This collection begins with an original manuscript from the era of the Spanish conquest in Spanish America in 1546. Two hundred and fifty years later, there follows a manuscript papal document (Pius VI) with tables of the church's revenues and additional documentation from the government in Mexico. There is a Royal decree from Charles IV, and proclamations from Viceroys, Commandants and the Emperor Augustin Iturbide. The chronological progression illustrates Mexico's declaration of independence from Spain, a treaty between Spain and the U. S. regarding Texas, the fundamental law of Texas statehood as a part of Mexico, and numerous proclamations related to Texas' struggle for independence from Mexico. There is a collection of possible itineraries for General Woll's invasion of Texas dated 1844, and other evidence of the preparation for war over Texas a year prior to the outbreak of the Mexican-American War. The final exhibit is an engraving of Antonio Lopez de Santa Anna in a cartouche made up of an elaborate list of titles and victories in battle.
