Final answer:
The rapid influx of settlers to California in the late 1840s and early 1850s was primarily caused by the Gold Rush.
Step-by-step explanation:
In the late 1840s and early 1850s, California experienced a rapid influx of settlers due to the Gold Rush. Gold was discovered in California in 1848, attracting people from all over the world in search of wealth and opportunities. The news of the gold discovery spread rapidly, leading to a massive migration to California.
The promise of wealth and success drew people from various backgrounds, including miners, merchants, farmers, and professionals. This influx of settlers greatly accelerated the population growth in California during that time.
This event had significant social, economic, and political consequences, shaping the future development of California as a state.
