The 2018–2021 Nicaraguan protests began on 18 April 2018 when demonstrators in several cities of Nicaragua began protests against the social security reforms decreed by President Daniel Ortega that increased taxes and decreased benefits. After five days of unrest in which nearly thirty people were killed, Ortega announced the cancellation of the reforms; however, the opposition has grown through the 2013–2018 Nicaraguan protests to denounce Ortega and demand his resignation, becoming one of the largest protests in his government's history and the deadliest civil conflict since the end of the Nicaraguan Revolution. On 29 September 2018, political demonstrations were declared illegal by President Ortega. More than 2,000 protests were part of this significant mobilization.
