In 2005, Humala entered electoral politics, founding the Peruvian Nationalist Party (PNP) in order to run in the 2006 presidential election. Having received first place in the first round, he faced former centre-left President and APRA candidate Alan García in the second round, ultimately losing by a narrow margin. His campaign received widespread international attention in 2006 given the recent success of left-wing politicians in Latin America.[4] In 2011, he would once again run for President, and narrowly defeated Keiko Fujimori in the runoff.
Humala's election initially concerned investors, who feared he would govern similar to far-left Venezuelan PresidentHugo Chavez, a former ally of his. To assuage these fears, Humala would begin his term by choosing centrists for positions in his cabinet.[5] Humala's unpopular presidency was dominated by corruption scandals surrounding him and his politically influential wife Nadine Heredia.[6][7] Environmentalists were highly critical of Humala's mining policies, and argued that he reneged on his campaign promise to reign in mining companies.[8][9]
Humala was arrested by Peruvian authorities in July 2017 for illegally accepting bribes and awaits a corruption trial.[10]
Humala ran for president again in 2021, but lost in the first round of the election.
