Mexico and Central America 979 CE
The Mayan civilization is now in decline.
What is happening in Mexico and Central America in 979CE
In the Valley of Mexico, the Toltec have established their dominance. Their capital, Tula, whilst not matching Teotihuacan in size, has nevertheless grown to be a very large city. Like the people of Teotihuacan before them, the Toltec exercise a widespread influence – and perhaps a measure of military dominance – throughout Mesoamerica. The memory of Tula will have a deep influence upon the imagination and beliefs of the later Aztec people.
In the 9th century many Mayan city-states experienced a sudden collapse in population, while others went into steady decline; many of the historic cities of the Yucatan lowlands now lie abandoned. This may have been due to environmental decline, probably the result of an unsustainable level of population density.
In the north of the Yucatan Peninsula other Mayan cities continue to flourish. Uxmal rose to control a large territory in the 9th century, but its power has recently been eclipsed by that of Chichen Itza. The latter evidently has close links with Tula, in the Valley of Mexico.
