Colonialism is the process of subjugation of power by one powerful country over a weak country.

Explanation:
Colonialism is a political and economic system in which a powerful country extends its control over a weaker country or territory. The country that holds the power is called the colonizer, while the weaker country or territory is known as the colony. Colonialism can take different forms, such as settler colonialism, where the colonizers move into the colony and establish their own society, or indirect colonialism, where the colonizer rules through local elites.

Colonialism has been a major force in shaping the world we live in today. It has had a profound impact on the cultures, economies, and political systems of the colonized countries and has often resulted in the exploitation of their resources and people. Many countries that were once colonies still struggle with the legacy of colonialism, including poverty, inequality, and political instability.

Some of the key features of colonialism include:

1. Control over territory: The colonizer takes control of the land and resources of the colony, often through force or the threat of force.

2. Economic exploitation: The colonizer extracts resources and labor from the colony to benefit its own economy, often through forced labor or unequal trade agreements.

3. Cultural domination: The colonizer often imposes its own language, religion, and customs on the colony, suppressing local traditions and identities.

4. Political control: The colonizer establishes a system of government in the colony that is often undemocratic and serves the interests of the colonizer rather than the local population.

In conclusion, colonialism is a process of subjugation of power by one powerful country over a weak country. It has had a profound impact on the world and continues to shape global politics and economics today.
