The 2011–2013 protests in Sudan began in January 2011 as part of the Arab Spring regional protest movement. Unlike in other Arab countries, popular uprisings in Sudan had succeeded in toppling the government prior to the Arab Spring in 1964 and 1985. Demonstrations in Sudan however were less common throughout the summer of 2011, during which South Sudan seceded from Sudan, but resumed in force later that year and again in June 2012, shortly after the government passed its much criticized austerity plan.
