Pedro de Alvarado was born in 1485 to a family both wealthy and militaristic. Little is known for certain about his youth, and to be frank it matters even less, for Alvarado was truly "born" in 1518, when he set out on his first expedition with Juan de Grijalva, nephew of the explorer Francisco Hernandez de Cordoba.
The Spanish left Cuba in April, and sailed the coasts of Yucatan. On their trip, they saw three large Maya cities, and later took revenge for the defeat of the Spanish expedition led by Hernandez. Five months after leaving, he returned. This was not a trip of immense importance, but its consequences would be.
That is, because of the reports of riches, a new fleet was organized, led by Hernan Cortes - later known as the Gran Conquistador. On this fleet was, again, Pedro de Alvarado. They anchored at a Maya town and quickly took it with their horses and firearms. Here, Hernan was to meet his lifelong consort, Malintzin, also known by the Christianized name "Marina". From thereon out, Cortes continued through the Aztec Empire. Due to the relations between the Spaniards and the natives being uneasy, the Spaniards took Montezuma as their hostage. Cortes soon had to leave, however, because of another expedition that was hostile to his cause. Alvarado was left in command.
This proved to become a disaster: one night, the Aztecs held a religious festival called Toxcatl, dedicated to Tezcatlipoca. In the course of the festival, the young man who had been the god's host for a year was sacrificed, as well as some others. This festival regularly attracted the attention of all the other gods, and this year moreso because the Spaniards were in attendance. Tonatiuh, in particular, took an interest in the blond-haired Alvarado and infected him. To celebrate his new host, he ordered his men to massacre the Aztecs present and baptize his new body in their blood; after all, sooner or later it would be his anyway.
Still, in the process, the king too was killed and relations soured. When Cortes returned, the men escaped a few weeks later, during the events of La Noche Triste ("the night of sorrows"), taking as much gold as they could carry and fighting their way out of Tenochtitlan.
At length, the forces under Cortes later managed to take Tenochtitlan after a long and bloody siege in 1521, helped by their native allies who desired to rid themselves of Aztec domination. Alvarado then became the leader of the efforts to conquer Guatemala, and accomplished this with his usual violent strategies, including taking unsuspecting hostages, massacring the populace, and burning their cities. All the while, he enriched himself, declaring war when the natives would not pay up their tributes. In essence, he was still practicing human sacrifices, although this time in the name of almighty gold. For this campaign, he was later accused of excessive brutality. On the other hand, he received a governorship for this very same territory, and remained so until his death.
In 1541, he died in a "freak accident" when Tonatiuh was bored of him, moving on to a new host in an attempt to resist the end of the Aztec Mysteries. Needless to say, this proved fruitless; no matter the amount of blood shed in his name, the age of the Fifth Sun was never coming back.
