When Europeans arrived in the New World, they found civilizations like the Inca, Maya, and Aztec who had built huge cities with drainage, organized marketplaces, and frescoed pyramids. Among their achievements were metalworks, textiles, a written language, and ceramics. Other cultures like the Etowah, Makah, Anasazi, Iroquois, and the Hopewell had developed agriculture, basketry, fishing, and pottery making to provide for a growing population relatively free of disease and acclimated to their environment.
