Why did spian need to establish a buffer zone in northern new Spain?

Answer 1

Spain sought to establish a buffer zone in northern New Spain primarily to protect its colonial territories from encroachment by rival powers, particularly France and Britain. The buffer zone served as a barrier against potential invasions and conflicts, allowing Spain to secure its trade routes and resources. Additionally, it aimed to facilitate the spread of Spanish influence and control over indigenous populations in the region. By creating this zone, Spain hoped to strengthen its foothold in North America and maintain stability in its colonial holdings.
