Explanation:

Ferdinand Magellan was a Portuguese navigator who, at the service of the King of Spain, commanded the sea expedition that made the first sea voyage around the globe. He was the first navigator to reach Tierra del Fuego in the extreme south of the American continent, crossed the Strait of Magellan and crossed the Pacific Ocean, which he named in this way, for its calm waters. In addition to these achievements, he became known for starting violent conflicts with the indigenous population of the continent.

Another one who fought intense and violent battles with American Indians was Hernan Cortes.

Hernán Cortez was a Spanish explorer and conqueror born in the city of Medellín, in the then kingdom of Castile. He is famous for his achievement of the Aztec Civilization. The son of a decadent nobleman, Cortez studied at the University of Salamanca, but did not complete his studies. At the age of 19, he left his native kingdom and traveled by ship to the island of Hispaniola, in the current region of the Antilles, where he started to work as a clerk and farmer until, a few years later, he met the conqueror Diego Velázquez de Cuellar, future governor of Cuba, which employed him in military tasks involving the conquest of the island. As a reward for his service, Cortez became mayor of the city of Santiago. Later, he would also marry a relative of Velásquez.
