## History

At the time of Spanish contact, the area of what is now Genaro Codina was populated by the Zacateco people. In 1542, the settlement of San José de la Ysla (or Isla) was founded. Tlaxcalan colonists joined the settlement in 1591.

Its municipal government (junta municipal) was first established on 29 October 1833. It dropped the "San" from its name in 1935, becoming known as José de la Isla.

A health centre was inaugurated in Genaro Codina in 1964, and electricity and water services followed in 1971.
