The Dominican War of Independence (Spanish: Guerra de Independencia Dominicana) was a war of independence that began when the Dominican Republic declared independence from the Republic of Haiti on February 27, 1844 and ended on January 24, 1856. Before the war, the island of Hispaniola had been united for 22 years when the newly independent nation, previously known as the Captaincy General of Santo Domingo, was unified with the Republic of Haiti in 1822. The criollo class within the country overthrew the Spanish crown in 1821 before unifying with Haiti a year later.
In March 1844, 30,000 Haitian soldiers invaded the Dominican Republic at the behest of president Charles Rivière-Hérard, but were defeated within a month and forced to retreat back into Haiti. The Haitian campaign of 1845 ended with the retreat of the Haitian army across the Dajabón River. Three years later, Haiti's president Faustin Soulouque launched his first invasion of the Dominican Republic, but his army was beaten back by forces under General Pedro Santana. In late 1849, Dominican naval forces bombarded, sacked and burned several villages on the southern and western coasts of Haiti. In November 1855, Soulouque marched into the Dominican Republic at the head of another army, but the Haitians were decisively defeated and forced back across the border by January 1856.
Background
In the late 18th century, the island of Hispaniola had been divided into two European colonies: Saint-Domingue in the west, governed by France; and Santo Domingo in the east, governed by Spain, occupying two-thirds of Hispaniola. By the 1790s, large-scale slave rebellions erupted in the western portion of the island, which led to the eventual removal of the French and the independence of Haiti in 1804. Following the independence of Haiti, massive portions of the remaining French population were murdered. The eastern portion of the island was preparing itself for an eventual separation from Spain.

These divisions would later evolve into Haiti and the Dominican Republic as we know them today. Edwards further identifies the Mountains of Cibao, where Columbus famously sought for gold.
At the beginning of the 1800s, the colony of Santo Domingo, which had once been the headquarters of Spanish power in the New World centuries prior, was suffering an economic decline. Spain during this time was embroiled in the Peninsular War with Napoleon in Europe, and other various wars to maintain control of the Americas. With Spain's resources spread among its larger colonies, its Caribbean territories became relatively neglected. This period is referred to as the España Boba era. The island was suffering economically as the island had been damaged from wars against France.
The Captaincy General of Santo Domingo had approximately 80,000 inhabitants, with the majority being European descendants and mulattos. For most of its history Santo Domingo had an economy based on mining and cattle ranching. The population in the Spanish colony was significantly lower than the French side of the island, which had a population of nearly one million slaves before the Haitian Revolution.

Santo Domingo was regionally divided with many rival and competing provincial leaders. During this period in time the Spanish crown wielded little to no influence in the colony. Some wealthy cattle ranchers had become rulers, and sought to bring control and order in the southeast of the colony where the "law of machete" ruled the land. On November 9, 1821 the former Captain general in charge of the colony, José Núñez de Cáceres, influenced by all the Revolutions that were going on around him, finally decided to overthrow the Spanish government and declared independence from Spanish rule, this would usher in an Ephemeral Independence.
Unification of Hispaniola (1822–1844)

A group of Dominican politicians and military officers in the frontier region had expressed interest in uniting the entire island, while they sought power with military support from Haitian officials against their enemies.
Haiti's president, Jean-Pierre Boyer, a mulatto who was seen as an ally promised his full support to the frontier governors, and thus he ceremonially entered the country with around 10,000 soldiers in February 1822, after most of the cities and towns proclaimed their allegiance to Boyer between November 1821 and January 1822. On February 9, 1822, Boyer formally entered the capital city, Santo Domingo, where he was received by Núñez who offered to him the keys of the Palace. Boyer rejected the offer, while saying: "I have not come into this city as a conqueror but by the will of its inhabitants". The island was thus united from "Cape Tiburon to Cape Samana in possession of one government."
Eventually, the Haitian government became extremely unpopular throughout the country. The Dominican population grew increasingly impatient with Haiti's poor management and perceived incompetence, and the heavy taxation that was imposed on their side. The country was hit with a severe economic crisis after having been forced to pay a huge indemnity to France. A debt was accrued by Haiti in order to pay for their own independence from the European nation; this would give rise to many anti-Haitian plots.
Resistance

In 1838, Juan Pablo Duarte, an educated nationalist, founded a resistance movement called La Trinitaria ("The Trinity") along with Ramón Matías Mella and Francisco del Rosario Sánchez. It was so named because its original nine members had organized themselves into cells of three. The cells went on to recruit as separate organizations, maintaining strict secrecy, with little or no direct contact among themselves, in order to minimize the possibility of detection by the Haitian authorities. Many recruits quickly came to the group, but it was discovered and forced to change its name to La Filantrópica ("The Philanthropic"). The Trinitarios won the loyalty of two Dominican-manned Haitian regiments.

In 1843, the revolution made a breakthrough: they worked with a liberal Haitian party that overthrew President Jean-Pierre Boyer. However, the Trinitarios<nowiki>'</nowiki> work in the overthrow gained the attention of Boyer's replacement, Charles Rivière-Hérard. Rivière-Hérard imprisoned some Trinitarios and forced Duarte to leave the island. While gone, Duarte searched for support in Colombia and Venezuela, but was unsuccessful. Upon returning to Haiti, Hérard, a mulatto, faced a rebellion by blacks in Port-au-Prince. The two regiments of Dominicans were among those used by Hérard to suppress the uprising.
In December 1843, the rebels told Duarte to return since they had to act quickly because they were afraid the Haitians had learned of their insurrection plans. When Duarte had not returned by February, because of illness, the rebels decided to take action anyway with the leadership of Francisco del Rosario Sánchez, Ramón Matías Mella, and Pedro Santana, a wealthy cattle-rancher from El Seibo who commanded a private army of peons who worked on his estates.
On February 27, 1844, some 100 Dominicans seized the fortress of Puerta del Conde in the city of Santo Domingo, and the following day the Haitian garrison surrendered. As these Haitian troops withdrew to the west side of the island, they pillaged and burned. In retaliation, Dominican gunboats bombarded Haitian ports.
Mella headed the provisional governing junta of the new Dominican Republic. On March 14, Duarte finally returned after recovering from his illness and was greeted in celebration. The population of the new republic stood at approximately 5,200 whites, 135,000 mulattoes, and 34,000 blacks.
War of Independence
1844: First campaign
On March 7, 1844, Haiti's President Hérard ordered a blockade of Dominican ports. Three columns of Haitian troops, totaling 30,000 men, were dispatched on the 10th: one toward Las Caobas under Hérard's command, another towards Neiba, and a third to Santiago and Puerto Plata. General Santana led his cowboys westward. Skirmishes followed, with Haitian forces winning most but suffering higher casualties. The Dominicans fought with stones, knives, machetes, lances, clubs, and rifles.

After Santana's victory at the Battle of Azua on March 19, he retreated, allowing Hérard's forces to occupy Azua. The Dominicans shifted their military operations to the Ocoa River and the valleys of Baní, where their cavalry and lancers could effectively operate. This hindered the Haitian advance beyond Azua. The Haitians sustained casualties in their attempts to advance through mountain passes and were repelled. The invaders captured two towns on the Plateau du Centre and established a bastion at Cachimán. Haitian President Jean-Louis Pierrot quickly mobilized his army and counterattacked on July 13, resulting in over 200 casualties on the Haitian side, while the Dominican forces were able to repulse the attack without suffering any casualties. || 300+ dead or wounded<br>Another estimate: 1,000+ dead
