Which factor played a major role in the decline of the ottiman empire?

The decline of the Ottoman Empire was significantly influenced by a combination of military defeats, territorial losses, and administrative inefficiencies. The Empire faced challenges from rising nationalist movements within its diverse population, leading to the loss of key territories in Europe and the Balkans. Additionally, economic difficulties and competition from European powers further weakened its stability. These factors, coupled with internal strife and corruption, contributed to the gradual disintegration of the Empire by the early 20th century.
