Kirchnerism (Spanish: kirchnerismo) is an Argentinian political group formed by the supporters of the late Néstor Kirchner, president of Argentina from 2003 to 2007, and of his wife Cristina Fernández de Kirchner, president from 2007 until 2015. Although the Kirchners are members of the Justicialist Party (the original, official and largest Peronist party, founded by Juan Perón in 1947), Peronism itself is a broad movement, and many Peronists oppose them ("Anti-Kirchnerist Peronism").
