Prior to Europeans settling on the area near Galveston Bay, various native tribes like the Akokisa had inhabited it. Following the declaration of Mexican independence from Spain, Mexico offered land grants to settlers from both Mexico and the United States in order to colonize Texas, its northernmost territory. This brought in a rapid wave of settlement around the Galveston Bay area.
After a coup in the Mexican government in 1835, Texas revolted against Mexico. The last battle of the Texas Revolution took place in 1836, near modern-day Pasadena. Due to this being the final conflict leading to the Mexican surrender, Pasadena has adopted the nickname the “Birthplace of Texas.”
The year 1900 saw The Great Galveston hurricane, the deadliest natural disaster in United States history at the time, bring heavy damage to Pasadena, and destroying Galveston completely. Many Galveston refugees moved to Pasadena, and amongst the vast donations from the newly created Red Cross were millions of strawberry plants, leading to Pasadena becoming a major producer of fruit.
The following year saw the beginning of the Texas Oil Boom, and the discovery of an oil field in nearby Goose Creek. This lead to ever petroleum exploration around the area, and by 1917 to 1920, refinery operations had made their way to Pasadena. The onset of World Wars I and II helped spur increased industrial development in the region, and Pasadena surpassed even Houston in terms of growth rate.
Pasadena voted in 1923 to incorporate, however in the following year residents decided to cancel the process. It was not until 5 years later in 1928 that Pasadena finally did incorporate, and as a result of this was not incorporated into Houston when it annexed surrounded unincorporated areas.
