A lonko or lonco (from
Mapudungunlongko, literally "head"), is a chief of several[citation needed]Mapuche communities. These were often
ulmen, the wealthier men in the
lof.[1] In wartime, lonkos of the various local
rehue or the larger
aillarehue would gather in a
koyag or parliament and would elect a
toqui to lead the warriors in battle.[2]Lonco sometimes forms part of geographical names such as the city of
Loncoche (English: "head of an important person").
