Historical Trajectory
Phase I: Rise
On February 27, 1844, a group of patriots led by Juan Pablo Duarte and allied Dominican leaders proclaimed independence from Haiti, ending over two decades of Haitian occupation of Santo Domingo. The new republic swiftly promulgated its first Constitution in November 1844, establishing a republican and democratic system, though it immediately faced military pressure from Haiti and competing external interests from Spain, France, Britain, and the United States.
Phase II: Zenith
Despite chronic instability, the First Republic maintained sovereign institutions and a constitutional order for seventeen years. The period saw the construction of foundational state structures, the organization of a national army, and repeated successful defenses against Haitian invasions. Pedro Santana and Buenaventura Báez alternated in power, each consolidating control while nominally preserving republican forms and seeking foreign alliances to guarantee national security.
Phase III: Decline
Political infighting between conservative caudillos and liberals, combined with ongoing Haitian military threats and economic weakness, eroded the republic's stability. Pedro Santana, seeking external protection, negotiated the voluntary annexation of the Dominican Republic to Spain. On March 18, 1861, the country was formally reincorporated into the Spanish Crown, bringing the First Republic to an end and precipitating the subsequent War of Restoration.
