Answer:
Imperialism is the state policy, practice, or advocacy of extending power and dominion, especially by direct territorial acquisition or by gaining political and economic control of other territories and peoples.
The five main motives for imperialism include exploration, economic expansion, increased political power, the diffusion of ideological beliefs, and the spreading of religious beliefs and practices to others.
The four major motives for imperialism are economic, strategic, religious and political. These motives helped great empires expand their territory and brought new cultures and languages to both the colonised countries and the countries colonising them.
