Between 1750 and 1900, the Ottoman Empire and Qing Dynasty of China experienced turbulent times as industrialized European nations extended their political and economic control overseas through imperialism. Both empires resisted economic changes and faced challenges like nationalist revolts and loss of territory to European powers. By the late 1800s, the Ottoman Empire was seen as weak and the Qing Dynasty struggled against European incursions including the Opium Wars, leading to their eventual collapse in the early 20th century.
