What were the causes of Spanish exploration in New Spain?

Spain's search for wealth was a major motive for exploration. The Spanish were in search of gold and silver to replenish the Spanish Crown's coffers, which were depleted after the completion of the Reconquista, a seven-century endeavor to reclaim Iberian territory from Muslim control.

A desire for God and glory: The missionary impulse to expand the Catholic faith was also a motivator. The Spanish viewed it as their duty to convert the indigenous peoples of the Americas to Christianity.

A desire to extend Spain's empire: Spain was the leading global superpower in the 16th century. As a result, they sought to establish an empire in order to solidify their power and prominence in the world.

A desire for discovery: The Spanish had an innate curiosity about the globe. They wished to study and explore the newly found territories in order to acquire knowledge and establish new commerce routes.

A quest for adventure: Many Spanish explorers were interested in adventure and risk-taking. The notion of traveling to new areas, meeting new peoples, and discovering new things enthralled them.
