The previous Syrian constitution of 1973 vested the Ba'ath Party (formally the Arab Ba'ath Socialist Party) with leadership functions in the state and society and provided broad powers to the president. The president, approved by referendum for a 7-year term, was also Secretary General of the Ba'ath Party and leader of the National Progressive Front. During the 2011–2012 Syrian uprising, a new constitution was put to a referendum. Amongst other changes, it abolished the old article 8 which entrenched the power of the Ba'ath party. The new article 8 reads: "The political system of the state shall be based on the principle of political pluralism, and exercising power democratically through the ballot box". In a new article 88, it introduced presidential elections and limited the term of office for the president to seven years with a maximum of one re-election. The referendum resulted in the adoption of the new constitution, which came into force on 27 February 2012.
