Short answer: Spanish forces captured the Inca ruler Atahualpa at Cajamarca in November 1532. He offered an enormous ransom. Gold and silver objects were brought to the city, where they were melted and distributed. Atahualpa was executed in 1533 despite the payment. No reliable historical record proves that another ransom caravan was hidden in Ecuador’s Llanganates Mountains.
What happened at Cajamarca?
Francisco Pizarro’s much smaller force seized Atahualpa during a violent encounter in the plaza at Cajamarca. While imprisoned, Atahualpa offered to fill a room with gold to the height he could reach. He also promised further silver. The building known as the Ransom Room remains associated with that episode.
Was the ransom lost?
The treasure that reached Cajamarca was not lost. Spanish records describe it being counted before it was melted and divided. Referring to the whole ransom as lost hides that important part of the story.
Where does the Llanganates legend begin?
A later tradition says that the general Rumiñahui was carrying more treasure when he heard of Atahualpa’s death. According to the story, he concealed the gold in remote country, often identified with the Llanganates. Over time, supposed maps and routes became part of the legend. None has led to a find accepted as Atahualpa’s missing ransom.
Evidence boundary: Atahualpa’s capture and ransom are historical events. A surviving royal cache in the Llanganates is an unverified legend.
