I regret to inform you that there has been no improvement in the affairs of Mexico since my last annual message, and I am again obliged to ask the earnest attention of Congress to the unhappy condition of that Republic. The constituent Congress of Mexico, which adjourned on the 17th February, 1857, adopted a constitution and provided for a popular election. This took place in the following July (1857), and General Comonfort was chosen President almost without opposition. At the same election a new Congress was chosen, whose first session commenced on the 16th of September (1857). By the constitution of 1857 the Presidential term was to begin on the 1st of December (1857) and continue for four years. On that day General Comonfort appeared before the assembled Congress in the City of Mexico, took the oath to support the new constitution, and was duly inaugurated as President. Within a month afterwards he had been driven from the capital and a military rebellion had assigned the supreme power of the Republic to General Zuloaga. The constitution provided that in the absence of the President his office should devolve upon the chief justice of the supreme court; and General Comonfort having left the country, this functionary, General Juarez, proceeded to form at Guanajuato a constitutional Government. Before this was officially known, however, at the capital the Government of Zuloaga had been recognized by the entire diplomatic corps, including the minister of the United States, as the _de facto_ Government of Mexico. The constitutional President, nevertheless, maintained his position with firmness, and was soon established, with his cabinet, at Vera Cruz. Meanwhile the Government of Zuloaga was earnestly resisted in many parts of the Republic, and even in the capital, a portion of the army having pronounced against it, its functions were declared terminated, and an assembly of citizens was invited for the choice of a new President. This assembly elected General Miramon, but that officer repudiated the plan under which he was chosen, and Zuloaga was thus restored to his previous position. He assumed it, however, only to withdraw from it; and Miramon, having become by his appointment "President substitute," continues with that title at the head of the insurgent party.
