Overview

The 12th Oklahoma Legislature was the state legislative body that convened in Oklahoma City during 1929. Like other Oklahoma legislatures, it consisted of two chambers: the Oklahoma Senate and the Oklahoma House of Representatives. Its regular session ran from January 8 through March 30, 1929, followed by a special session called by Governor William J. Holloway that met from May 16 until July 5, 1929. The legislature is chiefly remembered for its confrontation with Governor Henry S. Johnston. During the regular session, members of the Oklahoma House of Representatives brought thirteen charges against Johnston. On January 21, 1929, the legislature suspended him from office, allowing Lieutenant Governor William J. Holloway to serve as acting governor. Johnston's impeachment trial began in February and concluded in March. He was convicted and removed on one charge, after which Holloway succeeded him as Oklahoma's eighth governor. The proceedings represented one of the most consequential uses of the legislature's constitutional oversight powers in the state's early history. The legislature also experienced a change in Senate membership at the beginning of its term. Harry D. Henry died on January 8, 1929, leaving the Fourth Senate District vacant. W. M. Williams was elected to fill that vacancy on January 29. The body's recorded leadership included C. S. Storms as president pro tempore of the Senate and James C. Nance as speaker of the House of Representatives. Following the regular session, Governor Holloway convened a special session on May 16. The special session remained in session until July 5 and addressed, among other matters, the proposed acquisition of toll bridges along Oklahoma's borders. The 12th Legislature therefore combined routine lawmaking and appropriations-related state administration with a high-profile constitutional conflict over executive conduct. It was succeeded by the 13th Oklahoma Legislature. As a historical legislative term rather than a continuing organization or commercial brand, it has no independent corporate ownership, product portfolio, commercial headquarters, or public-market listing.

History

The 12th Oklahoma Legislature was the twelfth convening of Oklahoma's state legislature. It met in Oklahoma City and was composed of the Oklahoma Senate and the Oklahoma House of Representatives. The regular session began on January 8, 1929, and ended on March 30. The session became historically significant because of its action against Governor Henry S. Johnston. House members submitted thirteen charges against him, and on January 21 the legislature suspended him from office. Lieutenant Governor William J. Holloway consequently assumed the role of acting governor. Johnston's impeachment trial opened in February and ended in March. The legislature impeached him on one charge, leading to his removal and Holloway's succession as the eighth governor of Oklahoma. The legislature also underwent a membership change in the Senate. Harry D. Henry died on the first day of the session, creating a vacancy in Senate District 4. W. M. Williams was elected to that seat on January 29. After the regular session, Holloway called the legislature back for a special session on May 16. That session continued until July 5 and included consideration of acquiring toll bridges located along Oklahoma's borders. The 12th Legislature was then followed by the 13th Oklahoma Legislature. Its historical significance rests primarily on the impeachment and removal of a sitting governor, together with the institutional response to executive succession and the infrastructure questions addressed during the special session.
