A period of constant revolutionary ferment and frequent changes of the constitution followed, with a wearisome succession of military presidents. General Ignacio Maria Gonzalez became provisional president in 1874, took advantage of the non-payment of an annuity by the Samana Bay Company to rescind the contract with the company, called a national assembly, which formulated the constitution of March 24, 1874, and had himself elected president, entering upon office on April 6 of that year. As the constitution did not suit him, he called a new national convention and had another constitution promulgated on March 9, 1875. This was too much even for Santo Domingo, and his enemies formed a powerful league in Santiago with a view to having him impeached, but the Congress rejected the charges. Another civil war was imminent when Gonzalez resigned on February 23, 1876. The council of ministers took charge of the government and held an election at which Ulises F. Espaillat was designated president. He entered upon office on April 29, 1876, and as he was an excellent man would have given a good account of himself under different conditions; but General Gonzalez started a revolution on the Haitian frontier, and on October 5, 1876, Espaillat was ousted. A superior council of government was formed, which appointed General Gonzalez president in the beginning of November, 1876. Gonzalez had been in power for just one month when he was overthrown, in December, 1876, by a revolution that originated in the Cibao, and General Buenaventura Baez became president for the fifth time. The Republic thus had four presidents in 1876: Gonzalez twice, Espaillat and Baez. Baez called a constitutional convention and the constitution of May 14, 1877, was promulgated. Under the influence of the younger element he was less autocratic than in his previous administrations, but perhaps for that very reason his whole term was one prolonged struggle with insurrections, until he was obliged to surrender on February 24, 1878. He retired to Porto Rico and died near Mayaguez in 1884. Two governments were now established, General Ignacio Maria Gonzalez being proclaimed president in the Cibao, and General Cesareo Guillermo in Santo Domingo. An agreement was reached by them on April 13, 1878, and Guillermo became provisional president of the entire country. The constitution of 1877 was reproclaimed with amendments, an election was held and General Gonzalez was declared constitutional president, entering upon office on July 6, 1878. Guillermo immediately started a revolution with General Ulises Heureaux and compelled Gonzalez to abdicate on September 2, 1878. It was the end of Gonzalez' meteoric presidential flights, but after a period of retirement he ventured into public life again, and for many years was Dominican minister to Haiti.
