During the elections a bloodless revolt of four regiments simultaneously occurred, on the 7th of June, 1846, at San José, Cartago, Heredia, and Alajuela, to overthrow the organic law. The movement was seconded at once by the people,[XI-54] and José María Alfaro was summoned to assume the reins of government, Gallegos returning to the presidency of the senate. Every one recognized Gallegos as an upright man, against whom no complaint was made.[XI-55] Alfaro accepted the rôle, went into office on the 9th, and immediately proceeded to carry out the purposes of the revolution. Elections took place under the existing constitution, Alfaro being chosen jefe, and José M. Castro vice-jefe and secretary-general. The latter being the intellectual superior of Alfaro, every branch of the administration finally fell under his control. The constituent assembly met on the 15th of September, and completed, on the 21st of January, 1847, the new constitution, which was promulgated at once, to have effect from and after the 7th of March.[XI-56] Experience having shown that several clauses of this instrument were practically inexpedient, and that others were not clearly worded, under article 187 of the same congress subsequently adopted a number of amendments, which had been asked for by a majority of the municipalities.[XI-57] The elections for supreme authorities, decreed on the 17th of February, took place; the constitutional congress assembled on the 1st of May, and after counting the votes for president and vice-president on the 5th, declared Castro duly elected for the first position and Alfaro for the second. They were inducted into office on the 8th.[XI-58] Castro's administration had to overcome serious obstacles which might bring on political convulsions in the near future.[XI-59] Indeed, several disturbances broke out at Alajuela, headed by Alfaro and his friends, which were, however, easily quelled by President Castro, and once by Vice-president Mora, when the president was absent.[XI-60] The last of these troubles caused some bloodshed.[XI-61] Albeit the revolts were put down, the state continued much agitated. Inflammatory writings against the president were secretly circulated, which the government gave importance to, and the official press tried to counteract their influence. Castro concluded to resign his office, but congress by a unanimous vote refused to accept the resignation.[XI-62] Costa Rica having by the act of her congress, on the 30th of August, 1848, declared herself a sovereign and independent nation, under the title of República de Costa Rica, that body, on the 29th of the following September, adopted a flag, coat of arms, and seal.[XI-63] [Sidenote: INDEPENDENCE DECLARED.] [Illustration: ARMS OF COSTA RICA.]
