Where did Spain's great wealth came from .?

Spain's great wealth during the 16th and 17th centuries primarily stemmed from its vast colonial empire in the Americas. The influx of gold and silver, particularly from mines in present-day Mexico and Bolivia, significantly enriched the Spanish crown. Additionally, agricultural products and resources from colonies, along with trade monopolies and tariffs, further bolstered Spain's economy. However, this wealth also led to economic challenges, including inflation and overreliance on precious metals.
