Pedro León Maximiano María Subercaseaux Errázuriz was a Chilean painter, son of the painter and diplomat Ramón Subercaseaux Vicuña. He painted many portraits about events from the history of Chile, such as the Crossing of the Andes. He painted portraits of the history of Argentina requested during the Argentina Centennial. He married Elvira Lyon Otaégui in 1907, but the Pope later annulled their marriage so that they could both get into religious orders.

Lautaro was a young Mapuche toqui known for leading the indigenous resistance against Spanish conquest in Chile and developing the tactics that would continue to be employed by the Mapuche during the long-running Arauco War. Levtaru was captured by Spanish forces in his early youth, and he spent his teenage years as a personal servant of chief conquistador Pedro de Valdivia, but escaped in 1551. Back among his people he was declared toqui and led Mapuche warriors into a series of victories against the Spanish, culminating in the Battle of Tucapel in December 1553, where Pedro of Valdivia was killed. The outbreak of a typhus plague, a drought and a famine prevented the Mapuche from taking further actions to expel the Spanish in 1554 and 1555. Between 1556 and 1557, a small group of Mapuche commanded by Levtaru attempted to reach Santiago to liberate the whole of Central Chile from Spanish rule. Levtaru's attempts ended in 1557 when he was killed in an ambush by the Spanish.
