In October 2015, South Sudan's President Salva Kiir issued a decree establishing 28 states in place of the 21 constitutionally established states. The decree established the new states largely along ethnic lines only to benefit the Dinka tribe, because they think if they have more Dinka state they will be able to easily win elections. A number of opposition parties and civil society challenged the constitutionality of this decree and Kiir later resolved to take it to parliament for approval as a constitutional amendment he made sure all who did not favor the 28 dates was fired. In November the South Sudanese parliament empowered President Kiir to create new states.
On 22 December 2014, rebel leader and former vice president Riek Machar declared the 10 states of South Sudan dissolved and the formation of 21 new states in a federal system. The declaration was not recognised by the South Sudanese government. The Sudan Tribune reported on 1 January 2015 that Machar appointed "military governors" for several of his declared states.
