Heureaux was able to strengthen himself to such an extent that when, in 1882, Luperon determined to become president himself he found that his former follower had outgrown him in power. The result was that Heureaux became president and served from September 1, 1882, to September 1, 1884. When his term expired a bitter struggle ensued with Luperon, who still retained considerable influence. Luperon's candidate was Segundo Imbert, while Heureaux supported General Francisco Gregorio Billini, who was ultimately victorious. Luperon went into exile, but later became reconciled with Heureaux and returned to die in Santo Domingo. Billini entered upon the presidency on September 1, 1884, but became restive under the demands of Heureaux and his friends and resigned on May 15, 1885. The vice-president, Alejandro Woss y Gil, succeeded to the chief office. His term was to have expired in September of the following year, but a formidable insurrection broke out in July, 1886, under General Casimiro N. de Moya, with the object of preventing Heureaux from carrying out his design of succeeding Gil. After six months of fighting, during which the number of fatalities was happily remarkably small, Heureaux was victorious, and having had himself re-elected, resumed the presidency on January 6, 1887, until which time Woss y Gil remained in office. The biennial elections were a source of annoyance even to one who was sure of victory, and Heureaux therefore called a constitutional convention which amended the constitution then in force and lengthened the presidential term to four years, beginning in 1889. As General Cesareo Guillermo, Heureaux's former companion in arms and later opponent, was understood to be nursing aspirations for the presidency, Heureaux sought to apprehend him. Guillermo fled, but finding himself pressed, committed suicide. No further obstacle opposed Heureaux's election, and he was again inaugurated on February 27, 1889. In the meantime negotiations had been undertaken for the contracting of new foreign loans, and one was floated in 1888 and another in 1892. The government's fiscal agent who secured these loans in Europe was General Eugenio Generoso Marchena, a man of much influence. In 1892 General Marchena announced himself as a candidate for the presidency. Heureaux won without difficulty, but still uneasy, he arrested Marchena in Santo Domingo, imprisoned him for a year and sent him to Azua to be shot.
