Who is the Conquistador that claimed most of Central America for Spain?

The Conquistador who claimed most of Central America for Spain was Hernán Cortés. He is best known for his expedition that led to the fall of the Aztec Empire in Mexico, but his conquests also extended into regions that are now part of Central America, including present-day Guatemala and Honduras. His explorations and conquests significantly expanded Spanish territory in the region during the early 16th century.
