In 1670 Jesuit father Nicolás Mascardi, based in Chiloé Archipelago, entered the area through the Reloncaví Estuary and Todos los Santos Lake to found a mission at the Nahuel Huapi Lake, which lasted until 1673. A new mission at the shores of Nahuel Huapi Lake was established in 1703, backed financially from Potosí, thanks to orders from the viceroy of Peru. Historians disagree if the mission belonged to the jurisdiction of Valdivia or Chiloé. According to historic documents, the Poya of Nahuelhuapi requested the mission to be reestablished, apparently to forge an alliance with the Spaniards against the Puelche. Following the 1712 Huilliche rebellion in Chiloé Archipelago some insurgents sought refuge with Father Manuel del Hoyo in the mission.
