Mariano Paredes confronted the same situation in 1846.
And in 1847, Santa Anna would face the constant suspicion of treason, which prevented him from establishing direct contact with Nicholas Trist after the Cerro Gordo defeat.
Thus, all confronted opposition forces that questioned their legitimacy and were eager to overthrow them.As a result of these conditions, the problems of the separation of Texas and its annexation to the United States, as well as John Slidell's mission, became part of the debate among political parties and factions and a pretext for one faction or another to downplay the legitimacy of its opponents.But there are few who have the boldness to express these opinions publicly, or who [would] be willing to stem the current popular prejudice by undertaking to carry them out."2 It is also worth emphasizing here that constitutional changes made during this period imposed restrictions on the actions of those in power.Some examples include: an article added to the constitution prohibiting the transfer of control over territory;3 and amendments to the 1824 Federal Constitution which were approved in 1847 and which disqualified "the Executive from signing a peace agreement and concluding negotiations with foreign nations." 4 From the Mexican perspective, there were two facets to the problem of Texas: one was related to its separation from Mexico and the other to its annexation to the United States.Faced with this situation, the José Joaquín de Herrera administration attempted a double-edged diplomacy by, first, denouncing the U. Congressional resolution as illegal,6 and secondly, establishing negotiations with Texas with two objectives in mind: to avoid the annexation of Texas and elude an armed conflict with the United States.
