What was the human hisory between North American Asia Eurasia and Europe before the 1450's?

I noticed the question you copied has exactly the same misspellings.

Go cheat somewhere else.

About 12,000 years ago people from northeastern Asia began migrating to the Americas. They probably crossed the Bering landbridge, although some may have come by boat along the shore.

The only European contact was the Viking brief settlement in what is now Nova Scotia, Canada.

To understand the human history between North America, Asia, Eurasia, and Europe before the 1450s, we need to look at the major historical developments and patterns of interaction between these regions. Here's an overview:

1. Beringia and Migration: It is widely believed that the first human inhabitants of the American continents migrated from Asia to North America over a land bridge called "Beringia" during the last Ice Age, which occurred between 20,000 to 10,000 years ago. These early migrants eventually spread across the Americas.

2. Native American Civilizations: By the time of European contact, North and South America were home to numerous indigenous civilizations, such as the Maya, Aztecs, Incas, and various Native American tribes. These civilizations had developed complex societies and cultural traditions.

3. Trade Networks: Before the 15th century, extensive trade networks connected various regions. The Silk Road, for instance, facilitated trade between Asia (particularly China) and Europe, allowing the exchange of goods, ideas, and technologies. Additionally, trade routes connected Asia with the Middle East, North Africa, and the Mediterranean.

4. Mongol Empire: The Mongol Empire, led by Genghis Khan and later his descendants, emerged in the 13th century and expanded throughout Asia and Eurasia. The Mongols facilitated trade and cultural exchange across the vast territories they controlled and played a significant role in connecting East Asia with Europe.

5. Crusades: The Crusades were a series of religious and military campaigns mounted by European Christians between the 11th and 13th centuries, aiming to reclaim control of the Holy Land (modern-day Israel and Palestine) from Muslim rulers. While the Crusades did not directly impact the Americas, they influenced European society, politics, and interactions with the wider world.

6. Exploration and Contact: European exploration and the Age of Discovery began in the 15th century. Prior to this, limited contact between Europe and Asia had occurred. Notable examples include Marco Polo's journey to China in the 13th century and the Viking exploration of North America around the 10th century (though this contact did not have lasting effects).

It's crucial to note that these are just some broad aspects of human history between these regions before the 1450s. For a more comprehensive understanding, delving into specific time periods, civilizations, and historical events will provide a more detailed picture.
