The better elements of the triumphant party were not able to keep the upper hand. A new Constitution was hastily adopted and the mulatto Ramon Roca installed as president. For four years he ruled while the gulf between liberals and conservatives widened day by day, and factional jealousies and ambitions within the dominant party became menacing. The congress of 1849 quarrelled bitterly over the presidential succession and was unable to agree on any one. Ambitious chiefs got arms and men together, and after a year of uncertainty General Urbina, of Guayaquil, issued a pronunciamento declaring Diego Noboa provisional head of the government. A convention called for the purpose adopted a new Constitution and elected Urbina's nominee president for the full term. To the consternation of the liberals he recalled the Jesuits and gave asylum to the defeated conservatives from Colombia, going so far as to send troops to the frontier to aid in their restoration. But Urbina, to whose command these forces had been entrusted, proclaimed himself dictator and exiled Noboa. He promulgated a new Constitution--Ecuador's sixth in twenty-two years,--persecuted the conservatives, and ruled for four years as an ultra-liberal. At the expiration of his term in 1856 he named his friend Robles as his successor, who maintained himself against the conservative attacks until in 1859 his government became involved in a war with Peru. When Robles and Urbina went to the Peruvian frontier the conservatives rose behind them. As a matter of fact the country was tired of the misrule of the military chiefs, miscalled liberals, whose government was a compound of oppression for their enemies and license for their friends. The clericals armed their adherents in the northern villages and marched on Quito. The partisans of the administration at the capital could oppose no effective resistance, and the insurgents entered the city, and on May 1st installed a provisional government with Garcia Moreno at its head. The latter at once pushed on south with a small force, and, though defeated by Robles, he escaped to Peru, where he received help for new operations. In spite of Moreno's temporary reverse his friends retained possession of Quito, and the Peruvian blockade of Guayaquil absorbed the president's attention. The forces under Robles soon crumbled away, and he resigned and went into banishment. Urbina, the real chief of the liberal party, had a small body of troops in Cuenca with which he tried to maintain the unequal contest, but his position soon became untenable and he followed Robles into exile.
