It's a common response that, when pressed with the fact that the GOP tends to vote against minorities, that Conservatives will take time to remind us that Republicans were the party of Lincoln. And that eventually, Blacks slowly betrayed the Republican Party that helped them be free. Or, just that it was the Republicans who freed them.

In short, yes, a Republican freed the slaves. Then Republicans sold out blacks. And then when Democrats started to care about the blacks they largely didn't care for before, the Citizens and Politicians of this nation turned into Republicans to attempt to slow down any progress Blacks could make.

Compromise of 1877
The Compromise of 1877 was an informal agreement between southern Democrats and allies of the Republican Rutherford Hayes to settle the result of the 1876

During the commission’s deliberations, Hayes’ Republican allies met in secret with moderate southern Democrats in hopes of convincing them not to block the official counting of votes through filibuster and effectively allow Hayes’ election. In February, at a meeting held in Washington’s Wormley Hotel, the Democrats agreed to accept a Hayes victory, and to respect the civil and political rights of African Americans, on the condition that Republicans withdraw all federal troops from South, thus consolidating Democratic control in the region. Hayes would also have to agree to name a leading southerner to his cabinet and to support federal aid for the Texas and Pacific Railroad, a planned transcontinental line via a southern route. On March 2, the congressional commission voted 8-7 along party lines to award all the disputed electoral votes to Hayes, giving him 185 votes to Tilden’s 184.
Hayes appointed Tennessee’s David Key as postmaster general, but never followed through on the promised land grant for the Texas and Pacific. Within two months, however, Hayes had ordered federal troops from their posts guarding Louisiana and South Carolina statehouses, allowing Democrats to seize control in both those states. As Florida’s Supreme Court had earlier declared a Democratic victory in the 1876 gubernatorial election, Democrats had been restored to power all across the South.
The Compromise of 1876 effectively ended the Reconstruction era. Southern Democrats’ promises to protect civil and political rights of blacks were not kept, and the end of federal interference in southern affairs led to widespread disenfranchisement of blacks voters. From the late 1870s onward, southern legislatures passed a series of laws requiring the separation of whites from “persons of color” on public transportation, in schools, parks, restaurants, theaters and other locations. Known as the “Jim Crow laws” (after a popular minstrel act developed in the antebellum years), these segregationist statutes governed life in the South through the middle of the next century, ending only after the hard-won successes of the civil rights movement in the 1960s.

'Racially conservative' attitudes led white Southerners to leave Democratic Party
Racial attitudes were the primary reason white Southerners left the Democratic Party in the last half of the 20th century, a study finds.

It’s a widely held belief that white Southerners began to leave the Democratic Party after Democratic President Lyndon Johnson signed the 1964 Civil Rights Act, outlawing segregation in business such as restaurants and hotels and in public places such as schools and swimming pools. However, this new study finds that “racially conservative” whites in the South started switching to the Republican Party in the early 1950s in reaction to Democratic President Harry Truman’s support for civil rights initiatives in the late 1940s.
Before 1950, nearly 80 percent of white adults who lived in the 11 states of the former Confederacy identified as Democrats, compared with about 40 percent of white adults in other parts of the country, the study shows. By the early 2000s, about 30 percent of white adults in the South and nationwide identified as Democrats.
Since then, the percentage of white Southerners who consider themselves Democrats has not changed much. In 2014, 31 percent of white Southerners said they were Democrats or leaned Democratic, a Pew Research Center survey found.
Ilyana Kuziemko, an economics professor at Princeton, and Ebonya Washington, an economics professor at Yale, present new evidence to explain what they call “one of the largest and most debated partisan shifts in a modern democracy.” Despite decades of study, scholars have yet to reach a consensus as to why white Southerners left the Democratic Party and joined the GOP during the second half of the 20th century.
Much of the academic research to date points to two driving factors: 1) the Democratic Party’s support for 1960s civil rights legislation and 2) economic development within the region, which resulted in white people making more money and turning away from the political party that supports economic redistribution policies.
Research showing that civil rights legislation was the motivating factor has tended to rely more heavily on qualitative data while a lot of the research suggesting other factors played a leading role rely more on quantitative analyses, the authors explain. This study, based on newly available poll data, takes a quantitative approach and finds that anti-black attitudes were the primary reason for the shift.

At RNC, GOP echoes racial code of Nixon's 1968 campaign
SAVANNAH, Ga. (AP) — The question was how he planned to address poverty. In his reply, the Republican running for president quickly pivoted to a central campaign theme — denouncing the fiery chaos that had erupted in American cities during protests over civil rights.

And the one thing the video really didn't get into is that Empacation was never about righting a wrong. It was about political means.It is now in President Donald Trump’s hands.
At his nominating convention this week, Trump’s party has repeatedly warned of lawlessness on America’s streets, pointing to the sometimes violent protests over police killings of Black Americans. The party gave a platform to a St. Louis couple made famous for waving guns at a Black Lives Matter protest outside their home. The president’s son, Donald Trump Jr., described the race between Trump and Democrat Joe Biden as “shaping up to be church, work and school versus rioting, looting and vandalism.”
On Wednesday, Vice President Mike Pence declared, “you won’t be safe in Joe Biden’s America.”
Historians and political observers say the lineage of this messaging is clear. The question isn’t whether Trump is employing the same tactics that helped Nixon seize the White House from Democrats, but whether those tactics can work at this moment — in a more diverse America, beset by a pandemic and weighing whether to reelect a Republican incumbent.
“Trump has dusted off the old playbook that puts racial fear and grievance on the table,” said Otis Johnson, who served from 2004 to 2012 as the second Black man elected mayor of Savannah, Georgia. He was a graduate student in Atlanta when Nixon ran in 1968. Trump’s tactics, he said, are “just a replay for me of 50 years ago.”
But manipulating racial divisions to unite white voters goes back much further in American politics. Before the Civil War, ominous warnings of potential slave uprisings were used to get poor Southern white people to vote in solidarity with wealthier landowners, said Keith Gaddie, a political scientist at the University of Oklahoma.
