The state seemed at relative calm compared to the rest of the country due to its close ties to the United States until 1841. In 1843 the possibility of war was anticipated by the state government and it began to reinforce the defense lines along the political boundary with Texas. Supplies of weapons were sent to fully equip the military and took steps to improve efficiency at the presidios. Later, the Regimen for the Defenders of the Border were organized by the state which were made up of: light cavalry, four squads of two brigades, and a small force of 14 men and 42 officials at the price of 160,603 pesos per year. During the beginning of the 1840s, private citizens took it upon themselves to stop the commercial caravans of supplies from the United States, but being so far away from the large suppliers in central Mexico the caravan was allowed to continue in March 1844. Continuing to anticipate a war, the state legislature on July 11, 1846 by decree enlisted 6,000 men to serve along the border; during that time Ángel Trías quickly rose to power by portraying zealous anti-American rhetoric. Trías took the opportunity to dedicate important state resources to gain economic concessions from the people and loans from many municipalities in preparation to defend the state; he used all the money he received to equip and organize a large volunteer militia. Ángel Trías took measures for state self-dependence in regards to state militia due to the diminishing financial support from the federal government.
