CONTEMPORARY PRINTING OF 1831 TREATY WITH MEXICOPrinted document, "Treaties with Mexico, May 1, 1832". Washington: Government Printing Office, 1834. 22nd Congress, 1st Session, House Document No. 225, signed in type by Andrew Jackson, with text in English and Spanish. The April 5, 1831 treaty, between the United States and the "United Mexican States" designated the border between the two countries as the mouth of the Sabine River at the Gulf of Mexico, which included the territory of Texas, thus reconfirming in 1831 that Texas was a Mexican property. The main text of the document refers to trading rules between Mexico and the United States, particularly in the case of rights for American citizens residing in Mexican Texas, in part: "...The citizens of the United States of America, residing in the United Mexican States, shall enjoy... the protection of the government...". The treaty is an interesting example of pre-war diplomacy; in 1831, the 30,000 Anglos living in Texas outnumbered the native Tejanos dramatically, and would soon go to war for the independence, spurred on in part by a desire to trade items that Mexico considered contraband. Bound with 19 other government documents from the 22nd Congress, including reports on fishing, finances, defense, and other topics pertinent to Jacksonian America. Of particular note is Document No. 121 from Secretary of War Lewis Cass, "Licenses to Trade with the Indians". Bound in calf and marbled boards with gilt lettering, some foxing, overall very good.
