How did actions among European, African and Native American Cultures shape early American History?

Explanation:

The development of the Atlantic slave trade forever changed the course of European settlement in the Americas. Other transatlantic travelers, including diseases, goods, plants, animals, and even ideas like the concept of private land ownership, further influenced life in America during the sixteenth and seventeenth centuries

the american rail road was the most influential and useful transportation system developed in the 1800's with steam locomotives and in the very late 1800's and early 1900's diesel electric locomotives being used to transport goods and people around the newly expanded united states!
