What was the first area time conquered

The overseas expansion under the Crown of Castile was initiated under the royal authority and first accomplished by the Spanish conquistadors. The Americas were invaded and incorporated into the Spanish Empire, with the exception of Brazil, Canada, the north-eastern United States and several other small countries in South America and The Caribbean. The crown created civil and religious structures to administer the region. The motivations for colonial expansion were trade and the spread of the Catholic faith through indigenous forced conversions.
