The Lower Rio Grande Valley (Spanish: Valle del Río Grande), commonly known as the Rio Grande Valley or locally as the Valley or RGV, is a region spanning the border of Texas and Mexico located in a floodplain of the Rio Grande near its mouth.[1] The region includes the southernmost tip of South Texas and a portion of northern Tamaulipas, Mexico. It consists of the Brownsville, Harlingen, Weslaco, Donna, Pharr, McAllen, Edinburg, Mission, San Juan, and Rio Grande City metropolitan areas in the United States and the Matamoros, Río Bravo, and Reynosa metropolitan areas in Mexico.[2][3] The area is generally bilingual in English and Spanish, with a fair amount of Spanglish[4] due to the region's diverse history and transborder agglomerations.[5] It is home to some of the poorest cities in the nation, as well as many unincorporated, persistent poverty communities called colonias.[6][7] A large seasonal influx occurs of "winter Texans" — people who come down from the north for the winter and then return north before summer arrives.[8]
History
Pre-Spanish colonization
Native peoples lived in small tribes in the area before the Spanish conquest.[9] The native tribes in South Texas were known to be hunter-gatherer peoples.[10] The area was known for its smaller nomadic tribes collectively called Coahuiltecan.[10] Native archaeological excavations near Brownsville have shown evidence of prehistoric shell trading.[11]
Spanish colonization
Initially, the Spanish had a hard time conquering the area due to the differences in native languages, so they mainly focused on the coast of the Gulf of Mexico also known as the Seno Mexicano.[12] Also, a major conflict existed on who would conquer the region. Antonio Ladrón de Guevara wanted to colonize the region, but the Viceroy of New Spain José Tienda de Cuervo doubted Ladrón de Guevara's character, eventually leading to a royal Spanish declaration preventing Ladrón de Guevara from participating in colonization efforts.[13]
Republic of Texas and annexation by the United States
The Texas Revolution of 1835-1836 put the majority of what is now called the Rio Grande Valley under contested Texan sovereignty.[5] The area also became a thoroughfare for runaway slaves fleeing to Mexico.[16]
In 1844, the United States under President James K. Polk annexed the Republic of Texas, against British and Mexican sentiments,[17] contributing to the onset of the Mexican–American War.[17] The area along the Rio Grande was the source of several major battles, including the Battle of Resaca de la Palma near Brownsville.[18] The war ended in 1848 with the signing of the Treaty of Guadalupe Hidalgo which defined the United States' southern border as the Rio Grande. The change in government led to a mass migration from Tamaulipas to the United States side of the river.[12]
From the end of the Mexican-American War, the population of the Valley began to grow, and farmers began to raise cattle in the area.[12] Despite the end of the formal war in 1848, interracial strife continued between native peoples and the white settlers over land through the 1920s.[9][19]
Early 1900s and the Mexican Revolution
At the turn of the 20th century trade and immigration between Mexico and the United States was a normal part of society.[2] The development of the St. Louis, Brownsville, and Mexico Railway in 1903 and the irrigation of the Rio Grande allowed the Rio Grande Valley to develop into profitable farmland.[20] Droughts in the 1890s and early 1900s caused smaller farmers and cattle ranchers to lose their lands. Rich white settlers brought by the railroad bought the land and displaced the Tejano ranchers.[21]
Meanwhile, across the river, Mexico was dealing with the Mexican Revolution.[20] The revolution spilled over the border through cross-border supply raids, and in response President Taft sent the United States Army into the region beginning in 1911 and continuing until 1916 when the majority of the United States armed forces were stationed in the region. Texas governor Oscar Colquitt also sent the Texas Rangers into the area to keep the peace between Mexicans and Americans.[2]
The region played host to several well-known conflicts including the backlash from the Plan of San Diego, and the racially fueled violence of Texas Ranger Harry Ransom.[2] In 1921 the United States Border Patrol came to the region with less than 10 officers.[22] Initially the agency was focused on import and export business, especially alcohol during Prohibition in the United States, but later moved to detaining illegal aliens.[23]
The region had a significant increase of Border Patrol agents during World War I in conjunction with the Zimmermann Telegram.[24] The Texas Rangers also increased their presence as law enforcement in the region with a new class of Ranger that focused on determining Tejano loyalty.[25] They were often violent, carrying out retaliatory murders.[24] They were never held accountable to the law even though charges were brought in the Texas senate.[26]
The North American Free Trade Agreement, also known as NAFTA, was established in 1994 as a trade agreement between the three North American countries, The United States, Mexico, and Canada. NAFTA was supposed to increase trade with Mexico as they lowered or eliminated tariffs on Mexican goods.[28] Exports and imports tripled in the region and accounted for a trade surplus of $75 billion.[28] The Rio Grande Valley benefited from NAFTA in retail, manufacturing, and transportation. Due to the influx of jobs and exportation, many people migrated to the RGV, both documented and undocumented.[29] According to Akinloye Akindayomi in Drug violence in Mexico and its impact on the fiscal realities of border cities in Texas: evidence from Rio Grande Valley counties, NAFTA also indirectly aids the rise in immigration and drug smuggling practices between cartels in the region, with cartels profiting with over $80 billion.[29] The Trump Administration decided to make new accords with Mexico and Canada and replaced NAFTA with the new trade agreement, United States–Mexico–Canada Agreement (USMCA) in 2018.[30]
After the September 11 attacks, the Customs Border Security Act of 2001 established United States Border Patrol interior checkpoints with some situated at the north end of the Rio Grande Valley. This allows for a second line of defense in the ever increasing subtlety of smuggling.
The Rio Grande Valley is not a true valley, but a river delta. "Valley" is often used in the western United States to refer to a large expanse with rivers. Most such valleys, including the Rio Grande, have good agricultural production.[33][1] Early 20th-century land developers, attempting to capitalize on unclaimed land, utilized the name "Magic Valley" to attract settlers and appeal to investors. The Rio Grande Valley is also called El Valle, the Spanish translation of "the valley", by those who live there.[34] The main region is within four Texan counties: Starr County, Hidalgo County, Willacy County, and Cameron County.
As of 2020, the U.S. Census Bureau estimated the population of the Rio Grande Valley at 1,368,723. Hidalgo County has the largest population with an estimate of 861,137.[36] Cameron County has the second-highest population estimated at 422,135. Starr County has the third-largest population estimated at 64,032. Willacy County has the fourth-largest population estimated at 21,419.[36]
According to the U.S. Census Bureau in 2008, 86 percent of Cameron County, 90 percent of Hidalgo County, 97 percent of Starr County, and 86 percent of Willacy County are Hispanic.[37]
Colonias
The major metropolitan areas in the Rio Grande Valley are surrounded by smaller rural communities called colonias.[38] These communities are primarily poor and Hispanic.[39] The areas often lack basic services like sanitation and sewage, and suffer from flooding.[40][38] Many of these colonias are mixes of mobile homes and self-constructed houses owned by the residents.[41] The Bracero program enacted in the 1940s allowed Mexicans to cross the border and work in the agricultural fields. Most worked in the Rio Grande Valley, and due to a shortage of affordable houses, developers started selling them land in unincorporated areas; these clusters of homes over time became what are now known as colonias.[38] According to the Housing Assistance Council, a nonprofit organization that tracks rural housing, approximately 1.6 million people live in 1,500 recognized colonias alongside the Mexico–United States border.[38]
Language use
The residents of the Lower Rio Grande Valley are generally bilingual in English and Spanish often mixing into Spanglish depending on demographics and context.[39][42] Government statistics for the region are often underreported due to underlying immigration issues.[43]
The Spanish language plays an important role in all aspects of life. In 1982 a statistically significant majority of people in the Rio Grande Valley spoke Spanish.[44] People speak Spanish to communicate in all aspects of life including business, government, and at home.[42]

People often prefer Spanish to English when interacting with government officials as seen in the response to the region's 2018 flooding.[46]
One of the offshoots of the Catholic Church, worship of Santa Muerte, has a small but significant following in the valley. There has been public outcry against followers erecting shrines at their homes and in public places.[48][49] In 2015, a Santa Muerte statue was involved with a bomb scare in San Benito, Texas.[50] This followed the desecration of a Santa Muerte statue in the San Benito Municipal Cemetery in January of the same year.[51][49]
The Lower Rio Grande Valley experiences a warm and fair climate that brings visitors from many surrounding areas.[8] Temperature extremes range from triple digits during the summer months to freezing during the winter.[59] While the Valley has seen severe cold events before, such as the 2004 Christmas snow storm and 2021 cold snap, the region rarely experiences temperatures at or below freezing, especially by the coast, which transitions into a Tropical climate.[59]
The ancestral lands of the Rio Grande Valley have been home to historic Native groups, which today include the Carrizo/Comecrudo tribe of Texas.[61] While not recognized under the government, this tribe and other communities have existed on the lands predating European settlement and the acquisition of Texas from Mexico. The tribe speaks of their existence as a way of life.[61] Today, a working map of Native and Indigenous nations and tribes across Turtle Island and the Northern Americas has been communally constructed on the Native Land webpage.[62] The Carrizo/Comecrudo tribe is recognized on the Native Land webpage, represented across South Texas.[63] The visibility and recognition of Native communities like the Carrizo/Comecrudo are paramount and require a constant fight by many Indigenous tribes worldwide, especially when histories of vulnerable groups like Indigenous communities are essentially contested and being attacked legally by state governments.[64]
As historian and scholar Ned Blackhawk outlines in "The Centrality of Dispossession: Native American Genocide and Settler Colonialism," in World History of Genocide: Volume II, the "mythologies of Indigenous ‘disappearance’ appear as ahistorical as they are problematic."[65] Scholars like Blackhawk work to address the narrative of Native peoples as passively disappeared and of existing solely in the past by amplifying the intentional and strategic projects of dispossession and settler colonialism in their goals to erase, harm, and destabilize a group of people. Therefore, the Carrizo/Comecrudo tribe's work to establish their presence and continually advocate for their way of living and place in the Rio Grande Valley is resilient and vital.
The Carrizo/Comecrudo tribe of Texas has long fought with SpaceX over the environmental protection of their lands. Elon Musk established Starbase, one of the engineering hubs, in Boca Chica Beach, a coastal beach of the Rio Grande Valley.[66] Alongside the Carrizo/Comecrudo tribe of Texas, local RGV environmental organizations have opposed SpaceXs business and activities at Boca Chica, citing the tribe's claims to land and destruction to the local terrain and natural life.[67]
On August 5, 2024, a group of local organizations including the Carrizo/Comecrudo tribe wrote a letter to the Federal Aviation Administration raising concerns about SpaceX operations in Boca Chica Beach and requesting a meeting to discuss the FAA's process of incorporating community voice into the conversation.[67] The group includes a range of environmental organizations across the Rio Grande Valley, including the South Texas Environmental Justice Network, the South Texas Human Rights Center, TRUCHA, Voces Unidas, and Texas Rising RGV. The letter highlights the identities of Rio Grande Valley community members that are most often overlooked, including Indigenous voices. Now, there are large concerns regarding Elon Musk’s intentions to relocate the headquarters of SpaceX to the Starbase site in Boca Chica Beach.[68]
The Valley is historically reliant on agribusiness and tourism. Cotton, grapefruit, sorghum, maize, and sugarcane are its leading crops, and the region is the center of citrus production and the most important area of vegetable production in the State of Texas. Over the last several decades, the emergence of maquiladoras (factories or fabrication plants) has caused a surge of industrial development along the border, while international bridges have allowed Mexican nationals to shop, sell, and do business in the border cities along the Rio Grande. The geographic inclusion of South Padre Island also drives tourism, particularly during the Spring Break season, as its subtropical climate keeps temperatures warm year-round.[70] During the winter months, many retirees (commonly referred to as "Winter Texans") arrive to enjoy the warm weather,[8] access to pharmaceuticals and healthcare in Mexican border crossings such as Nuevo Progreso.[71] There is a substantial health-care industry with major hospitals and many clinics and private practices in Brownsville, Harlingen, and McAllen.
Texas is the third largest producer of citrus fruit in the United States, the majority of which is grown in the Rio Grande Valley. Grapefruit make up over 70% of the Valley citrus crop, which also includes orange, tangerine, tangelo and Meyer lemon production each Winter.[72]
One of the Valley's major tourist attractions is the semi-tropical wildlife. Birds and butterflies attract a large number of visitors every year all throughout the entire region. Ecotourism is a major economic force in the Rio Grande Valley.[73][74]
There are several bus lines that run through the United States side of the Lower Rio Grande Valley including Metro Connect (McAllen), McAllen Paratransit, McAllen Metro Services, Brownsville Metro/ADA Paratransit Service Island Metro (South Padre Island), and Greyhound Lines.[81][82] On the Mexican side of the border there are several bus companies that run including Greyhound, Tornado, Ave Senda Ejecutiva, Enlaces Terrestres Nacionales, Futua, Noreste, Omnibus de Oriente, Transpais, Transportes del Norte, Transportes Frontera, and Turistar Lujo.[83][82]
Democratic candidate Beto O'Rourke received 164,232 votes from the region, compared to incumbent Ted Cruz's 79,049, in his failed bid to replace Cruz in the Senate in 2018.[91]
Unlike most of Texas, the Rio Grande Valley is strongly Democratic, having last voted for a Republican presidential candidate in 2024 and only 4 times since 1912, along with 1952, 1956, and 1972.
In 2016, Donald Trump won only 29 percent of the region's vote, an 80-year low for Republicans. However, in 2020, he significantly strengthened the Republican vote in the Rio Grande Valley, reducing, among other things, Hillary Clinton's 2016 60-point margin of victory in 96% Hispanic Starr County to only 5 points.[92][93][94]
Education
Historically, education has posed significant challenges to schools in the region. Schools in the early 1920s through the 1940s were racially segregated in the Rio Grande Valley. In 1940 a study showed the need for improvement in cultural differentiation of instruction.[95] The Texas Supreme Court in Del Rio ISD v. Salvatierra reinforced the racial segregation.[96] In 1968, President Lyndon B. Johnson signed the Bilingual Education Act, helping students whose second language was English. The Act gave financial assistance to local schools to create bilingual programs, enabling Mexican students to integrate white schools.[96] The area, like many others, had a hard time integrating.[97] Texas still has the bilingual program, while states like California, Arizona, and Massachusetts, have removed the bill and passed similar propositions stating that students would only be taught in English.[96] The bilingual program in the Rio Grande Valley is still in effect, especially with Deferred Action for Childhood Arrivals students in the area.[96]
