History
This was the Mapuche heartland. Spanish conquistadors founded Valdivia in 1552 and a string of towns south of the Biobío, but a great uprising after the battle of Curalaba in 1598 destroyed them, and for more than two centuries the Mapuche held the land between the Biobío and the Toltén, negotiating with the Spanish crown at formal parliaments. Valdivia was refounded in 1645 as a fortified outpost, guarded by forts at Corral, Niebla and Mancera, and Chiloé remained a Spanish stronghold until 1826, the last part of Chile to fall to the republic.
In the mid-19th century the Chilean state moved south. From the 1840s it recruited German settlers, who cleared forest around Valdivia, Osorno and Lake Llanquihue and founded Puerto Montt in 1853. Between 1861 and 1883 the army occupied the Araucanía in the campaign known in Chile as the Pacification of the Araucanía; Mapuche communities were confined to reserves, and Temuco, founded as a fort in 1881, grew into the regional capital.
On 22 May 1960 the Valdivia earthquake, the most powerful ever recorded, struck the region, followed by a tsunami that swept the coast and Chiloé. The land question has never been settled: Mapuche organisations continue to claim ancestral territory, while the state, farmers and forestry companies defend their titles. Los Ríos became a separate region in 2007.
