After more than 6 centuries of existence and development, the Ottoman Empire collapsed. There were many reasons for the decline of this empire. Among these are the fact that since the 17th century, the military power of the Ottoman Empire began to wane.
The Ottoman conquests had successive failures such as the failed conquest of Vienna in 1683.
The Balkan Wars took place in 1912 and 1913, causing the Ottoman Empire to suffer great losses when it lost 33% of its territory and 20% of its population.
Although the Ottoman Empire made many reforms to restore the country to its glory days, they were to no avail. When World War I broke out, the Ottoman Empire allied with Germany in hopes of returning to its glory days soon.
As a result, Germany was defeated and the Ottoman Empire completely collapsed when two-thirds of its soldiers died and about 3 million civilians died. Accordingly, the once mighty empire disappeared from the world map.
