Final answer:
The Oklahoma land rush occurred in the 1890s and involved the first-come distribution of lands in Oklahoma, not directly tied to the discovery of a mineral but to the availability of land for settlement.
Step-by-step explanation:
The Oklahoma land rush was a series of events that took place in the 1890s where land was distributed on a first-come basis to settlers in what is now the state of Oklahoma. This movement was not due to the discovery of any particular mineral but was rather the result of the federal government opening up previously Native American lands for non-Indian settlement. While the discovery of minerals like gold and silver spurred other rushes in Western territories, such as the California Gold Rush and the Comstock Lode, the Oklahoma land rushes were primarily driven by the availability of land for agriculture and settlement.
