Harrisburg is a community that is now (originally documented as Harrisburgh then shortened to Harrisburg in 1892) located within the city of Houston, Texas, United States.
The community is located east of Downtown Houston, south of the Brays Bayou and Buffalo Bayou junction, and west of Brady's Island. It was founded before 1825 on the eastern stretches of the Buffalo Bayou in present-day Harris County, Texas, on land belonging to John Richardson Harris. In 1926, Harrisburg was annexed into the city of Houston. The original name of Harris County was Harrisburg (Harrisburgh) County until it was shortened after the demise of the City of Harrisburg.
Harrisburg was surveyed in 1826 and formally named Harrisburg by its founder, John Richardson Harris. Harris named the town both after himself and after Harrisburg, Pennsylvania, which had been named for his great-grandfather.
John Kirby Allen and Augustus Chapman Allen wanted to found a new city on a water area upstream from the Galveston Bay. The location of Harrisburg, which had been platted by Harris in 1826, was the Allen Brothers' first choice. The brothers could not buy Harrisburg since Harris was dead, and no clear title to the land existed. The brothers founded Houston in an area which was the brothers' second choice.
In 1835, the General Council of Texas, a provisional government of Texas, made Harrisburg its capital. On April 16, 1836 during the Texas Revolution, almost all of Harrisburg was burned by the forces of Antonio López de Santa Anna. After the Texas Revolution ended, the city of Houston was founded just west of Harrisburg and was named county seat of Harrisburg (later shortened to Harris) County and capital of the Republic of Texas.
