In October 2015, South Sudan's President Salva Kiir issued a decree establishing 28 states in place of the 10 constitutionally established states. The decree established the new states largely along ethnic lines. 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. In November the South Sudanese parliament empowered President Kiir to create new states.
