Oklahoma is home to the largest ancient meteorite impact site in the United States. The impact crater, which is located in northeastern Oklahoma, is estimated to be about 300 million years old.
Okmulgee County is located in eastern Oklahoma and holds a rich history. The area was originally inhabited by Native American tribes, including the Creek Nation, who were forced to relocate to Indian Territory in the 1830s. The Creek Nation established their capital at Okmulgee, which eventually became the county seat.

In the late 19th century, the discovery of oil brought significant changes to Okmulgee County. Oil fields were developed, attracting investors and workers to the region. The oil boom led to the rapid growth of Okmulgee and the surrounding areas, bringing wealth and prosperity. The city became known as the "Oil Capital of the World," with a thriving industry that created jobs and boosted the local economy.

During this era, Okmulgee County was also home to a vibrant African American community. Greenwood, a neighborhood in the city of Tulsa, just north of Okmulgee County, became an economic and cultural hub for Black residents. However, in 1921, the notorious Tulsa Race Massacre occurred, resulting in the destruction of Greenwood and significant loss of life. The impact of the massacre was felt in Okmulgee County as well, as many residents from Greenwood sought refuge in nearby communities.

In the years following the oil boom, Okmulgee County faced economic decline as oil production declined and industries shifted. However, the county has made efforts to diversify its economy, focusing on agriculture, manufacturing, and tourism. Today, Okmulgee County is known for its beautiful natural landscapes, historic downtown, and cultural heritage. The Muscogee (Creek) Nation is still an influential presence in the area, with a strong connection to its Native American heritage.
