Period 1 (1491-1607): Native American Societies and European Contact

This period covers the time from pre-Columbian Native American societies to early European exploration and settlement in the Americas. It is crucial for understanding the foundations of American history.

Why does period 1 start with 1491? 1491 represents the year before Christopher Columbus's arrival in the Americas, marking the last year of solely indigenous control of the continents.

Key points:

  • Prehistoric migration across the Bering land bridge populated the Americas
  • By 1492, an estimated 54 million people lived in the Americas
  • Advanced civilizations like the Aztecs, Incas, and Mayans developed sophisticated urban centers and agricultural practices
  • Three sister farming (maize, beans, and squash) was a crucial agricultural innovation

Highlight: The introduction of maize cultivation by the Aztecs, Incas, and Mayans to North America became a primary crop for Native Americans, enabling permanent settlements and advancements in science and technology.

Definition: Three sister farming is an agricultural technique where corn, beans, and squash are planted together to maximize yields and soil health. This method was widely used in the Southwest, Southeast, and Northeast regions of North America.

Example: The Aztecs built large, elaborate cities and made accurate astronomical observations, demonstrating their advanced civilization despite lacking modern technology.

This app is really great. There are so many study notes and help [...]. My problem subject is French, for example, and the app has so many options for help. Thanks to this app, I have improved my French. I would recommend it to anyone.

Wow, I am really amazed. I just tried the app because I've seen it advertised many times and was absolutely stunned. This app is THE HELP you want for school and above all, it offers so many things, such as workouts and fact sheets, which have been VERY helpful to me personally.
