Mexican War of Independence
Although Mexico gained its independence in September 1821, the marking of this historical event did not take hold immediately. The choice of date to celebrate was problematic, because Iturbide, who achieved independence from Spain, was rapidly created Emperor of Mexico. His short-lived reign from 1821–22 ended when he was forced by the military to abdicate. This was a rocky start for the new nation, which made celebrating independence on the anniversary of Iturbide's Army of the Three Guarantees marching into Mexico City in triumph a less than perfect day for those who had opposed him. Celebrations of independence during his reign were marked on September 27. Following his ouster, there were calls to commemorate Mexican independence along the lines that the United States celebrated in grand style its Independence Day on July 4. The creation of a committee of powerful men to mark independence celebrations, the "Junta Patriótica", organized celebrations of both September 16, to commemorate Hidalgo's grito and the start of the independence insurgency, and September 27, to celebrate actual political independence.
American-Mexican Claims Commission
Since Mexico's independence in 1821, the US and Mexico on a number of occasions had disputes over territory, taxation, and claims by US private citizens. Claims between 1825 and 1839 were arbitrated by a claims convention, on the suggestion of the Mexican government. The convention was established on April 11, 1839. Subsequent commissions were constituted in 1839, following the Texas Revolt and claims following the Treaty of Guadalupe Hidalgo (1848), the Gadsden Treaty (1854), and the McLane-Ocampo Treaty (1859). A commission was set up following the expulsion of the French in 1867, which was constituted on July 4, 1868.
The Commission was constituted under the terms of the General Claims Convention, signed September 8, 1923, in Washington D.C. by the United States and the Mexico, during the administration of Mexican President Alvaro Obregón and U.S. President Calvin Coolidge (succeeding Warren G. Harding who died just a month earlier.) Obregón had sought U.S. diplomatic recognition for his government and engaged in bi-lateral talks with the U.S. over constitutional issues regarding oil, resulting in the Bucareli Treaty. The Mexican-U.S. General Claims Commission was another formal effort to renegotiate the relationship between the Mexico and the U.S. The convention, which took effect on March 1, 1924, was intended to improve relations between the countries by forming a commission to settle claims arising after July 4, 1868,“against one government by nationals of the other for losses or damages suffered by such nationals or their properties” and “for losses or damages originating from acts of officials or others acting for either government and resulting in injustice.” Excluded from the jurisdiction of the General Claims Commission were cases stemming from events related to revolutions or disturbed conditions in Mexico.
