In this section, visitors can appreciate objects resulting from tribute, imposed through war, and from the trade the Mexicas maintained with various peoples, deposited in offerings for their symbolic value. Some regions were vital for the economic activity of the Mexicas, such as the obsidian deposits of the Sierra de las Navajas in the current Hidalgo state, and the Otumba area in Mexico State, mainly.

The exhibit also showcases pieces from the Mixtec region, such as greenstone figurines known as penates, primarily representing the god Tláloc. From Oaxaca, a collection of gold and silver jewelry is exhibited. Objects made of coral, shells, and worked conch originate from the Pacific Ocean, the Gulf of Mexico, and the Mexican Caribbean. A notable group of pieces from the Mezcala region in Guerrero state is also displayed, featuring masks, heads, and full-body human figures.

It is important to highlight that this section also displays objects from cultures preceding the Mexica, including Teotihuacan masks and an Olmec mask, the latter being the oldest object found at the Temple Mayor. These artifacts offer a glimpse into the recovery of the past, an essential activity for the Mexicas.
