Answer: The first American migrants faced an undeveloped territory, with a hot climate, and a hostile terrain for agriculture, they also faced crime and little government control of the territory.
Step-by-step explanation:
The territory of California before the annexation to America was populated only by religious missions with few inhabitants. After the Guadalupe-Hidalgo treaty, the territory was annexed as a state of the United States of America in 1848.
After the annexation, gold was discovered in the state, this led to the well-known "gold rush", and attracted thousands of people to the state. These immigrants faced an undeveloped and hostile terrain, the climate was hotter than they were used to and it was more difficult to cultivate.
They also faced high rates of crime, and little government control because the gold rush attracted all kinds of people in a short amount of time.
