The Ottoman Empire ruled over much of Eastern Europe and Central Asia from the 14th to 17th centuries. It was one of the largest and longest-lasting empires in history, significant in shaping the geopolitical landscape of Europe and the Middle East. The empire was known for its cultural, architectural, and military achievements, including the vast diversity of its subjects, which encompassed various religions and ethnic groups. Its decline began in the late 17th century, eventually leading to its dissolution after World War I and the establishment of modern nation-states in its territories.
