There was more information written on the Antuco area (a few dozen kilometers to the north) where there was a strong commercial activity between Creoles and Pehuenches.

This is reflected in the travel books of the Polish naturalist Ignacio Domeyko and the Bavarian artist Mauricio Rugendas, who made the first portraits of the indigenous people.

The tranquility of the area was interrupted in the 19th century by the hunts of the Chilean armies of the montoneros still faithful to the Spanish Kingdom or of the bands of rustlers that ravaged the haciendas of the Creoles in the plain (Los Pincheira brothers wrote some of their chapters in Alto Bio Bío).

[1] Within the electoral divisions of Chile, Alto Bío Bío is represented in the Chamber of Deputies by Juan Lobos (UDI) and José Pérez (PRSD) as part of the 47th electoral district, together with Los Ángeles, Tucapel, Antuco, Quilleco, Santa Bárbara, Quilaco, Mulchén, Negrete, Nacimiento, San Rosendo and Laja.

The commune is represented in the Senate by Victor Pérez Varela (UDI) and Mariano Ruiz-Esquide Jara (PDC) as part of the 13th senatorial constituency (Bío Bío-Coast).

The commune has impressive natural attractions characterized by the native flora and fauna of the Andes Mountains and the presence of two active volcanoes (Callaqui and Copahue).
