Османског, or the Ottoman Empire, was a vast and powerful state that existed from the late 13th century until the early 20th century. It originated in northwestern Anatolia and expanded to include parts of Europe, Asia, and Africa. The empire was known for its rich culture, architecture, and significant contributions to art and science. The Ottoman rulers, known as sultans, established a complex administrative system and promoted trade and commerce. The empire reached its peak in the 16th and 17th centuries under Suleiman the Magnificent. However, it began to decline in the 18th century and ultimately dissolved after World War I, leading to the establishment of modern-day Turkey.
