Tamaulipas, México




    Tamaulipas, Mexico was first settled by various tribes in 4000 B.C., including the Olmec, Chichimec, and Huastec tribes. In 1445, the Aztecs, commanded by Moctezuma I Ilhuicamina, gained control of the region and maintained control of the land until 1466. During this time the Aztec people failed to completely conquer the Comanche and Apache people.[1]

    Francisco Hernandez de Cordoba led the first Spaniards into Tamaulipas in 1517; however he was defeated by the native Huastec people. [1] The first Spaniard to defeat the indigenous people of Tamaulipas was Hernan Cortes in 1522. Cortes captured the city of Chila, and attempted to convert locals to Catholicism, an effort that ultimately failed. [1] The first Spanish settlement was Tampico, founded in 1554. [2] Settlement of Tamaulipas was furthered by Franciscan priests when they founded missions and began converting members of the indigenous population. During this time, widespread cattle and sheep ranching by the Spanish bolstered the area’s economy while forcing native populations from their original lands.[1]

    Tamaulipas was incorporated as a province of New Spain, named Nuevo Santander, in 1746. Early attempts to bolster the economy and population of Tamaulipas were hindered by a lack of transportation infrastructure. Attempts to build the infrastructure necessary for economic and population growth were made in order to prevent the French from continuing their colonization south into Spanish territory. [1] Following a call for independence in the late 1700s, native rebels of Tamaulipas won important military victories in San Antonio Bejar (present day San Antonio, Texas). By 1750, the region had been greatly influenced by the desire for independence, the invasion of the United States, and the struggle amongst liberals and conservatives, creating a strong sense of autonomy. [2]

    The War of Independence began in 1810 when native inhabitants of Mexico began fighting Spanish Colonists; however, the revolt was stopped by Spanish royalist troops. In 1821, Mexico gained its independence from Spain and in 1824 Tamaulipas joined the Mexican federation of states. [1] In 1840, after suffering at the hand of President Antonio Lopez de Santa Anna, Tamaulipas became a member of the Republic of the Rio Grande along with the states of Nuevo Leon and Coahuila, independent of Mexico. The republic was quickly defeated by the Mexican army. [2]

    From 1850 – 1900 the country was characterized by political instability until President Porfirio Diaz brought economic development to the region. This development continued into the 20th century as Tamaulipas increased commerce with the United States. Tamaulipas became a manufacturing center for products exported to the U.S. after the North American Free Trade Agreement was passed in 1994. [1]

    Drug Violence

    Many of the major issues in Tamaulipas are related to the violence between the drug cartels and the Mexican government. The drug war has claimed over 50,000 lives in Mexico over the past five years, and the majority of the civil unrest in Tamaulipas is driven by the discontent with that violence.[21]

    Protests erupted in Tamaulipas on April 6, 2011, as police began to unearth mass graves which were discovered in the nearby countryside. People took to the streets in 38 cities, bearing signs with the slogan, “Ya Basta”, which simply means “Enough”. In total, police identified 72 corpses from the mass graves. [22] Mexico has suffered from an increase in innocent victims as a result of the drug war, and most of the victims found in the mass grave had no obvious ties to the drug-trade.

    The Movement for Peace with Justice and Dignity was started in response to this very issue. Javier Sicilia, who has been at the forefront of the protests, founded the movement in April 2011 after his son, Juan Francisco, and six other people were murdered by suspected drug-gang members.[23] Reportedly, Juan Francisco and his friends had a loud conversation about the drug war, and all seven were later found dead in a car next to a note that said, “This is what happens to those who make anonymous calls to soldiers.”[22]

    The group has organized several marches to bring together relatives of victims of violence, and it is demanding an end to the deployment of government troops who are attempting to combat the drug cartels. Sicilia proposed that the Mexican government should make a pact with criminal organizations to end violence and the deaths of innocents. However, President Felipe Calderon has made it clear that withdrawing from the fight against the drug cartels is not an option. “On the contrary, we must redouble our efforts because if we stop fighting they will kidnap, rob and kill all over the country.”[24]

    Another protest was organized on May 5, 2011, where demonstrators participated in a silent march against violence. About 200 people attended the “March for Peace”, in Ciudad Victoria, Tamaulipas, which was lead by members of political parties, journalists, and social organizations.[25] Several other marches, protesting the violence, are being planned in dozens of other cities and towns.[24] 


    Violence against Journalists

    Violence against journalists is also a major issue in Tamaulipas. According to the International Press Institute’s Death Watch, Mexico is the most dangerous country in the world this year for journalists, with 12 reporters killed in 2011.[26] The Inter American Press Association (IAPA) reported that 2011 was the most tragic year for journalists in the region in the past 20 years, with deaths in the Americas accounting for almost one third of all killed journalists in the world.[27] Many of these crimes against journalists, 98% according to the Federation of Latin American and Caribbean Journalists, are not investigated and go unpunished.[27] Drug cartels specifically target reporters and journalists in order to censor the local media. For over a decade Tamaulipas has been a “zone of silence”.[28]

    On September 23, 2011, a journalist named Maria Elizabeth Macias Castro was kidnapped and murdered. Her body was found the following day, and she had been decapitated and left in Nuevo Laredo, Tamaulipas. A note, signed with the Z that identifies the Los Zetas drug cartel, was left next to her body saying that she was killed because of her reports. Macias Castro was also a moderator and administrator of some forums in Nuevo Laredo en Vivo, a website used by citizens to report on drug cartels.[26]

    In another incident, three journalists from Tamaulipas, Arturo Moreno, Juan Carlos Alarcon, and Jorge Flores, were assaulted and illegally detained by police on September 23, 2011. In response to the violence, several Mexican journalists deactivated their accounts on social media networks to avoid future attacks.[26] 



    Corruption is another big issue in Tamaulipas. The drug cartels are able to bribe people in positions of authority in order to gain favor and influence in the area. The main forms of corruption in Tamaulipas are political corruption, corruption of prison guards, and police corruption.

    Political Corruption

    Political corruption is a major issue because it gives members of organized crime a certain degree of power over the lawmakers in the region. In Tamaulipas, there are blatant ties between local government officials and the cartels. In 2004, the federal deputy for the Worker’s Party, Juan Antonio Guajardo Anzaldua,released some photographs which showed alleged members of the Gulf Cartel collaborating with government officials. Then, in 2010, after months of documenting the links between members of the Cartel and the government, Guajardo Anzaldua found evidence to support the fact that Governor Tomas Yarrington Ruvalcaba was the "political wing" of the cartel.[29]

    Political corruption continues to be a current issue in Tamaulipas. In November 2011, former Mayor, Oscar Perez Inguanzo, was arrested by State Police in Tampico. He was charged with misuse of powers and authority, improper exercise of public functions and forgery, and misuse of public and private documents.[30]  The complaint was also filed against former Secretary Arturo Medina Fregoso, the former Mayor Fernando Altamirano Bonfire and former Treasurer Jofre Victor Mora.

    Some sources suggest that drug traffickers are able to influence the electoral process by funding some of the political campaigns. Conversely, if the politician can’t be bought, they are either killed or threatened until they comply. Some municipal seats for deputies and city council members remain vacant due to threats from cartel members.[31] These tactics essentially allow political decisions to be made by the cartels rather than the citizens of Tamaulipas. 


    Corruption of Prison Guards

    Corruption of prison guards became very apparent as an important issue in Tamaulipas in 2011 when the Mexican government stated that more than 400 inmates have been able to escape within a 15-month period due to corruption of prison authorities.[32] From January 2010 to March 2011, over 400 inmates were able to escape during 84 incidents in five different prisons run by the state authorities. In a single incident on July 15 2011, 59 prisoners escaped from the Executions and Sanctions Center in Nuevo Laredo, Tamaulipas.[33]  Seven other inmates were killed, and five prison guards disappeared during the escape.

    The Interior Ministry condemned these incidents, calling them “unacceptable”, and promised to open “a thorough investigation to bring to justice those public servants who have betrayed the public service duties.”[34] The government also announced that the Mexican Army and Federal police will increase surveillance outside of the prisons to prevent future escapes. They will also assist local law enforcement in locating and re-arresting inmates who have already escaped.[32]


    Police Corruption

    In Tamaulipas, police have the lowest salaries in the entire country. The average state police officer makes around 3,618 pesos ($250 USD) per month.[35]  These low salaries, combined with the fact that Tamaulipas is a violence-riddled border state, creates a poor environment for police officers.  A recent study from the Senate’s Public Security Committee reported that state and municipal police officers could earn up to 7,000 pesos per month (about $540 USD) by working with criminal organizations.[35] All of these factors encourage police to work with organized crime groups.

    In April 2011, 16 municipal police officers were detained by federal authorities in San Fernando, Tamaulipas. The officers allegedly provided protection to a local Los Zetas cell. The officers were also accused of covering up the mass homicides and disposal of bodies by the members of the cell.[36]

    In another incident on May 19, 2011, four law enforcement officials, including three Tamaulipas State Police officers and one group commander for the Tamaulipas State Police, were arrested by the Mexican Marines in Ciudad Victoria. The arrests took place after authorities received anonymous extortion and kidnapping complaints from civilians about the four men.[37] After taking the three police officers into custody, they pointed to their commander, Lara Castelan, as the man in charge of organizing local kidnapping and extortion schemes for the Zetas.[38] The Mexican government is taking some action to combat police corruption in the state; however, it is still very common.



    Many citizens, including shopkeepers, businessmen, and bus drivers, are extorted by the drug cartels in Tamaulipas. Many cities are operation centers for the cartels, and the local people now have to pay a fee for protection or to keep from being seen as enemies.[39] The cartels have seen decreasing revenues from trafficking as a result of interdictions by authorities, so extortion is being increasingly used in order to continue funding their operations.[40] Some of the cartels have even set up bank accounts so that businessmen can make direct deposits.[40]

    Extortion of bus drivers is also fairly common because their jobs often require them to drive through cartel-controlled territories. The cartels demand money in exchange for security and to guarantee safe travel on the roads.[41] The drivers say that they demand between 200 to 1,000 pesos ($17 to $87 USD), but there is no real guarantee the drivers will be left alone.[41]
