For a period of over 7000 years, humans have inhabited the Galveston Bay Area in what is now the United States. Through their history the communities in the region have been influenced by the once competing sister cities of Houston and Galveston, but still have their own distinct history. Though never truly a single, unified community, the histories of the Bay Area communities have had many common threads.

Prior to European settlement the area around Galveston Bay was settled by the Karankawa and Atakapan tribes, who lived throughout the Gulf coast region. Spanish and French explorers traveled the area for many years gradually establishing trade with the local natives. In the early 19th century the pirate Jean Lafitte created a small, short-lived empire around the bay ruled from his base on Galveston Island before his being ousted by the United States Navy.

Following Mexico's independence from Spain, the new nation established long-term settlements, including Anahuac and San Jacinto, around the bay. Early settler revolts against Mexican rule occurred in the region, home to the final Texan Victory over the Mexican army during the Texas Revolution.

Following Texas' independence from Mexico and its annexation by the United States, economic growth was centered initially on agriculture and cattle ranching. Commerce grew between Galveston, Harrisburg and Houston in the later 19th century, and created additional economic opportunities as railroads were built through the Bay Area to connect these and other commercial centers.

In the early 20th century, the region gave birth to some of the state's earliest oil fields and refineries as the Texas Oil Boom took hold. Refining and manufacturing grew rapidly in the area, particularly around Baytown, Pasadena, and Texas City. The opening of the Port of Texas City, and later Barbours Cut and Bayport, gradually established the region as an important shipping center. As wealth increased in southeast Texas, resorts and other tourist draws developed in the Bay Area. During the 1960s the area became home of the Johnson Space Center, headquarters for the nation's crewed space program, which helped diversify the regional economy and began the development of an aerospace industry, and later other high-tech industries.

Early history

The present geography of the Gulf Coast was formed during an ice age approximately 30,000 years ago when dramatic lowering of the sea level occurred. As the ice later melted, it formed a flow through the Trinity and San Jacinto rivers and carved wide valleys in the soft sediments, resulting in the creation of the modern system of bays and lakes approximately 4,500 years ago.

Humans first entered the region as early as 10,000 years ago following migrations into the Americas from Asia during the ice age. Research has indicated that the first settlements around Galveston Bay may have been constructed around 5500 BCE. The first ceramics appeared around 100 CE, and arrow points around 650 CE. When Europeans first entered the region there were still significant numbers of Native Americans living there. Texas State Historical Association. Texas State Historical Association. Along the southern coast around the Colorado River and Matagorda Bay and up toward Galveston Bay lived the Capoque tribe, a branch of the Karankawa people. The northeast was inhabited by the Akokisa, or Han, tribe as part of the Atakapan people's homelands. The Karankawa were migratory hunter-gatherers. Their diet included deer, bison, peccary, and bears, in addition to fish, oysters, nuts, and berries as they were available. They used portable huts for shelter. Dugout canoes were used to travel the many internal waterways and the coast, an advantage that initially gave them tactical superiority over the Europeans. The Akokisa in the area were similarly hunter-gatherers, and utilized canoes for transport. They became well known among the Europeans for their hide-tanning abilities, especially for bear hide. During the 18th century the Akokisa population in the area was estimated at about 3,500.

Though earlier surveys of the coastline had been made, the first known Europeans to land in the vicinity were under the command of Spanish explorer Álvar Núñez Cabeza de Vaca when he and his crew were shipwrecked in 1528, though it is unclear precisely where they landed. Though subsequent explorers described cannibalism among the local tribes, Cabeza de Vaca made no mention of the practice. He and the other survivors left the area as soon as they were able traveling to safety into Mexico. Texas State Historical

The Rivas-Iriarte expedition, one of several Spanish maritime expeditions charting the Gulf Coast, performed a detailed scientific exploration of the Galveston Bay in 1687, probably the first such exploration. Texas State Historical Association A 1785 expedition by José Antonio de Evia charting the Gulf Coast gave the bay and the island the name Galveztown, or Galvezton, for the Spanish Viceroy Bernardo de Gálvez.

During the early 18th Century, French traders first began trade with the Akokisa and the nearby Bidai tribes for furs. In 1754 several traders including Joseph Blancpain established a trading post on the Trinity River a just north of the bay, near modern Wallisville. Spanish authorities quickly seized the post and transformed it into the San Augustín de Ahumada fort. They named the site El Orcoquisac and established a Catholic mission. The Spanish were not successful in maintaining trade with the natives and the post was abandoned within a few years. Encroachment by Spanish as well as U.S. settlers continued such that by the end of the century native populations had declined dramatically due to disease and territorial pressures from the Europeans.

In 1816 Galveston Island was claimed by the pirate Louis-Michel Aury as a base of operations to support Mexico's rebellion against Spain. Aury was succeeded as leader by Jean Lafitte, the famed Louisiana pirate and American hero of the War of 1812. Lafitte, at the time serving as a privateer for the Spanish Empire, transformed Galveston Island and the bay into a pirate kingdom he called Campeche. He established bases for smuggling and ship repair on the Trinity River near the bay and at Eagle Point (modern San Leon). His gang also created a hide-out on the shores of Clear Lake. As late as 1965, treasure from this era was discovered at Kemah.Chang (2006), p. 187Kearney (2008), p. 177 In response to the piracy, the United States Navy ousted Lafitte from the island in 1821 and the colony was abandoned. Texas State Historical Association. Some settlers in the region remained such as Anson Taylor who had supplied produce and game from the Clear Lake area for Campeche.

Mexican dominion and the Republic of Texas

In the early 19th century following the Louisiana Purchase, Texas, particularly southeastern Texas, had become an increasing point of contention between Spain and the United States. Various failed attempts, such as the Long Expedition, were made by groups from the U.S. to take control of parts of Texas, resulting in some temporary settlements near the bay including Perry's Point near modern Anahuac. Texas State Historical Association. Texas State Historical Association. Spanish authorities began efforts to colonize Texas to help protect its claim to the territory. Hoping to spur settlement, the Spanish government granted land to pioneers from the United States, including Moses Austin. Texas State Historical Association.

Soon afterward, though, Mexico declared its independence from Spain and moved to establish its own control over Texas. Because of fears of the indigenous tribes, officials found it difficult to find settlers in Mexico willing to move into the territory's coastal areas, and therefore continued to allow settlers from the United States into the area with the promise of allegiance to Mexico. Austin's son, Stephen F. Austin, established a colony which extended from east central Texas to Galveston Bay and the Gulf Coast. Some of Austin's original Old 300 settlers, including John Dickson, William Scott, and John Iiams, established homesteads and commercial enterprises around the bay. Texas Historical Association. Texas Historical Association. Texas Historical Association. The Port of Galveston and a permanent settlement were established on the island in 1825 to spur trade. Texas State Historical Association Communities including Lynchburg, San Jacinto, and Campbell's Bayou (founded by one of Lafitte's former officers) were gradually established around the bay. In addition to the Anglo-American and Mexican settlers in the area, a Cajun settlement was established along Armand Bayou. Texas State Historical Association. The Mexican Colonization Law of 1824, however, forbade the creation of settlements near the coast with the intention of protecting the native tribes in the area.Sage (2002), p. 27. Texas State Historical Association The law was not enforced and settlers continued to encroach upon tribal lands. Native tribes remained in the area years afterward but were gradually driven out as European settlers moved into the region. The Akokisa were driven inland where they merged with the Bidai. The Karankwa were driven southward where they eventually established their current homelands in northeastern Mexico.

The Galveston Bay and Texas Land Company was formed in New York in 1830 to promote additional settlement around Galveston Bay and other parts of southeast Texas. Texas State Historical Association.Barker (1969), pp. 277–278. The company gradually brought in many colonists from the United States and Europe, although conflict with Mexican officials over colonization laws initially made these efforts difficult. In 1830, Mexican authorities created a customs and garrison post near the bay commanded by Juan Davis Bradburn.Rodríguez (1997), p. 63–65. The post, which later became the modern city of Anahuac, was the first major outpost on the mainland shores and temporarily replaced Galveston as a port of entry.Sage (2002), p. 27–28. New Washington (modern Morgan's Point) and Austinia (within modern Texas City) were also founded by settlers from the company. Texas State Historical Association. Texas State Historical Association. Conflicts between Bradburn and the settlers in the region over land rights, slavery laws, and customs duties led to the Anahuac Disturbances, a prelude to the larger Texas rebellion. As a result, Mexican authorities were driven out of eastern Texas and the settlers began to discuss independence. Texas State Historical Association.

Following a coup in the Mexican government, Antonio Lopez de Santa Anna became president and revoked many freedoms previously enjoyed by the Texans further deteriorating the government's relations with the region's settlers. Texas State Historical Association. Texas declared its independence and revolted in 1835. Following a number of battles with the Mexican army, the Texas army, under the leadership of General Sam Houston, finally defeated Santa Anna in the Battle of San Jacinto, near modern Pasadena.
