Concept:Colonisation is the process where a powerful country takes control of a weaker country, leading to major changes in its politics, economy, society, and culture.
Explanation:The question describes a situation where one country subjugates another, resulting in political, economic, social, and cultural changes. This matches the definition of colonisation.
The word comes from the Latin "colōnia," meaning a place for agriculture. Colonisation is a policy where a stronger power extends control over weaker peoples or areas.
Its main goal is economic benefit for the colonising country. It involves dominating the local population in all spheres of life.
There are two main types: settler colonialism (large number of immigrants settle and dominate) and exploitation colonialism (few immigrants, focus on resource extraction).
In contrast, a confederacy is a group joined for a common purpose; mercantile relates to trade; and renaissance means rebirth, especially in arts and knowledge.
Only colonisation fits the description of subjugation causing widespread changes.
