After the Civil War, Reconstruction of the Union brought the creation of the Freedmen's Bureau in 1865 and the Civil Rights Act of 1866 and Reconstruction Act of 1867, while Texas did not officially re-enter the Union until March 30, 1870, because it had refused to ratify the 13th Amendment abolishing slavery and the 14th Amendment granting citizenship to African Americans. At the 1866 Constitutional Convention, Texans imposed Black Codes that limited Black Americans' autonomy by barring access to public facilities, imposing curfews, disallowing firearms possession, and forbidding objectionable public behavior. In the 1870's, Black people were given the right to vote, but in Texas that right was hindered by poll taxes, reading comprehension tests, complicated ballots, and the belief among many Whites that only educated landowners should vote. By the 1890's, segregation had become the norm after Plessy vs. Ferguson in 1896 upheld equal but separate accommodations for white and colored races. In Hunt County, Reconstruction was marked by violence, especially the Lee-Peacock Feud between Unionist Lewis Peacock of Grayson County and ex-Confederate Bob Lee of Hunt County, which lasted from 1867-1871 in the thicketed region where Grayson, Fannin, Hunt, and Collin counties met, drew attention as far as Washington D.C., led to two companies of federal cavalry being stationed in Greenville in 1868, and ended after killings on both sides with Bob Lee's death near present-day Leonard in 1869 and Lewis Peacock's shooting on June 13, 1871; fifty men were killed and many others injured. During this period, Hardin Hart, born in West Virginia on August 23, 1814, served in the Texas Senate from 1849-1855 and after the Civil War was appointed District Judge of the Sixteenth Judicial District in Denton, where in 1867 he ruled the stay of execution law unconstitutional in all civil and criminal cases; he also became involved in the feud after confronting Bob Lee over the treatment and pay of freedmen, survived an assassination attempt on November 13, 1868, lost an arm from his wounds, and died on October 5, 1883. Hunt County's economy also shifted with the arrival of the Missouri, Kansas, and Texas Extensions Railway in Greenville in the fall of 1880, followed by more railways that helped transform the county into a more diverse and connected place as its population grew to nearly seven times its size at the beginning of the Civil War.
