Atlacomulco is a city and municipality located in the northwest of the State of Mexico in central Mexico, 63 km from the state capital of Toluca. The name is derived from the Nahuatl phrase "atlacomulli" which means "where there are wells." The city, with a population of 20,477 is surrounded by rural area in which 75% of the rest of the municipality lives. The municipality has a sizable percentage of indigenous language speakers, mostly Mazahua. The Mazahua name for the area is Embaró, which means "colored rock." Agriculture is still the main economic activity, but the development of a number of industrial parks, such as Atlacomulco 2000, which allowed the seat to reach city statues by 1987. Atlacomulco is also the origin of a political group called "Grupo Atlacomulco" made up of powerful political figures, who do not affirm that it exists.

The area was originally settled by the Mazahuas but the date of their arrival is not known. This area eventually came under the control of Azcapotzalco during the reign of Tezozomoc, calling it the province of Mazahuacan. Later, it came under the control of Tlacopan or Tacuba. After the Spanish conquest of the Aztec Empire, Atlacomulco became the encomendero of Francisco de Villegas in 1535. In 1537, the regent of Ixtlahuaca took possession of the area, and relocated Spanish families here to settle. The municipality remained quiet through the rest of the colonial period and during the various wars of the 19th century. The only events of note were the passing of the armies of Miguel Hidalgo and Ignacio López Rayón on the edges of the municipality during the Mexican War of Independence.

Enrique Peña Nieto (born July 20, 1966) is a Mexican politician. A member of the Institutional Revolutionary Party (Partido Revolucionario Institucional, PRI), he served as governor of the State of Mexico from 2005 to 2011. On September 19, 2011, he announced his candidacy in the 2012 Mexican presidential election to succeed Felipe Calderón, and formally registered his candidacy on November 27, 2011.

Peña Nieto was born at Atlacomulco in Mexico State. His father, Gilberto Enrique Peña del Mazo, worked for the Comisión Federal de Electricidad and his mother, María del Perpetuo Socorro Ofelia Nieto Sánchez, was a school teacher. Peña is related to several politicians: Severiano Peña, mayor of Acambay in 1914, 1916, 1921 and 1923; Alfredo del Mazo González, former governor; and Arturo Montiel Rojas, also former governor. In 1993, Peña married his first wife Mónica Pretelini with whom he had three children: Paulina, Alejandro and Nicole. Pretelini died on January 11, 2007 due to an epileptic episode. In 2008, Peña Nieto announced publicly in a TV show his romantic relationship with Televisa soap opera actress Angélica Rivera. Rivera and Peña Nieto married on November 27, 2010 in Toluca.

Enrique Peña Sánchez (Puerto Padre, Las Tunas Province, 17 July 1880 – Havana, 13 April 1922) was a leading Cuban cornet player, orchestra leader and composer.

Born in a small town in the old province of Oriente, Peña studied with Marcos González and José Santos Betancourt. In 1902 he moved to Havana, and founded the band La Juventud, with himself as director and cornet, Rogelio Solis (double bass), Félix González (figle), José Belén Puig (first clarinet), José Urfé (second clarinet), José de los Reyes (kettle drum) and Rufino Cárdenas (güiro). This band had several members who became well known; Puig went on to become a famous leader of his own charanga. The band functioned until 1906.

His second band was called the Orquesta típica de Enrique Peña. Its line-up was Peña (cornet); Antonio González (trombone); Féliz González (figle); José Belén Puig (1st clarinet); José Urfé (2nd clarinet); Julián Barreto (violin); Alfredo Sáenz (violin); José de los Reyes (tympani); Rufino Cárdenas (güíro) and unknown (double bass). This orchestra became famous for being the first to play El bombín de Barreto (Barreto's bowler hat), written by Urfé, which was supposedly the first danzón to incorporate a syncopated third part, influenced by the son. The group recorded about 150 numbers, some of which are available on CD.
