Established in the Constitution of 1993, the President of Peru, officially the President of the Republic (Presidente de la República), is the head of state of Peru and represents the republic in official international matters. The presidential term is five years. Also, Peru allows an incumbent President to succeed himself only once. Therefore, after a re-election (ten years in power) an incumbent president is barred from running in the election. (A former president may run again in subsequent presidential elections if he hasn't been in power twice). The current president of Peru is Ollanta Humala, elected in 2011.

The change of government takes place on July 28, which is the date of independence from Spain and thus a national holiday.

During its more than 180 years of independence, Peru has been ruled by the military leaders who fought for independence, the leaders of the War of the Pacific, representatives of the aristocracy, and democratically-elected leaders. Also, the history of the presidency has involved civil wars, coups and violence. More than once, several individuals claimed the right to be president at the same time.

Peru ⁱ/pəˈruː/ (Spanish: Perú; Quechua: Perú;Aymara: Piruw), officially the Republic of Peru (Spanish: República del Perú, pronounced: [reˈpuβlika ðel peˈɾu] ( listen)), is a country in western South America. It is bordered on the north by Ecuador and Colombia, on the east by Brazil, on the southeast by Bolivia, on the south by Chile, and on the west by the Pacific Ocean.

Peruvian territory was home to ancient cultures, spanning from the Norte Chico civilization, one of the oldest in the world, to the Inca Empire, the largest state in Pre-Columbian America. The Spanish Empire conquered the region in the 16th century and established a Viceroyalty, which included most of its South American colonies. After achieving independence in 1821, Peru has undergone periods of political unrest and fiscal crisis as well as periods of stability and economic upswing.

Peru is a representative democratic republic divided into 25 regions. Its geography varies from the arid plains of the Pacific coast to the peaks of the Andes Mountains and the tropical forests of the Amazon Basin. It is a developing country with a high Human Development Index score and a poverty level around 31%. Its main economic activities include agriculture, fishing, mining, and manufacturing of products such as textiles.

Ollanta Moisés Humala Tasso (Spanish pronunciation: [oˈʎanta mojˈses uˈmala ˈtaso]) (born June 27, 1962) is a Peruvian politician and the President of Peru. Humala, who previously served as an army officer, lost the presidential election in 2006 but won the 2011 presidential election in a run-off vote. He was elected as President of Peru in the second round, defeating Keiko Fujimori.

The son of Isaac Humala, a labour lawyer, Humala entered the Peruvian Army in 1982. In the military he achieved the rank of Lieutenant Colonel; in 1992 he fought in the internal conflict against the Shining Path and three years later he participated in the Cenepa War against Ecuador. In October 2000, Humala led an unsuccessful military revolt by 39 soldiers in the southern city of Tacna against President Alberto Fujimori; he was pardoned by the Peruvian Congress after the downfall of the Fujimori regime.

In 2005 he founded the Peruvian Nationalist Party and registered to run in the 2006 presidential election. The nomination was made under the Union for Peru ticket as the Nationalist party did not achieve its electoral inscription on time. He passed the first round of the elections, held on April 9, 2006, with 30.62% of the valid votes. A runoff was held on June 4 between Humala and Alan García of the Peruvian Aprista Party. Humala lost this round with 47.47% of the valid votes versus 52.62% for García. After his defeat, Humala remained as an important figure within Peruvian politics.

Fernando Belaúnde Terry (October 7, 1912 – June 4, 2002) was President of Peru for two non-consecutive terms (1963–1968 and 1980–1985). Deposed by a military coup in 1968, he was re-elected in 1980 after eleven years of military rule. He was recognized for his personal integrity and his commitment to the democratic process.

The second of four children, Belaúnde was born in Lima into an upper-class family of Spanish forebears. His father, Rafael Belaúnde Diez Canseco, a teacher, served as President of the Council of Ministers; his grandfather was a finance minister; and one of his great-grandfathers was a President of the Republic.

During the dictatorship of Augusto B. Leguía, the persecution for the political activities of his father Rafael and his uncle Víctor Andrés Belaúnde prompted the family to move to France in 1924, where Fernando attended high school and received his initial University education in engineering.

From 1930 to 1935, Belaúnde studied architecture in the United States, where he first attended the University of Miami (where his father was also teaching), and in 1935 transferred to the University of Texas at Austin, where he obtained his degree as an architect. He later moved to Mexico and worked as an architect for a brief time, but returned to Peru in 1936 and started his professional career as an architect designing private homes. In 1937, he started a magazine called El Arquitecto Peruano ("Peruvian Architect"), which dealt with interior design, general urbanism and housing problems the country was facing. This also gave way to the Architects Association of Peru and the Urbanism Institute of Peru.

Barack Hussein Obama II (ⁱ/bəˈrɑːk huːˈseɪn oʊˈbɑːmə/; born August 4, 1961) is the 44th and current President of the United States. He is the first African American to hold the office. In January 2005, Obama was sworn in as a U.S. Senator in the state of Illinois. He would hold this office until November 2008, when he resigned following his victory in the 2008 presidential election.

Born in Honolulu, Hawaii, Obama is a graduate of Columbia University and Harvard Law School, where he was the president of the Harvard Law Review. He was a community organizer in Chicago before earning his law degree. He worked as a civil rights attorney in Chicago and taught constitutional law at the University of Chicago Law School from 1992 to 2004. He served three terms representing the 13th District in the Illinois Senate from 1997 to 2004.

Following an unsuccessful bid against the Democratic incumbent for a seat in the United States House of Representatives in 2000, Obama ran for the United States Senate in 2004. Several events brought him to national attention during the campaign, including his victory in the March 2004 Illinois Democratic primary for the Senate election and his keynote address at the Democratic National Convention in July 2004. He won election to the U.S. Senate in Illinois in November 2004. His presidential campaign began in February 2007, and after a close campaign in the 2008 Democratic Party presidential primaries against Hillary Rodham Clinton, he won his party's nomination. In the 2008 presidential election, he defeated Republican nominee John McCain, and was inaugurated as president on January 20, 2009. Nine months later, Obama was named the 2009 Nobel Peace Prize laureate. In April 2011, he announced that he would be running for re-election in 2012.
