Following the defeat of the Confederate States in the American Civil War, Texas was mandated to rejoin the United States of America. Union Army soldiers officially occupied the state starting on June 19, 1865. For the next nine years, Texas was governed by a series of provisional governors as the state went through Reconstruction. As stated by the Texas State Library and Archive Commission, in 1869, the United States Congress passed an act allowing the citizens of Texas to vote on a new State Constitution. Later that same year, President Grant approved their Constitution. Texas fully rejoined the Union on March 30, 1870, when President Grant signed the act to readmit Texas to Congressional Representation. Texas later repealed the State Constitution of 1869 and enacted the Texas State Constitution of 1876 on February 15, 1876, which remains their current state constitution though with numerous amendments.''
Much of the politics of the remainder of the century centered on land use. Guided by the federal Morill Act, Texas sold public lands to gain funds to invest in higher education. In 1876, the Agricultural and Mechanical College of Texas opened, and seven years later the University of Texas at Austin began conducting classes. New land use policies drafted during the administration of Governor John Ireland enabled individuals to accumulate land, leading to the formation of large cattle ranches. Many ranchers ran barbed wire around public lands, to protect their access to water and free grazing. This caused several range wars. Governor Lawrence Sullivan Ross guided the Texan legislature to reform the land use policies.
The state continued to deal with the issues of racism, with hundreds of acts of violence against blacks as whites tried to establish white supremacy. Ross had to personally intervene to resolve the Jaybird-Woodpecker War.
In March 1890, the U.S. Attorney General launched a suit in the Supreme Court against Texas to determine ownership of a disputed plot of land in Greer County. Determined to meet personally with the Attorney General, Ross and his wife traveled to Washington, D.C., where they visited President Benjamin Harrison at the White House. Following that visit, they traveled to New York, where they met with former president Grover Cleveland. While in New York, Ross was extremely popular with journalists. He was interviewed by several large northeastern newspapers, which recounted in detail many of his exploits along the frontier. According to his biographer Judith Brenner, the trip and the resulting exposure for Ross, "excited much interest in Texas among easterners, an interest that would eventually bear fruit in increased investment, tourism, and immigration".
Racial issues
The Freedmen's Bureau was set up to help manage the transition for freedmen and oversee their labor contracts under the free labor system. During Reconstruction, incidents of white violence against blacks increased as whites struggled to reassert white supremacy. By the late 1870s, the Democratic-dominated legislature passed laws to impose legal segregation in public facilities and other Jim Crow laws. Nonetheless, freedmen organized, joined the Republican Party, and started to participate in politics.
During his second term, Ross was forced to intervene in the Jaybird-Woodpecker War in Fort Bend County. Sheriff Jim Garvey (a Woodpecker) feared that there would be armed battles between the State's Rights Democrats (the Jaybirds) and the black Federalist Republicans who had retained political power for 22 years. At Garvey's request, Ross sent two militia companies, which managed to impose a four-month peace. In August 1889, Ross sent four Texas Rangers, including Sergeant Ira Aten, to quell the unrest. Violence erupted, leaving four people dead and injuring six, including a Ranger. Aten wired Ross for help. The following morning, the Houston Light Guard arrived and instituted martial law; that evening, Ross arrived with an Assistant Attorney General and another militia company. Ross fired all the local Woodpecker and Republican civil officials and called together representatives from both factions. On his suggestion, the two groups agreed to choose a mutually acceptable sheriff to replace Garvey, who had been killed in the firefight. When they could not agree on a candidate, Ross suggested Aten; both groups finally agreed, thus halting the conflict.
