Colonialism is when a country or government takes control of another country for money and power. It happens when a stronger country takes over a weaker country and takes control of how the country is run and how it is used. The country that was taken over is usually forced to use the language and customs of the colonizer and to provide resources such as money, food and other goods. Colonialism has made an impact on many countries around the world, both positive and negative. It has brought economic growth, education, and technological advancement, but it has also caused destruction of natural resources, destruction of cultures, and oppression of people.
