Indonesia is a republic with a presidential system. Following the fall of the New Order in 1998, political and governmental structures have undergone sweeping reforms, with four constitutional amendments revamping the executive, legislative and judicial branches. Chief among them is the delegation of power and authority to various regional entities while remaining a unitary state. The President of Indonesia is the head of state and head of government, commander-in-chief of the Indonesian National Armed Forces (''Tentara Nasional Indonesia'', TNI), and the director of domestic governance, policy-making, and foreign affairs. The president may serve a maximum of two consecutive five-year terms.
