Lebanon is a parliamentary democracy that includes confessionalism, in which high-ranking offices are reserved for members of specific religious groups. The President, for example, has to be a Maronite Christian, the Prime Minister a Sunni Muslim, the Speaker of the Parliament a Shi’a Muslim, the Deputy Prime Minister and the Deputy Speaker of Parliament Eastern Orthodox. This system is intended to deter sectarian conflict and to represent fairly the demographic distribution of the 18 recognized religious groups in government.
