By the time of the Dominican War of Independence, Jimani was practically deserted with most of the fighting taking place in Neiba. After the independence of 1844 the earliest inhabitants of Jimaní came from various communities of the southwest, such as Neiba, Duvergé, El Estero, Las Salinas, Azua de Compostela, Santa Cruz de Barahona, and Haitian immigrants from the mountains that married or had common-law marriages with Dominicans, forming families in the most populous neighborhood of the community, known as Jimaní Viejo. By the 1930s Jimaní belonged to Neiba and in 1938 it became part of the commune of La Descubierta, forming a part of the Province of Baoruco.
