How did Joseph Glidden and John Deere impact settlement in the west?

Joseph Glidden and JOHN DEERe significantly influenced westward settlement by providing essential tools for agriculture. Glidden invented barbed wire in 1874, which facilitated the Fencing of land, enabling settlers to efficiently manage livestock and protect crops. Meanwhile, John Deere's development of the steel plow in 1837 made it easier to cultivate the tough, prairie soil, promoting farming in previously challenging areas. Together, their innovations helped transform the Great Plains into productive farmland, encouraging more settlers to move westward.
