European Imperialism refers to the period during the late 19th and early 20th centuries when European powers expanded their territories by colonizing large parts of Africa, Asia, and the Americas. Countries like Britain, France, and Germany sought to increase their wealth and influence by acquiring land and resources, often justifying their actions with ideas of cultural superiority. This expansion led to significant changes in the colonized regions, including the introduction of new governance systems, economic exploitation, and cultural exchanges. However, it also resulted in conflicts, resistance movements, and lasting impacts on the societies and economies of the affected areas.
