Question

Quizplus · Accepted Answer

The Spanish population in New Mexico and Texas was small, making it difficult for them to exert control over these territories. This allowed for indigenous groups like the Comanches and Apaches to challenge Spanish authority and for other European powers like the French to explore and settle in the area. While corruption in Mexico City may have contributed to difficulties in governing, the small Spanish population was a more significant factor.
