With the mass deportations of the 2080s and the military patrols of their borders that were put in place during the Second Mexican-American War, animosity between the majority Mexican Southwestern States and the rest of the country began to grow and fester during the interwar period of the early 22nd Century. The Mexicanos Libres party formed out of this animosity and won majorities in most state governments in the region, while controlling the majority of congressional and senate seats from the Southwest as well. The MLP was normally seen as a regionalist party, not advocating secession, rather a degree of separation. A radical offshoot of the party was the Aztlan Autonomous Movement, which did seek to break off from the United States and form either an independent nation or rejoin Mexico. It was this movement that led the call for independence when Lionel Halvidar was elected President in 2132. The state governments of Arizona, New Mexico, Texas, and California, all with overwhelming majorities of citizens with Mexican ancestry, all voted to secede from the Union within months of Halvidar's election, forming the United States of Aztlan. The new country quickly established a presidency under the leadership of former Vice President of the United States, David Castillo, and broke up a number of larger states into smaller states that could be more fairly represented by the new government in Santa Fe.
The rebel states claimed that they owned all bases and other federal buildings in the Southwest, and ordered that US forces on the Mexican border be expelled from their territory. On 2 February 2133 the secessionists attacked the garrison at Camp Navajo in Arizona. Union forces from the border were diverted to defend the base, but after a 9 hour fight, the rebels accepted the surrender of the base commander, and the border guards were captured or picked off before they could return to their own garrisons. Following the attack, President Halvidar nationalized the national guards of the Union states, and called for a buildup of domestic military forces. Shortly after this call to arms was issued, three more southwestern states, and Panama joined with Aztlan instead of supplying forces to fight the rebels. The US Navy then organized a blockade of the California and Texas coastlines, and issued an ultimatum to Mexico and the Latin American Union, that any effort to support the rebels would be considered an act of war.
Despite this early showing of support, Aztlan quickly faced setbacks along its periphery. The National Guards of Oklahoma and Colorado remained loyal to the Union, while Eastern Texas subsequently seceded from Texas, joining the Union as the two new states of Brazos and Jacinto. By the end of 2133, Colorado and Oklahoma were effectively under Union control, with Aztlan state governments in exile. The US invaded the rebel states on February 22, 2133, moving through Northern California, Brazos, and Oklahoma. The US saw victories in the Aztlan state of Shasta and Northern Nevada rather quickly, retaking critical military targets, while forces in Texas found the Aztlan rebels more willing to fight than they'd expected. US Space Marines were deployed to support the Army in Texas and California and with momentum in New Mexico stalled, President Halvidar approved the use of orbital weapons on certain Aztlan targets. By the end of 2133, the rebel forces had been forced to relocate their capitol to Phoenix, Arizona. Utah, an autonomous state in Aztlan, went so far as to sue for a separate peace on May 11, 2134, allowing the US to surround the remaining Aztlan forces.
Mexico initially attempted to remain neutral, but militant elements within the Mexican government pushed to engage the US via proxy conflicts around the planet, to give the rebels a fighting chance. By the end of 2134 the US had successfully recaptured much of Texas and California, and were nearing the Aztlan capital in Phoenix. The conflict now threatened to spill across the border into Mexico, as northern Mexicans, many of whom were once US citizens, began actively supporting Aztlan's bid for independence. In some cases, Mexican volunteer regiments joined up with the Aztlan Army. At this point Deandre Garcia lost her bid for a second term in Mexico, and was replaced by the more radical Edwin Jaso's administration, which began quietly sending arms to the rebels. The Jaso administration began directly engaging the US across the planet, while supporting the Azlan rebels with weapons and intelligence. Some of the more radical rebels conducted public executions of all those who spoke out against the rebellion or stood in their war. This ultimately led to greater escalation in the conflict, as US forces were recalled from engagements in Africa and Eurasia to put down the rebellion at home.
For this scenario...What I can say: The Mexican state, illustrated here; is most stronge, organized, and stable. Many different of the corrupted, poor, divided, and pessimists. The mexican state illustrate here, is not the mexican state today. "logical" But is wonderful most incredible...upper full to vision closed of many people compatriots, so I can know...
The second war Mexican-American must be maturing to Mexico general mentality. This wonder I will feel great. Imagine the live in this time is incredible...and I hope will be most fair with the natives Mexican, farmers, pastors and all the people in my cuntrie what today suffer, injustice and discrimination in there in our land. Mmmm Because, the finance to milicians and the operations in a new countrie; borned in old land of a nation how USA, Is significative.
For other side; Aztlan, (The name of the City Legendary where the Aztec culture born The "Cuna" of Aztec culture), incluide in this territory, a big portion of all west coast; All California state. This is a big lost of territory, strategic power, political influence, and the most important in my opinion the Economic factor. The agriculture in this state is one of the most prosper of every USA, do not forgot the forests, and the minerals resources in all the south-west, a long the limits whit Mexico, the part of Texas under influence of Aztlan, there are citys and potitions importans for the nation of the bars and stars.
Most important now. The multiples military bases, and instalations and other proyects of this nature, after I watch the map, is increidible the little answer of the state American for not do it nothing for preserve this big portion of territory lost. But...how I say in the begin ot this comment;
Is the price for the discriminations zelop for people of Latin America and in general everyting world. Mmmm I need read more about yours maps and descitions of alternatives historys and posibilities scenarios.
Greath work!!! .
The immigration boom in the Southwest was partly the result of a series of reforms enacted by the US government in the early 2030s to streamline the immigration process to compensate for a labor shortage brought on by low birthrates in the US and the retirement of the Baby Boomer generation (which put additional stress on the economy by increasing the demand for health and elderly care services).
Mexico has grown in power over the last century of this timeline, partly thanks to its proximity to the US, but also due to its relationship with Latin America and access to both major oceans. Improvements to the economy and military responsibilities to South American necessitated political reforms, much as the US experienced in the 1940s.
Also, wouldn't a civil war in the US have massive economic repercussions for the whole world including Mexico?
Possibly Europe as well may have a similar problem with Muslim/Arabic populations having more children but that all seems to be tied to that fear monger Eurabia bullshit been spread by some rightwing lunatics like Anders Brevik so I don't exactly believe those sources.
Do the rebels have any weapons of mass destruction, like nukes or access to orbital weaponry?
Considering that Utah was autonomous within Aztlan, is Mormonism still around?
Mormonism is alive and well.
Also, wouldn't the southwest be as habitable as Crematoria by now, without water aid from the US gov?
