"The inhabitants of California have no reason to complain of the change of government, for if the rich land of their birth has been taken from them, they have at least been compensated by the security of their persons and property... But, alas! The gold mines were discovered, and a torrent of immigrants poured into the country. The new arrivals did not come to till the soil or build homes, but to search for gold. They looked upon us as a conquered race, and treated us accordingly, ignoring our rights and our laws."
— Mariano Guadalupe Vallejo, *Historical and Personal Memoirs Relating to Alta California*, c. 1875
