The Araucanians inhabit the southern part of Chili, and derive their name from the province of Arauco. They are a nation enthusiastically attached to freedom, and pride themselves in the appellation of Auca, which signifies free. They are muscular, robust, of great strength of constitution, and often attain the age of 90 or 100 years. They are bold and warlike, and have ever been most determined foes to all the Spanish invaders of their native country; and, by their warlike disposition and fiery courage, have occasioned great trouble to the Spaniards ever since they became acquainted with them. All attempts to subjugate them to the sway of the Europeans have been unsuccessful.

Their military system is greatly superior to that of the surrounding nations, and the degree of discipline they had gained enabled them to carry on long and bloody wars with the Spaniards who overrun Chili, in the early part of the sixteenth century. Their state was divided into four nearly equal portions, to which they gave the name of the maritime country, the plain country, the country at the foot of the Andes, and that of the Andes. Each of these great divisions was also subdivided into five smaller ones, and each of these in turn into nine still less. These divisions of Araucania were existing previous to the arrival of the Spaniards.

The government, which is aristocratic, is said to be a sort of state, in which there are three orders of nobility, with gradations of rank, called the toquis, the asse-ulmenes, and the ulmenes, all of whom have their vassals. Each order has its badge, and the triple power that constitutes the sovereign authority is vested in a general diet, or grand council, which is usually held in some large plain, where they feast and deliberate. The grand council elect a commander-in-chief to lead them in war, who may belong to the inferior ranks, if he is thought of greater ability than any one in the superior ranks. The Puelches, a hardy race of mountaineers, formerly a distinct people, have been united with the Araucanians, under the same government, and this part of the nation are considered entitled to have the vice-toqui chosen from among them.

The first account we have, which may properly be called the history of this people, is at the beginning of their wars with the Spaniards, in 1550. Their toqui was named Aillavila, and the Europeans having invaded the inhabitants of Penco, the Araucanians ordered that officer to march to their assistance at the head of 4,000 men. He accordingly crossed the great River Biobio, the northern boundary of Araucania, and boldly offered battle to the Spaniards. Unlike the other Indians, with whom the Spaniards had been engaged, the Araucanians were not disconcerted or terrified by the discharge of fire-arms, but fell at once on the front and flanks of the enemy who were thrown into confusion. Valdivia, their general, had his horse killed under him, and was exposed to great danger, when the toqui received a mortal wound, in consequence of which the Indians drew off in good order and unpursued by the Europeans. Valdivia, who had been in many battles both in Europe and America, declared that his life had never been in such great hazard in any of them as in this engagement.

The next year, the Araucanians were again led on by their new toqui, Lincoyan, and the Spaniards, remembering the former engagement, were inspired with such terror, that after confessing themselves, and receiving the sacrament, they took shelter under the cannon of their fortifications. In his first attack on these, Lincoyan was unsuccessful, and obliged to retreat, which the Spaniards ascribed to the immediate interposition of St. James, their patron saint, who they affirmed was seen riding on a white horse, armed with a flaming sword, and striking terror into their enemies. The governor having received some reinforcements from Peru, after a year elapsed, resolved to attack them; and, unopposed by Lincoyan, he penetrated to the Cauten, by which Araucania is divided into two equal parts. Here he built a city which he called Imperial, and also despatched one of his officers to found another, called Villarica, on the Lauquen.

Proceeding on, he traversed the whole of Araucania, from north to south, with but small loss, and finally arrived at the territory of the Cunches. Here he found a valiant nation, allies of the Araucanians, who were prepared to oppose his passage of the Calacalla. The Cunchese general, however, was induced to permit the invaders to pass unmolested. Valdivia here founded another city, to which he gave his own name, and then, satisfied with his conquests, prepared to return, building fortresses and founding cities in various parts. Ercilla says that the Spaniards in this expedition had to fight many battles, but the details are not given.

To Lincoyan, succeeded Caupolican, an account of whose exploits has been already given in another volume of this Library. He was a brave warrior, and drove the Spaniards from several of the towns and fortresses which Valdivia had established. But these successes were succeeded by a severe reverse, and he was on the point of being defeated, when Lautaro, incited by patriotism, broke forth from the Spanish ranks, and led on his countrymen to victory. The whole Spanish army was destroyed except a few prisoners, and two Promaucians, their Indian allies.

After the death of Valdivia, who was put to death while pleading for his life, the Spaniards evacuated all the cities which the Spanish governor had founded, except two. These were immediately besieged by Caupolican, while Lautaro, now appointed lieutenant-general, or vice-toqui, fortified himself for the defence of the frontiers on the lofty mountains of Mariguena. The mountain being full of precipices and clefts, and covered on one side by impenetrable thickets, presented only a single winding by-path, which led to the top of the mountain. Villagran, the successor of Valdivia, engaged in battle with the young Lautaro, but, after a desperate fight, he was worsted, and compelled to retire. Believing it impossible to defend the city of Concepcion, he embarked a portion of the inhabitants, consisting of old men, women, and children, on board of two ships, then in the harbour, while he led the remainder to Santiago.

Lautaro entered the deserted city, where he found a great booty, and after having plundered it, burned the houses, and razed the citadel to the ground, and returned in triumph to Arauco. Caupolican, however, was forced to raise the siege of Imperial and Valdivia, in consequence of the strong reinforcements which had been thrown into them by Villagran. While he was engaged in ravaging the country around Imperial, the small-pox, that destructive scourge of the natives, made its appearance, probably communicated by some Spanish soldiers, and made terrible havoc, so that there were some districts almost depopulated. In one of these containing 12,000 inhabitants, it is asserted that not more than 100 persons escaped death.
