A king lived long ago. 

A king named Ahuitzotl ruled long ago. 

Ahuitzotl was a great Aztec ruler. He ruled the city of Tenochtitlan. His name meant "Water Thorny." This was also the name of an animal. 

Ahuitzotl was a powerful leader of the Aztec people. He ruled from the great city of Tenochtitlan. His name means "Water Thorny." This name came from a legendary animal. Some think the animal was an otter. Others think it was a water opossum. 

Ahuitzotl became the ruler in the year 1486. This was the year 7 Rabbit. He took power after his brother Tizoc died. He was the son of Princess Atotoztli II. Ahuitzotl worked hard to grow his empire. He first stopped a rebellion by the Huastec people. Then he led many more wars to win new lands. He more than doubled the size of the Aztec domain. 
His conquests covered a huge amount of land. He moved through many different areas. He conquered the Mixtec and the Zapotec peoples. His empire reached from the Pacific Coast of Mexico. It went all the way to western Guatemala. This made the Aztec lands much larger than before. He helped make the empire very strong. 
Ahuitzotl was also a great builder. In the year 1487, he began a big project. This was the year 8 Reed. He expanded the Great Pyramid of Tenochtitlan. This pyramid is known as the Templo Mayor. He also helped move a new bird to the area. This bird is the great-tailed grackle. This was the first time humans moved a bird in the Western Hemisphere. 
Ahuitzotl had two sons named Chimalpilli II and Cuauhtémoc. He also had one daughter. He ruled for many years until 1502. This was the year 10 Rabbit. His nephew, Moctezuma II, became the next ruler. People still remember him in Mexico City today. A bronze statue of him stands in Gustavo A. Madero. This statue was first made for the 1889 Paris Exposition. 
Ahuitzotl was the eighth ruler of the Aztec people. He served as the Huey Tlatoani of Tenochtitlan. This title means "supreme tlatoani." It was used to show superiority over other cities in the Triple Alliance. The Triple Alliance was the group of cities that formed the Aztec Empire. Ahuitzotl was the son of Princess Atotoztli II. His name literally means "Water Thorny." This name came from a legendary creature called an ahuitzotl. Some people think this creature was an otter. Others believe it was a water opossum. A water opossum has a prehensile tail, which means it can grasp things. Otters do not have this kind of tail.
Ahuitzotl took power in the year 1486. This was known as the year 7 Rabbit. He became emperor after his brother, Tizoc, died. Ahuitzotl was a very important military leader in pre-Columbian Mesoamerica. He began his reign by suppressing a rebellion by the Huastec people. After that, he worked to expand the Mexica domain. He was very successful at growing the empire. He more than doubled the size of the lands under Aztec control. 
The expansion of the empire reached many different groups of people. Ahuitzotl conquered the Mixtec and the Zapotec peoples. His military campaigns moved across a huge area of land. The empire reached from the Pacific Coast of Mexico. It extended all the way to the western part of Guatemala. This massive growth consolidated the power of the Aztec Empire. It made the empire much larger than it had been under previous leaders. 
Ahuitzotl was not only a conqueror but also a great builder. He supervised a major rebuilding of the city of Tenochtitlan. He wanted the city to be on a much grander scale. In the year 1487, which was the year 8 Reed, he expanded the Great Pyramid. This pyramid is called the Templo Mayor. This project helped show the strength and importance of his capital city. His work changed the physical look of the Aztec center.
During his reign, Ahuitzotl also oversaw a unique biological event. He presided over the introduction of the great-tailed grackle to the Valley of Mexico. This is the earliest documented case of human-mediated bird introduction in the Western Hemisphere. Human-mediated introduction means that people moved the animal to a new place. This bird became a part of the local environment because of these actions. It shows how the ruler's influence reached even the natural world.
Ahuitzotl had a family that included two sons and one daughter. His sons were named Chimalpilli II and Cuauhtémoc. He ruled for many years until his death in 1502. This was the year 10 Rabbit. After he died, his nephew Moctezuma II became the next ruler. Ahuitzotl's long reign helped shape the future of the Aztec leaders who followed him. 
Today, the legacy of Ahuitzotl is still visible in art. He is commemorated alongside his grandson, Itzcoatl. They are honored by a bronze statue in the Monumento a los Indios Verdes. This monument is located in Gustavo A. Madero, Mexico City. The statues were originally created for the 1889 Paris Exposition. This shows that people in Europe were interested in Aztec history long ago. 
Ahuitzotl also appears in various forms of modern storytelling. He is a character in the Obsidian and Blood book series by Aliette de Bodard. In those stories, he is called Teomitl. He is also a prominent character in the historical fiction novel titled Aztec by Gary Jennings. That book describes his wars of conquest and his building projects. These stories look at the time just before the Spanish Conquistadors arrived. They help people imagine the complex world Ahuitzotl helped build.
