This document summarizes the decline of three major empires - the Ottoman Empire, Qing Chinese Empire, and Japanese Empire - between 1750-1900 as well as the rise of European imperialism during this period. It discusses how the Ottoman and Qing Empires resisted economic change and underestimated European power, leading to their decline, while Japan modernized and industrialized without foreign debt to avoid this fate. It also outlines how Europeans colonized much of Africa and Asia in this era due to new technologies, ideologies of racial superiority, and pursuit of profits from new territories.
