1. Beginning in the 1400s, European powers like Portugal, Spain, France, and the Netherlands began exploring and colonizing other parts of the world seeking new trade routes, resources, and ways to spread Christianity.
2. Portugal led the initial wave of exploration down the west coast of Africa. Spain then conquered much of Central and South America, devastating native cultures like the Aztecs and Incas.
3. The colonization established the Atlantic slave trade, with over 10 million Africans ultimately transported to the Americas as slaves. European trading companies also established control over ports and trade in Asia.
