Continued violence in the South, especially heated around electoral campaigns, sapped Northern intentions. More significantly, after the long years and losses of the Civil War, Northerners had lost heart for the massive commitment of money and arms that would have been required to stifle the white insurgency. The financial panic of 1873 disrupted the economy nationwide, causing more difficulties. The white insurgency took on new life ten years after the war. Conservative white Democrats waged an increasingly violent campaign, with the Colfax and Coushatta Massacres in Louisiana in 1873 as signs. The next year saw the formation of paramilitary groups, such as the White League in Louisiana (1874) and Red Shirts in Mississippi and the Carolinas, that worked openly to turn Republicans out of office, disrupt black organizing, and intimidate and suppress black voting. They invited press coverage. One historian described them as "the military arm of the Democratic Party."
