How did the Homestead Act create conflicts between settlers and native americans?

Hint: The Homestead Act, enacted in 1862 during the Civil War, provided that 160 acres of surveyed government land could be claimed by any adult citizen, or intended citizen, who had never carried arms against the United States government.
By building a dwelling and cultivating the land, claimants were required to "improve" the plot. The original filer was entitled to the property after 5 years on the land, free and clear, except for a small registration fee.

Complete answer:
Congress passed the Homestead Act when the national government wanted to promote the settlement of the western territories. The act will grant a family 100 acres of land, given they have been farming on the land for at least 5 years. Since many Native Americans had already been forced out of their lands from the eastern part of America at this time, they had migrated to these western territories.

Since land was practically free, there were certainly more individuals willing to take up the offer and go out and settle some land. 100 acres is a decent size in itself, and since people mostly settled the midwest/great plains at that time, There were more disputes since the Native Americans mostly relied on hunting Buffaloes in this region and many were nomadic.

In combination with travelling Native Americans, the amount of land settled by individuals certainly caused conflicts between Native Americans and settlers to be established.

Note: The Civil War-era Act, considered one of the most significant pieces of legislation in the United States, contributed to Western expansion and enabled landowners to become citizens of all walks of life, including former slaves, women and immigrants.
However, the act turned out to be no panacea for poverty. Similarly, few workers and farmers could afford to develop a farm or obtain the requisite equipment, seeds, and livestock
