Passage: The 17th century is considered Amsterdam's Golden Age, during which it became the wealthiest city in the western world. Ships sailed from Amsterdam to the Baltic Sea, North America, and Africa, as well as present-day Indonesia, India, Sri Lanka, and Brazil, forming the basis of a worldwide trading network.
