Answer
Peña Nieto served as president of Mexico for six years, from 2012 to 2018. His presidency was marked by a number of significant events, including the capture and killing of drug lord Joaquín "El Chapo" Guzmán, the legalization of same-sex marriage, and the implementation of education and social welfare reforms. Despite these accomplishments, his presidency was also plagued by allegations of corruption and a high crime rate.
