Mutiny was only prevented by the discovery of gold in the mountains near by and the arrival of reinforcements from Lima. After that he was enabled to found the town of Coquimbo on the coast about two hundred and fifty miles north of the capital, and visit Peru to arrange for the sending of more colonists and supplies. While there he assisted in the suppression of Gonzalo Pizarro’s revolt, and had no difficulty in inducing a large body of adventurers to go back with him, for Lima now was swarmed with men who were eager enough to win lands and slaves or take their chance of making their fortunes in the mines. “With their help,” says Dawson, “the conquest and settlement of all Chile as far south as the Maule was effectually completed. The land was apportioned among the cavaliers, each becoming a sort of feudal baron, and in effect creating a landed aristocracy which has continued to rule the country to the present day.” In 1544, Valdivia founded Valparaiso, the seaport of the capital, and rebuilt Coquimbo, which had been taken and burned by the neighboring Indians during his absence in Peru. He then devoted several years to making good his conquest and firmly establishing the colony, and in 1550 turned his attention to the country south of the Maule. Between the Maule and the Bio-bio were the Promaucians and their kindred tribes, and south of the Bio-bio was a confederacy composed of tribes, also related by blood and language, which inhabited the forests and mountains and lake region for a stretch of two hundred miles. Chief among these were the Araucanians—the one unconquered aboriginal race in the new world, the one aboriginal race in America, North or South, that never was conquered by Europeans, the one race that checked the victorious march of the Spaniards and compelled them, after more than a hundred years of almost incessant warfare, to acknowledge their independence and accept the Bio-bio as the southern boundary of the Spanish possessions—not warfare of the usual desultory, treacherous Indian sort, but warfare abounding in formal campaigns and sieges and pitched battles, in which large armies were engaged, in numbers often evenly matched.
