Concept:The Spanish conquistador Hernán Cortés led the expedition that conquered the Aztec Empire in modern-day Mexico.
Explanation:The correct explorer who conquered Mexico is Hernán Cortés.
Cortés landed on the coast of Mexico in 1519 with a small army of conquistadors.
He formed alliances with native groups like the Totonacs, who wanted to break free from Aztec rule.
The Aztec emperor Montezuma II initially believed Cortés might be a returning god and sent gifts.
Cortés and his forces eventually captured Tenochtitlan (the Aztec capital) in 1521 after a brutal siege.
This conquest, called the Spanish–Aztec War, led to three centuries of Spanish colonial rule.
The other options are incorrect for the following reasons:
Vasco da Gama was a Portuguese explorer who reached India by sea around Africa in 1498.
Bartholomew Diaz was also a Portuguese explorer who first sailed around the southern tip of Africa in 1488.
Ferdinand Magellan led the first expedition to circumnavigate the globe, but he died in the Philippines and did not conquer Mexico.
