Answer:
Cattle ranching first became profitable in the future state of Oklahoma due to a combination of nutritious grass and the Indian system of communal land ownership.
Step-by-step explanation:
Before becoming the state of Oklahoma, the area belonged to Indian Territory as the five tribes (Cherokee, Chickasaw, Choctaw, Seminole and Creek) were moved west (1830). Cattle ranching started to rise thanks to the rich grass of this region, which made it possible for cattle to grow strong and healthy. Also, these tribes had a system of communal land ownership, which meant that all the region belonged to all five of them, there was no division of land or property. This allowed the cattle to move freely and a more open grazing was possibe.
