Indisputably, for much of American history, gun-control measures, like many other laws, were used to oppress African Americans. The South had long prohibited blacks, both slave and free, from owning guns. In the North, however, at the end of the Civil War, the Union army allowed soldiers of any color to take home their rifles. Even blacks who hadn’t served could buy guns in the North, amid the glut of firearms produced for the war. President Lincoln had promised a “new birth of freedom,” but many blacks knew that white Southerners were not going to go along easily with such a vision. As one freedman in Louisiana recalled, “I would say to every colored soldier, ‘Bring your gun home.’”
