Black and Tan Republicans

Black and Tan Republicans were African Americans in the Reconstruction-era South who were loyal to the Republican Party.  When the Republican Party was founded in 1854, few African Americans joined.  By the time of the election of Abraham Lincoln, the Party began to attract support from Northern blacks. That support continued to grow into the late 1860's as many Southern blacks, now voting, cast ballots for the Republicans.

After the 15th Amendment to the US Constitution was passed in 1870, allowing most of the black males in the former Confederate states to vote,  the Republican Party (also known as the Grand Old Party or GOP) commanded the loyalty of an overwhelming majority of African Americans. Many of the newly enfranchised Southern black men now formed "Black and Tan" clubs, which along with similar organizations like the Union League, helped to institutionally tie these voters to the Republican Party. 

Black Republican votes were also driven by white terror.  Beginning with the founding of the Ku Klux Klan in 1866 and escalating through the late 1860s and 1870s, Southern whites used violence to intimidate black would-be voters which at first helped solidify their allegiance to the GOP.  Thousands of black voters were murdered in Texas, Louisiana, Mississippi, and South Carolina.  White terrorists also intimidated and ostracized Southern whites who supported the Republican Party.  They harassed the children of white Republicans in schools and isolated the wives of prominent white Republicans in churches and social clubs.  On many occasions direct violence, usually reserved for African American Republican voters, was used on white Party activists as well. 

The violence and intimidation of black and white voters, destroyed the effectiveness of the Republican Party in most areas of the South as an alternative to one-party (Democratic) rule.  Whites left the GOP and rejoined the Democrats or quit politics altogether.  Blacks who continued to vote did so at the risk of being killed.    

White Republicans who remained in the Party were increasingly convinced that they could survive politically only by removing black GOP officeholders and leaders and in some instances by jettisoning black voters completely.  These Republicans, fought the Black and Tan Republicans for control of the Party.  They remained warring factions until the 1930s when African Americans deserted the GOP to support the policies and administration of Democratic President Franklin D. Roosevelt.

As a side note, it was the signing of Civil Rights Legislation by President Lyndon Johnson in 1964 when White and Black Southerners left the Democrat party and returned to the Republican Party that we know today.
