it was big
We have no evidence of a Anasazi empire. The Anasazi started leaving the area they were in for the south and east in the mid 1200s.
No, there were no horses, donkeys, or mules in the Americas when the Anasazi existed as a group (named by the Navajo who were new arrivals and at war with them), The Anasazi abandoned their large cliff dwelling due to climate shift, and it is believed their modern descendants are the Hopi and other Pueblo tribes still living in the area. They never referred to themselves as "Anasazi"!
It is necessary to have a strong military force with a large empire.

The Persian Empire.
The Anasazi.
The large Inca Empire was connected by 10,000 miles of paved roads.
The Anasazi and the Incas were both ancient civilizations that developed advanced agricultural techniques, had complex social structures, and constructed impressive architectural feats like cliff dwellings and stone cities. They both also mysteriously disappeared, with the Anasazi abandoning their settlements in the 13th century and the Inca Empire falling to the Spanish conquistadors in the 16th century.
