Where did the European expolores that visted Colorado come from?

European explorers who visited Colorado primarily came from Spain and France. Spanish explorers, such as Francisco Vázquez de Coronado in the 1540s, were among the first Europeans to venture into the region, seeking gold and new territories. Later, French explorers, including those associated with the Louisiana Purchase, also explored the area in the 18th century as they sought to expand their influence in North America.
