 The Tela Accord required the subsequent, voluntary demobilization of the Contra guerrilla armies and the FSLN army.In 1990, a second national election installed to government a majority of non-Sandinista political parties, to whom the FSLN handed political power.Since 2006, the FSLN has returned to government, winning every legislative and presidential election in the process (2006, 2011 and 2016).
