Answer:
The Spanish population in Chile was mostly concentrated in the capital city of Santiago, founded by Pedro de Valdivia on February 12, 1541.
Step-by-step explanation:
In the north, many Amerindians were subdued into forced labor, but in the south, the Araucanians were fiercely defending their territory.
Valdivia did manage to set forts in the south, but they were under constant Araucanian attacks. Even after the Araucanian resistance was defeated, the Mapuches prevailed on to the remaining territory for a long time.
