In the 1830s, new communities such as Houston were established along the shoreline. A local entrepreneur named Samuel Allen (unrelated to the founders of Houston) established a large ranch, later known as the Allen Ranch, between Harrisburg and Galveston Bay. Docks at Harrisburg, Houston, and the Allen Ranch gradually became the foundations of what would become the modern Port of Houston. Harrisburg served as the region's major trade center until the 1870s, when a large fire destroyed its railroad facilities, which were subsequently rebuilt in Houston.
