European powers explored and colonized much of the world between the 15th-17th centuries seeking to spread Christianity, gain territory, and profit economically. Portugal led exploration down the coast of Africa. Spain established vast American and Asian empires through conquistadors like Pizarro. The British, French, and Dutch later established global trading empires through colonization of North America, the Caribbean, Africa, Asia, and the Pacific. European exploration and colonization transformed global politics and economics and led to the rise of powerful Western empires.
