In 1861, after imprisoning, silencing, exiling, and executing many of his opponents and due to political and economic reasons, Santana signed a pact with the Spanish Crown and reverted the Dominican nation to colonial status. This action was supported by the cattlemen of the south while the northern elites opposed it. Spanish rule finally came to an end with the War of Restoration in 1865, after four years of conflict between Dominican nationalists and Spanish sympathizers. The war claimed more than 50,000 lives.
