What new invention created conflict between the homesteaders and the cowboys because it made it hard for them to complete their cattle drives?

The invention of barbed wire created significant conflict between homesteaders and cowboys, as it was used to enclose vast tracts of land, disrupting traditional cattle drives. Cowboys relied on open ranges for grazing and moving cattle, but the proliferation of fenced land made it difficult to navigate and access grazing areas. This led to tensions as homesteaders sought to protect their crops and property, while cowboys struggled to maintain their livelihoods. The shift in land use contributed to the broader challenges of adapting to a changing landscape in the American West.
