The Central African Republic is a republic with a transitional government of national unity. The president and prime minister share executive power. The legislative and judicial branches are weak. The last general election occurred in 2011. Citizens reelected President Francois Bozize in what national and international observers considered a flawed election. On January 11, the Economic Community of Central African States (ECCAS) brokered the Libreville Accords, which provided for transitional and power sharing measures among President Bozize, the political opposition, and the Seleka rebel alliance, which had launched an insurgency in December 2012. Within weeks of the Libreville Accords, Seleka leader Michel Djotodia accused President Bozize of ignoring the agreement, advanced on the capital, and deposed Bozize on March 24. Djotodia proclaimed himself president, suspended the constitution, dissolved the previous government, and began to rule by decree. On April 18, ECCAS adopted the Ndjamena Declaration, which provided for the establishment of a transitional government leading to elections in 18 months after the swearing-in of the transitional president. Djotodia was sworn in as transitional president on August 18 under the terms of the transitional charter, which took effect the same day. State rule, already weak under Bozize, largely collapsed during the year. The absence of civilian administration, defense, and police forces led to a security vacuum that resulted in lawlessness in Bangui and throughout the country. On September 11, Djotodia formally dissolved the Seleka alliance. Nevertheless, former Seleka members continued to engage in conflict with armed militia groups throughout the country, including with a group called the Young Patriots established in the final days of the Bozize regime to counter the Seleka and their supporters. Armed groups who opposed the Seleka, including the Young Patriots, came to be known collectively as the anti-Balaka. Sectarian violence resulted in an estimated 500 deaths between December 5-7 and an estimated 200 deaths from December 20-26. While the violence was most pronounced in Bangui, it was also concentrated in Ouham prefecture, a region with ties to former president Bozize. Authorities under both Bozize and Djotodia failed to maintain effective control over the security forces. Security forces committed extensive human rights abuses.
