The Mexican-North American War, also known as the First North American War, was an armed conflict in Mexico that occurred from October 2064 to June 2065. It occurred when Northern Mexican states held referendums over integration into the newly formed North American Union. All states that held referendums voted in favour of joining the union, however the Mexican government did not recognize the referendums and still recognized the seceded states as part of Mexico, deploying soldiers in the region. The government of the North American Union decided that military action was necessary "for the interests of Mexicans" and deployed North American soldiers throughout the states. North American forces gained control of the states which held referendums on June 13, 1965 and signed a peace treaty wit
