Mora's administration had initiated a number of measures tending to the advancement of the country. Among other improvements was that of the fine national palace in San José. Costa Rica had enjoyed a long period of internal peace with an increasing prosperity. Mora was quite popular with the masses, but encountered opposition from the property owners, merchants, and army men. For this reason he could not strengthen his government, and found himself at the mercy of a coup de main the moment the people thought their interests were jeopardized by his power.[XVIII-7] Hence the revolutionary movement that hurled him from his executive office in the night of August 14, 1859. A provisional government, composed of his political enemies, was at once organized, meeting with no opposition on the part of the people. It was a palace revolution, and no blood was spilt. Mora was kept in confinement, though otherwise well treated during three days at the end of which he was taken to Puntarenas, and sent out of the country on an American steamer. He settled with his family in Salvador, where he introduced the cultivation of coffee. [Sidenote: VICENTE AGUILAR.] The new government now took steps to have itself confirmed by a constituent assembly, and to cause its provisional president, José María Montealegre, regularly elected. The influential man of the administration was Vicente Aguilar, ex-vice-president, a wealthy man, and the deadly enemy of Mora. He was the minister of the treasury and of war, and by his instigation some reactionary and despotic measures were adopted, thereby increasing the general uneasiness. The country was henceforth divided into two political parties, each claiming to be the representative of law and order.[XVIII-8] The constituent assembly, pursuant to convocation, met on the 16th of October, and on the 26th of December adopted a new constitution in 142 articles, which was promulgated the next day. This fundamental law was liberal except in the matter of religion, as it neither recognized nor tolerated any form of faith but the Roman catholic. All other rights of man were conceded.[XVIII-9] The constituent congress adjourned sine die on the 27th of December, and the ordinary congress opened its session on the 22d of April, 1860, on the next day declaring that José María Montealegre had obtained a popular majority for the office of president of the republic, and appointing the 29th for his inauguration. On the 24th that body designated the persons who were to fill the executive chair in the temporary or absolute absence of the president.[XVIII-10] [Sidenote: DEATH OF MORA.]
