The two rivers that marked the northern boundary between Spanish territory and the United States in 1819 were the Sabine River and the Red River. This boundary was established through the Adams-Onís Treaty, which defined the limits of Spanish territory in North America. The treaty aimed to settle disputes and clarify territorial claims between the U.S. and Spain.

The indigenous peoples of the Southwest, particularly the Pueblo people, acted as a buffer against northern expansion of Spanish colonies. Their settlements were located north of New Spain's territory, and their resistance to Spanish colonization prevented further advancement by the Spanish into present-day New Mexico and beyond.

At least in the Louisiana Territory, the French and Spanish efforts differed. The French were trying to connect a Canadian and Northern territory to the gulf. This would provide them with supplies through the Mississippi River and Gulf of Mississippi. The Spanish however, took a more militaristic approach. The Territory for them was a defensive position. The colonization of the French did not go as well, due to oppresive slavery, bad equipment, and low immigration numbers to the Territory. The Spanish faired better due to less oppressive slavery (slaves could actually buy themselves out of slavery) and an open door immigration act. It should be noted that while this immigration act allowed the spanish to jump into the territory in huge numbers, this allowed for the seeds of its demise to be sowed as well. The Americans allowed into the territories were still identifying with the original 13 colonies, and tried to hold onto their pride and rights even in the Spanish controlled territory.
The United States was given all of the land of the 13 colonies and west to the Mississippi River. This did not include French and Spanish settlements and forts along the Gulf Coast. The northern boundary was the Great Lakes.
The Mississippi River helped form the boundary between British and Spanish territory in 1763.
