506 years ago today, on April 21, 1519 (March 23, 1519, the 1519 lunar calendar), a fleet led by Spanish colonist Hernando Cortis landed in Mexico. On April 21, 1519, the Spanish nobleman Hernando Cortis (1485-1547), led about 600 infantry and 200 Indians, carrying 10 cannons, 16 war horses, and 11 ships, landed on Veracruz on the east coast of Mexico to launch an attack on the country of the Asteks. King Montezuma II (1475-1520) sent a large amount of gold, silver and jewelry to Cortis, requesting the withdrawal of the troops. Cortiz tried his best to sow discord and formed alliances with many tribes dissatisfied with Montezuma and entered Mexico City in November. Not only did Montezuma not resist, but instead personally hosted a grand welcome ceremony and welcomed Cortis into the palace. Cortis planned the arrest of Montezuma and imposed rule in his name, extorting gold, silver and jewelry. In June 1520, the Indians rose up, and Cortez and his gang fled in panic in the night rain. Countless people were killed and fell into the lake and drowned. The stolen treasure fell into the bottom of the lake. This was the famous "Sorrow Night." In August 1521, Cortiz led his troops to invade Mexico City again and turned Mexico into a Spanish colony, calling it "New Spain." 1523-1524 In 1977, the Spaniards invaded Guatemala, Honduras, Nicaragua and El Salvador.
