The Aztecs.
The European explorer who destroyed the Aztec civilization was Hernán Cortés. In 1519, he led an expedition that ultimately resulted in the conquest of the Aztec Empire in present-day Mexico. Cortés and his forces, aided by indigenous allies, captured Tenochtitlán in 1521, leading to the fall of the Aztec civilization and significant changes to the region's society and culture.
Leave? Spaniards didn't leave Aztecs alone; they conquered them and utterly destroyed their civilization.
The Aztec civilization, led by Emperor Moctezuma, was conquered and destroyed by Hernan Cortes and his Spanish forces in the early 16th century. Cortes arrived in Mexico in 1519 and, with the help of indigenous allies who resented Aztec rule, he was able to defeat the Aztec Empire in 1521.
It was not just one European, it was the Spanish Conquistadors lead by Cortes.
