General elections had been planned for January 2010 but were postponed due to the earthquake. Elections were held on 28 November 2010 for the senate, the parliament and the first round of the presidential elections. The run-off between Michel Martelly and Mirlande Manigat took place on 20 March 2011, and preliminary results, released on 4 April, named Michel Martelly the winner. In 2011 both former dictator Jean-Claude Duvalier and Jean-Bertrand Aristide returned to Haiti; attempts to try Duvalier for crimes committed under his rule were shelved following his death in 2014. In 2013, Haiti called for European nations to pay reparations for slavery and establish an official commission for the settlement of past wrongdoings. Meanwhile, after continuing political wrangling with the opposition and allegations of electoral fraud, Martelly agreed to step down in 2016 without a successor in place. An interim president, Jocelerme Privert, then took office. After numerous postponements, partly owing to the effects of devastating Hurricane Matthew, elections were eventually held in November 2016. The victor, Jovenel Moïse of the Haitian Tèt Kale Party, was subsequently sworn in as president in 2017. The 2018–2021 Haitian protests are demonstrations in cities throughout Haiti that began on 7 July 2018, in response to increased fuel prices. Over time these protests evolved into demands for the resignation of president Moïse.
