Although there are petroglyphs and traces of Ta�no people in Adjuntas, there is no proof that the region was dominated by a specific cacique. Nearby caciques like Guarionex and Urayo�n could've had some control over the area.
According to historian Aurelio Ti�, during the Spanish colonization of Puerto Rico in the 16th Century, it is believed that a Spanish interpreter called Juan Gonz�lez settled in the region. Also, historian Cayetano Coll y Toste wrote a leyend about Spanish people looking for gold in the region of Adjuntas.

With 20 families established in the region, the residents of Adjuntas vouched for the settlement to be officially recognized. The town of Adjuntas was then founded in August 11, 1815, with Diego Maldonado being elected as its representative. A city hall and public square were built shortly after.
Adjuntas was one of the main cities where the Anusim, Maranos, and other Sephardi Jews settled. Many of these families were of the Torres, Perez or Peretz, and Bennazzar families among others. Berberena and Mozarabes settled there too.
Ta�no families from neighboring Utuado can also be found in this area, along with escaped cimarrones, or African slaves, who intermarried with the Ta�no. DNA genetic evidence shows that many Africans fled up the Camino Real into the mountains to escape the sugar plantations of Ponce. The Mandinka, Wolof & Fulani mtDNA African haplo type, L1b, is present here. Ta�no haplo groups A & C can also be found in this area.
