In 1791, the group from the Franciscan Theological Order led by Manuel Sobreviela created Tocachi while they were searching El Dorado (with the Cholones Indians). The town was abandoned after the independence of Peru and in 1914 the settlers founded Juan de Tocache. It was located in the confluence of the rivers Huallaga and Tocache. The settlers extracted rabber to export to Europe but after the 1st World War this industry ends. In 1936 they decided to move the town because it suffered inundations, they relocated it in the Pato ravine (now Rio de la Plata) and they named it Pato or Puerto Pato, but after 4 years it took the name of Tocache Nuevo. After some years, it was designated with the district’s category and it became part of the province of Mariscal Caceres.
