The Dutch Empire was a wealthy and ambitious empire in the early 17th century despite having a small population of only 1.5 million people. The Dutch dominated northern and western European trade routes as well as fishing and whaling. Amsterdam was a major center for shipping, banking, insurance, and manufacturing in northern Europe. The Dutch also stole the Portuguese sugar trade from American plantations and the slave trade from West Africa to the Americas, capturing key trading posts and dominating sugar production in Brazil. However, by the mid-1600s the Dutch faced attacks from former allies like the English and French as their power grew.
