[2] After this, the Dominican Republic would have to fend off against external interests from Haiti, Spain, France, Great Britain, and the United States to maintain its sovereignty.

Internally, the new nation faced a series of challenges, including the construction of a stable political system and the organization of the state structure.

However, the nation for much of the period operated under the rule of conservative cuadillos, who sought out to disburse the liberal principles that laid the foundation of the patriotic sentiment.

The first Republic was also a de facto French protectorate, the Junta Gubernativa declared it the Protectorate of Dominican Republic On the night of February 27, 1844, the leaders of the Triniatrios were going to make their dreams come true: to not only free the Dominicans from Haitian control, but to established an independent state free from all foreign power.

At dawn, the blunderbuss shot of Matías Ramón Mella rang out at the Puerta de la Misericordia, and thus, the Dominican Republic was born.

During the period called The First Republic (1844-1861), the Haitians tried on numerous occasions to regain control over the Dominican part of the island, but were defeated time and again by Creole forces.

The decision of the vast majority of Dominicans to be free and independent, the fight in their own territory, generally from more advantageous positions, the use of pack animals for transport and combat, while the Haitians marched on foot and did not receive support of food, medicine and other supplies from their country when they were on campaign; They were factors that contributed to militarily consolidating the independence from Haiti.

Through majority control, the presidency of the Central Government Board was in the hands of Tomás Bobadilla, and the Liberation Army with General Pedro Santana, and his Seiban lancers.

Although they were the ones who had the experience in managing men for the coming war, they were also allies of the bourgeoisie of foreign importers and exporters who supported the annexation of the country to the highest power.

After a failed attempt by the petty bourgeoisie to regain power under the leadership of Juan Pablo Duarte, who represented the strongest component opposed to the imposition of foreign rule, the hatero sector led by Santana, leader of the East of the country, expelled the Trinitarios and established a military dictatorship, which was only disputed by his former protégé, Buenaventura Báez, a rancher-logger and merchant from the South, more educated and better administrator, although more cunning end even honest than Santana.

In addition, his economic policy favored large landowners and harmed small farmers and workers These unpopular measures and the lack of legitimacy of Santana's government contributed to the worsening of the political crisis in the First Dominican Republic.

The revolutionaries placed the Baecistas around Santo Domingo, proclaimed a liberal constitution and moved the capital to Santiago, but they accepted the return of Santana and put him in command of the besieging troops.

Deposits of gold and silver were discovered in some regions of the country, which attracted miners and businessmen interested in exploiting these resources.
