What were the major similarities and differences between the oregon, texas, and california frontiers?

American settlement seemed to be unstoppable. By 1840, settlers had occupied all of the land

east of the Mississippi River and had organized most of the area into states. This rapid

expansion was caused by the market revolution and the extraordinary expansion of

transportation and commerce that accompanied the market revolution. The speed and success

of the expansion was a source of great pride for Americans and encouraged further

settlement. By 1848, the United States had become a continental nation.

a. The Fur Trade

From the 1670s to the 1840s, the fur trade was an important spur to North American

exploration. In 1824, William Henry Ashley instituted the rendezvous system, a yearly

trade fair (modeled on traditional Indian trade gatherings) to which trappers brought their

catch of furs. The event was a many-day affair characterized by trading, drinking, and

gambling, bringing together many nationalities and people of mixed race in a short-lived

community. By the 1840s the population of beaver in the West was virtually destroyed

and settlement would replace frontier trade.

The major differences between the three frontiers above are:

Orgeon moved its frontier because of the disease its native people were facing and because the number of white settlers was increasing as well.

Texas did it because its settlements were getting bigger and the people were moving with their slaves. When the state became independent, then the people who were born there dominated the economic and political order in the territory.

On the other hand, California was experiencing a population growth because of the discovery of gold that made the terrotory attractive.  

there is no money involved.

it is kinda pro bono
