Samuel Green (November 18, 1889 – August 18, 1949) was a Grand Wizard of the Knights of the Ku Klux Klan in the late 1940s, organizing its third and final reformation in 1946.

In 1939, Imperial Wizard Hiram Wesley Evans sold the organisation to two Klan members, Green and James A.

[3] While Colescott was forced to dissolve the organization in 1944, Green began to reform the Association of Georgia Klans with its focus on white supremacy and anti-communism.

[2] From the autumn of 1945 to the spring of 1946, the Klan regularly signaled their presence through lighting up "huge fiery crosses" on top of Stone Mountain.

According to historian Robert P. Ingalls, the fiery cross lit for the ceremony was between 200 and 300 feet in height (60.96-91.44 metres).

Chester L. Quarles, a professor of criminal justice at the University of Mississippi, points out that new conditions in the region helped the Klan in its recruitment drive.

[5] Another factor to the revitalization of the Klan was a then-recent wave of refugees and immigrants entering the United States, including Jews who survived the Holocaust.

The Klan was opposed to the labor movement and Green characterized these organizers as carpetbagger arriving to "tell Southerners how to run ... their business".

[5] Green assured his audience that "niggahs" (sic), Jews, Catholics, labor organizers, and any alliance between them would not be tolerated by the Klan.

The practice both asserted their predominance in their respective areas, and implied their connection to local church leaders.

For example, Hugh A. Brimm of the Southern Baptist Convention instructed its pastors to refuse to accept "blood money" from the Klan.

While declaring itself the "American social conscience", the Klan consistently favored ignoring and disobeying laws which went against their ideology.

The most notable infiltrator was Stetson Kennedy, whose later book I Rode With The Ku Klux Klan (1954) covered the activities of the Klavalier Klub.

He was active in the 1948 Georgia gubernatorial special election, reportedly serving as an aide-de-camp to candidate Herman Talmadge.

[5] He was elected Imperial Wizard two weeks before his death from a heart attack in Atlanta, Georgia on August 18, 1949.

[7] During the exhibition games, Green used the influence of Herman Talmadge to try and ban Dodgers players Jackie Robinson and Roy Campanella.
