The Green Party of Oklahoma is a political party in the U.S. state of Oklahoma. It was formed in 2002 through a gradual coalition of various state green groups and received its accreditation from the Green Party of the United States (GPUS) in May 2005. Its stated aims are a commitment to environmentalism, non-violence, social justice, and grassroots democracy. The party has been active in organizing around issues of peace, the death penalty, minority language rights, gay rights, rural sustainability, and academic freedom. The party has also worked with the Oklahoma Libertarian Party and the Oklahoma Constitution Party in seeking to reform Oklahoma's restrictive ballot access laws. In 2000, the party gathered nomination signatures to place Ralph Nader on the Oklahoma Presidential ballot but was unable to collect a sufficient amount. In 2016, the Green Party of Oklahoma broke with the GPUS when it endorsed Senator Bernie Sanders in the Oklahoma's Democratic presidential primary. History 1990s The state party's original roots are not certain, but the best known history is that there were two local Green Party chapters active in the late 1990s, the Central Oklahoma Green Party (which later split into the Oklahoma County Green Party and the Cleveland County Green Party) and the Green Country Green Party (representing the Tulsa metropolitan area and Northeastern Oklahoma). Prior to the formation of a statewide party, Green Party members in Oklahoma (through statewide nominating conventions) sent delegates to the national Green Party nominating conventions in 1996. Greens statewide also cooperated in the publication of The Greenleaf (a state Green Party newspaper). 2000s Oklahoma Greens sent delegates to the national Green Party nominating convention in 2000 (through a statewide nominating convention, since there was not yet an organized state Green Party organization). Oklahoma Greens unsuccessfully petitioned to place Ralph Nader on the Oklahoma Presidential ballot and after failed litigation by the national Green Party, Oklahoma Greens protested his exclusion from the state's Presidential ballot. In 2002, the local chapters joined together in issuing a call for the Founding convention of the Green Party of Oklahoma, which was held at the Cleveland County Fairgrounds in Norman on November 16, 2002. At this convention the party elected the following members to the state executive board: Rachel Jackson & Ben Alpers as co-chairs, Danelle as Secretary, Doug Vincent as Treasurer, and James M. Branum, Alice Anderton, and Brian Wright as members at large. (shortly after
