Oklahoma Counties

There are seventy-seven counties in Oklahoma. Oklahoma originally had seven counties when it was first organized as the Oklahoma Territory. These counties were designated numerically, first through seventh. New counties added after this were designated by letters of the alphabet. The first seven counties were later renamed. The Oklahoma Constitutional Convention named all of the counties that were formed when Oklahoma entered statehood in 1907. Only two counties have been formed since then

Tulsa County History

In 1910, Tulsa County built a court house in Tulsa on the northeast corner of Sixth Street and South Boulder Avenue. Yule marble was used in its construction. The land had previously been the site of a mansion owned by George Perryman and his wife. This was the court house where a mob of white residents gathered on May 31, 1921, threatening to lynch a young black man held in the top-floor jail. It was the beginning of the Tulsa Race Riot.

An advertisement for bids specified that the building should be fireproof, built of either reinforced concrete or steel and concrete. The size was to be 120 feet (37 m) by 120 feet (37 m) with three floors and a full basement. Cost of the building was not to exceed $200,000. The jail on the top floor was not to exceed $25,000.

The building continued to serve until the present court house building (shown above) opened at 515 South Denver. The old building was then demolished and the land was then sold to private investors. The land is now the site of the Bank of America building, completed in 1967.

Oklahoma History Center
Located in eastern Oklahoma, Tulsa County took its name from the already established town of Tulsa. Areas of the old Creek and Cherokee nations comprise the county. It is bordered on the north by Osage, Washington, and Rogers counties, on the east by Rogers and Wagoner, on the south by Okmulgee, and on the west by Creek and Osage counties. Tulsa, the state's second largest populated city, serves as the county seat. Other incorporated towns are Bixby, Broken Arrow, Collinsville, Glenpool, Jenks, Owasso, Sand Springs, and Sperry.

The Arkansas River drains most of the county, but tributaries of the Verdigris, principally Bird Creek and the Caney River, drain the northern portion. Tulsa County contains 587.02 miles of land and water area. The landscape embodies prairies and sandstone hills, with the lowlands of the Arkansas River Valley providing excellent farming soil. In 1965 the US Army Corps of Engineers completed Keystone Dam on the Arkansas River in Tulsa County, creating Keystone Lake. Most of the lake lies in Osage, Pawnee, and Creek counties....TULSA COUNTY
