The Ottoman Empire lasted from 1299 to 1923. It was centered in Turkey and controlled the eastern and southern lands around the Mediterranean Sea. The empire was founded by Osman I around 1299, and was most powerful from around 1400 to 1600, when it controlled trade and politics in southeastern Europe, southwest Asia, and northern Africa.
Suleiman the Magnificent was one of the most powerful rulers.
The empire was a collection of conquered countries. The Sultan sent governors to rule these countries or provinces.
In later years, the Ottoman Empire began to weaken. The empire stopped expanding and Europe and India grew stronger economically.
In the latter part of the 19th century, the Ottoman Empire became known as “the sick man of Europe.” The empire was defeated in World War I and broke into pieces.
