Six wards of Houston
When the city of Houston was founded in 1836 and incorporated in 1837, its founders—John Kirby Allen and Augustus Chapman Allen—divided it into political geographic districts called "wards". The ward system, a precursor to today's City Council districts, was a common political tool of the early 19th century, and is still used in some American cities. When the system was at its peak, the city had six wards, from the first to the sixth.
In 1840, the Republic of Texas altered the city charter for Houston, dividing it into four wards. Historically the wards reflected geographic boundaries, without consideration of the population density within the wards. After slavery ended in Texas on June 19, 1865, ex-slaves were forced to live in separate enclaves within each of Houston’s wards. The voting population of the wards was lower than the population, since women and African-Americans had been forbidden from voting. Instead, wards followed boundaries of features such as the Buffalo Bayou, Congress Street, and Main Street. Each ward elected two aldermen to the Houston City Council. The election of the Mayor of Houston was citywide. Betty Chapman, a historian, said "They really were mixed societies in the early days. Where you worked dictated where you lived, not who you wanted to live around."
The ward boundaries touched each other at the intersection of Congress Street and Main Street. The first ward was northwest of that intersection. The ward housed the city's market house and produce industry facilities. The second ward was located to the northeast. The courthouse and the heavy warehouses were located there. Therefore many lawyers and merchants resided there. The third was situated to the southeast. Businesspeople, craftsmen, and professionals lived there. The Third Ward had fancier houses than other wards. The fourth ward was southwest of the intersection. That ward included what was then the central portion of the city. Freed slaves developed Freedmen's Town in a 5 square miles (13 km2) area in the Fourth Ward.
By December 1866, the Fifth Ward had been created, with two aldermen elected from that area during that month. The Fifth Ward was added in 1866 to accommodate the city's growth. Buffalo Bayou served as the ward's southern border, while the White Oak Bayou served as the ward's western border. The idea was not to have an equal number of residents in each but rather to draw lines along natural boundaries: Buffalo Bayou, Main Street, and Congress Street. In 1876 the city created the Sixth ward. It was bounded by the First Ward's southwest boundary and the Buffalo Bayou.
