This period before European contact is often referred to as 1491 – a symbolic date used because of the scarcity of written records. Before European contact, Native American societies across North America adapted their lifestyles to their environments. The cultivation of maize (corn) began in the Southwest region and expanded across North America. In the Southwest, which had very little rainfall, Native Americans used irrigation techniques to bring water to their fields. In the Great Plains, most Natives lived as migratory hunters following the plentiful herds of bison that fed on the region’s lush grasslands. Settled agriculture was a common practice in the Northeast and Southeast regions. Native Americans in these regions tended to live in permanent settlements, growing crops such as corn, squash, and beans to supplement hunting and gathering. In California and the Northwest Coast, Native tribes supplemented their diets with fish and sea animals.  \nEARLY EUROPEAN EXPLORATION OF THE AMERICAS  \nIn the 1400s, European nations along the Atlantic Coast, such as Spain, France, and England, competed with each other for land and resources. After completing the Reconquista (the Christian reconquest of Muslim-held lands) in Spain, Ferdinand and Isabella commissioned Christopher Columbus to sail west and establish a direct trade relationship with Asia that would bring new wealth to Spain and new converts to the Christian religion. In 1492, Columbus made landfall in the Americas, mistakenly believing that he had reached the “Indies,” and claimed the new lands for the Spanish crown. After it was confirmed in the early 1500s that Columbus had discovered new lands, Spanish, French, and English monarchs financed voyages of exploration to establish land claims in the Americas.  \n| THE COLUMBIAN EXCHANGE |  | |  |\n| --- | --- | --- | --- |\n| The Columbian Exchange is a term that scholars use to describe the exchange of crops, animals, diseases, ideas, technologies, and people that created a permanent trade relationship between the Old World (Europe, Africa, and Asia) and the New World (the Americas) . |  |  |  |\n| NEW WORLD ORIGINS\u003Cbr>Maize (Corn) Potatoes Tomatoes\u003Cbr>Tobacco Chocolate | OLD WORLD ORIGINS\u003Cbr>Livestock Horses Sugar Christianity Diseases |  |  |\n|  |  | New World foods like turkey, pumpkins, and potatoes are key parts of traditional Thanksgiving dinners. |  |\n\nThe Columbian Exchange also played a major role in shifting the European economy from feudalism (an agriculture-based economy where wealth was measured by land ownership) to capitalism (an economy based on trade and exchanging money) .  \nSPANISH EXPLORATION AND CONQUEST  \nThe Spanish were the first Europeans to successfully colonize the Americas. Conquistadors (conquerors) sailed to the Americas with armies to build a Spanish empire in the New World. The most famous of these conquistadors was Hernán Cortés, who conquered the Aztec Empire in present-day Mexico. Although equipped with superior technologies, such as firearms, horses, and steel swords, the success of the Spanish conquest was also aided by a number of deadly diseases, such as smallpox, which wiped out a significant portion (up to 90 percent) of the Native population. The horses introduced by the Spanish made their way to the Great Plains, where American Indians began using them in their bison hunts.  \nLABOR, SLAVERY, AND CASTE IN THE SPANISH COL","cbCailZo66zAbNZC","https://ap.wps.com/l/cbCailZo66zAbNZC","pdf",379297,"English","# NATIVE AMERICAN SOCIETIES BEFORE EUROPEAN CONTACT\n# EARLY EUROPEAN EXPLORATION OF THE AMERICAS\n# THE COLUMBIAN EXCHANGE\n# SPANISH EXPLORATION AND CONQUEST\n# LABOR, SLAVERY, AND CASTE IN THE SPANISH COLONIES\n# UNIT TIMELINE","[{\"question\":\"What does APUSH Unit 1 (1491–1607) focus on?\",\"answer\":\"It covers Native American societies before European contact and the early (pre-English) exploration and colonization of the Americas, including the Spanish conquest and related systems of labor and society.\"},{\"question\":\"How was the date 1491 used in the unit?\",\"answer\":\"1491 is a symbolic date used because written records are scarce for the period before European contact.\"},{\"question\":\"What was the Columbian Exchange and why does it matter?\",\"answer\":\"It describes the exchange of crops, animals, diseases, ideas, technologies, and people between the Old World and the New World, creating a permanent trade relationship and shifting economic structures in Europe.\"}]","APUSH Unit 1 Review Guide - 1491-1607 - For Students Preparing for the AP United States History Exam | PDF",1790682419]
