Final answer:
Barbed wire, known as the "devil's rope," revolutionized land demarcation in the American West after its invention by Joseph Glidden in 1873, leading to the end of communal grazing and affecting Native tribes.
Step-by-step explanation:
Barbed wire, often referred to as the "devil's rope" by Native Americans, brought significant changes to the American West.
The minimum requirements for standard barbed wire typically include specifications on the gauge of wire, the type of metal used, the spacing of barbs, and the overall tensile strength, to ensure its effectiveness in fencing. The invention of barbed wire by Joseph Glidden in 1873 marked a pivotal moment in history. It enabled settlers and ranchers to demarcate their lands affordably and efficiently, which previously was not possible due to a lack of fencing materials. This led to the privatization of open communal grazing lands, the decline of long cattle drives, and restricted access to land for Native tribes.
