Final answer:
The desire for men to migrate west in 1849 was primarily driven by the California Gold Rush, the promise of free land through the Homestead Act of 1862, and the completion of the transcontinental railroad in 1869.
Step-by-step explanation:
The desire for men to migrate west in 1849 was primarily driven by the California Gold Rush. When gold was discovered in California, thousands of people from all over the world flocked to the region in search of wealth and economic opportunities. This massive influx of people fueled the desire for men to migrate westward.
Another factor that contributed to this desire was the promise of free land through the Homestead Act of 1862. This act allowed individuals to claim up to 160 acres of land in the western territories, incentivizing migration.
Lastly, the completion of the transcontinental railroad in 1869 made it easier and faster for people to travel west. This transportation infrastructure opened up new possibilities for trade and settlement, further fueling the desire to migrate west.
