1960, in a smooth transition, Togo severed its constitutional ties with France, shed its UN trusteeship status, and became fully independent under a provisional constitution with Olympio as president. Independence and turmoil A new constitution adopted by referendum in 1961 established an executive president, elected for 7 years by universal suffrage and a weak National Assembly. The president was empowered to appoint ministers and dissolve the assembly, holding a monopoly of executive power. In elections that year, from which Grunitzky's party was disqualified, Olympio's party won 100% of the vote and all 51 National Assembly seats, and he became Togo's first elected president. During this period, four principal political parties existed in Togo: the leftist Juvento, the Democratic Union of the Togolese People (UDPT), the PTP, founded by Grunitzky but having limited support, and the Party of Togolese Unity, the party of President Olympio. Rivalries between elements of these parties had begun as early as the 1940s, and they came to a head with Olympio dissolving the opposition parties in January 1962 because of alleged plots against the majority party government. The reign of Olympio was marked by the terror of his militia, the Ablode Sodjas. Many opposition members, including Grunitzky and Meatchi, were jailed or fled to avoid arrest. On 13 January 1963 Olympio was overthrown and killed in a coup d'état led by army non-commissioned officers dissatisfied with conditions following their discharge from the French army. Grunitzky returned from exile 2 days later to head a provisional government with the title of prime minister. On 5 May 1963, the Togolese adopted a new constitution by referendum, which reinstated a multi-party system. They also voted in a general election to choose deputies from all political parties for the National Assembly, and elected Grunitzky as president and Antoine Meatchi as vice president. Nine days later, President Grunitzky formed a government in which all parties were represented. During the next several years, the Grunitzky government's power became insecure. On 21 November 1966, an attempt to overthrow Grunitzky, inspired principally by civilian political opponents in the UT party, was unsuccessful. Grunitzky then tried to lessen his reliance on the army, but on 13 January 1967, a coup led by Lt. Col. Étienne Eyadéma (later Gen. Gnassingbé Eyadéma) and Kléber Dadjo ousted President Grunitzky without bloodshed. Following the coup, political parties were banned, and all constitutional processes were suspended. Dadjo became the chairman
