Ciudad Juárez in the context of "El Paso, Texas"

The international boundary separating Mexico and United States extends from the Pacific Ocean to the Gulf of Mexico. The border traverses a variety of terrains, ranging from urban areas to deserts. It is the most frequently crossed border in the world, with approximately 350 million documented crossings annually. Illegal crossing of the border to enter the United States has caused the Mexico–United States border crisis. It is one of two international borders that the United States has, the other being the northern Canada–United States border; Mexico has two other borders: with Belize and with Guatemala.

Four American Sun Belt states border Mexico: California, Arizona, New Mexico and Texas. One definition of Northern Mexico includes only the six Mexican states that border the U.S.: Baja California, Chihuahua, Coahuila, Nuevo León, Sonora and Tamaulipas. The total length of the continental border is 3,145 kilometers (1,954 miles). From the Gulf of Mexico, it follows the course of the Rio Grande (Río Bravo del Norte) to the border crossing at Ciudad Juárez, Chihuahua, and El Paso, Texas. Westward from El Paso–Juárez, it crosses vast tracts of the Chihuahuan and Sonoran deserts to the Colorado River Delta and San Diego–Tijuana, before reaching the Pacific Ocean.

Chihuahua, officially the Free and Sovereign State of Chihuahua, is one of the 31 states which, along with Mexico City, are the 32 federal entities of Mexico. It is located in the northwestern part of Mexico and is bordered by the states of Sonora to the west, Sinaloa to the southwest, Durango to the south, and Coahuila to the east. To the north and northeast, it shares an extensive border with the U.S. adjacent to the U.S. states of New Mexico and Texas. The state was named after its capital city, Chihuahua City; the largest city is Ciudad Juárez. In 1864 the city of Chihuahua was declared capital of Mexico by Benito Juárez during the Reform War and French intervention until 1867. The city of Parral was the largest producer of silver in the world in 1640. During the Mexican War of Independence, Miguel Hidalgo was executed on July 30, 1811, in Chihuahua city.

Although Chihuahua is primarily identified with its namesake, the Chihuahuan Desert, it has more forests than any other state in Mexico, aside from Durango. Due to its varied climate, the state has a large variety of fauna and flora. The state is mostly characterized by rugged mountainous terrain and wide river valleys. The Sierra Madre Occidental mountain range, part of the continental spine that also includes the Rocky Mountains, dominates the state's terrain, and is home to the state's greatest attraction, Las Barrancas del Cobre, or Copper Canyon, a canyon system larger and deeper than the Grand Canyon. The state also has the largest crystal cave in Mexico known as the Naica cave discovered in 2001. Chihuahua is also home to the archaeological site of Paquimé in Casas Grandes that was created by the people of the Mogollon culture of Northern Mexico and is recognized as an UNESCO World Heritage site. Chihuahua is the largest state in Mexico by area, with an area of 247,455 square kilometres (95,543 sq mi), it is slightly larger than the United Kingdom, and slightly smaller than Wyoming, the tenth largest US state by area. The state is consequently known under the nickname El Estado Grande ('The Great State' or 'The Big State').

The United States involvement in the Mexican Revolution was varied and seemingly contradictory, first supporting and then repudiating Mexican regimes during the period 1910–1920. For both economic and political reasons, the U.S. government generally supported those who occupied the seats of power, but could withhold official recognition. The U.S. supported the regime of Porfirio Díaz (1876–1880; 1884–1911) after initially withholding recognition since he came to power by coup. In 1909, Díaz and U.S. President Taft met in Ciudad Juárez, across the border from El Paso, Texas. Prior to Woodrow Wilson's inauguration on March 4, 1913, the U.S. Government focused on just warning the Mexican military that decisive action from the U.S. military would take place if lives and property of U.S. nationals living in the country were endangered. President William Howard Taft sent more troops to the US-Mexico border but did not allow them to intervene directly in the conflict, a move which Congress opposed. Twice during the Revolution, the U.S. sent troops into Mexico, to occupy Veracruz in 1914 and to northern Mexico in 1916 in a failed attempt to capture Pancho Villa. U.S. foreign policy toward Latin America was to assume the region was the sphere of influence of the U.S., articulated in the Monroe Doctrine. However the U.S. role in the Mexican Revolution has been exaggerated. It did not directly intervene in the Mexican Revolution in a sustained manner.

During Díaz's long rule, he implemented policies aimed at modernization and economic development, inviting foreign entrepreneurs to invest in Mexico. The regime passed laws favorable to investors. American business interests invested large amounts of capital, particularly along the U.S.-Mexico border, during the decades of Díaz's rule. There was close economic cooperation between the two governments, which was predicated on Diaz's cooperation with US investors. In 1908 Díaz stated he would not run for re-election in 1910; the statement gave rise to politicking of potential candidates. Díaz reversed himself, ran for re-election, and jailed the leading opposition candidate, Francisco I. Madero. Madero escaped Mexico and took refuge in San Antonio, Texas, and called for nullification of the 1910 elections, declared himself as provisional president, and asked for support from the Mexican people. His Plan of San Luis Potosí sparked revolutionary uprisings, particularly in Mexico's north. The U.S. stayed out of the unfolding events until March 6, 1911, when President William Howard Taft mobilized forces on the U.S.-Mexico border. "In effect this was an intervention in Mexican politics, and to Mexicans it meant the United States had condemned Díaz."

The Rio Grande rift is a north-trending continental rift zone. It separates the Colorado Plateau in the west from the interior of the North American craton on the east. The rift extends from central Colorado in the north to the state of Chihuahua, Mexico, in the south. The rift zone consists of four basins that have an average width of 50 kilometres (31 mi). The rift can be observed on location at Rio Grande National Forest, White Sands National Park, Santa Fe National Forest, and Cibola National Forest, among other locations.

The Rio Grande rift has been an important site for humans for a long time, because it provides a north–south route that follows a major river. The Rio Grande follows the course of the rift from southern Colorado to El Paso, where it turns southeast and flows toward the Gulf of Mexico. Important cities, including Albuquerque, Santa Fe, Taos, Española, Las Cruces, El Paso, and Ciudad Juárez, lie within the rift.

Pascual Orozco Vázquez, Jr. (in contemporary documents, sometimes spelled "Oroszco") (28 January 1882 – 30 August 1915) was a Mexican revolutionary leader and general who rose up to support Francisco I. Madero in late 1910 to depose long-time president and dictator Porfirio Díaz (whose eponymous era lasted from 1876 to 1911). Orozco was a natural military leader whose victory over the Federal Army at Ciudad Juárez was a key factor in forcing Díaz to resign in May 1911. Following Díaz's resignation and the democratic election of Madero in November 1911, Orozco served Madero as leader of the state militia in Chihuahua, a paltry reward for his service in the Mexican Revolution. Orozco revolted against the Madero government 16 months later, issuing the Plan Orozquista in March 1912. It was a serious revolt which the Federal Army struggled to suppress. When Victoriano Huerta led a coup d'état against Madero in February 1913 during which Madero was murdered, Orozco joined the Huerta regime. Orozco's revolt against Madero somewhat tarnished his revolutionary reputation, but his subsequent support of Huerta compounded the repugnance against him.

The Bridge is an American crime drama television series, developed by Meredith Stiehm and Elwood Reid, that was broadcast on the FX network, and based on the Danish-Swedish series Bron/Broen. The series stars Diane Kruger and Demián Bichir in leading roles, and co-stars Ted Levine, Annabeth Gish, Thomas M. Wright, Matthew Lillard and Emily Rios in supporting roles. The complete series consists of two seasons of 13 episodes each. The series debuted on FX in the United States on July 10, 2013, and the series finale aired on October 1, 2014. The show was developed both in English and Spanish languages.

The American version takes place on the Mexico–United States border where a murdered body on a bridge between El Paso and Juárez (the Bridge of the Americas) brings together El Paso detective Sonya Cross (Kruger) who is mentored by Hank Wade (Levine) and Chihuahua State police detective Marco Ruiz (Bichir). The story parallels the investigation by El Paso Times reporters Daniel Frye (Lillard) and Adriana Mendez (Rios). The series was a critical success and received positive reviews throughout its run. After the first season maintained a modest audience that dropped by 42 percent by the second, the series was not renewed for a third season.
