When
Senegal became independent from French colonialism, a rather liberal electoral tradition was left behind that set Senegal apart from other countries gaining their independence at the time.
Leopold Senghor's
Union Progressiste Senegalaise (UPS) was positioned to facilitate a one-party hegemonic state at the moment of Senegal's independence. In 1962, a split within the UPS left the
Parti Socialiste (PS) in power; Senghor established a
plurality winner-take-all formula for national elections that effectively ensured
one-party rule in the clientelist context. While the immediate impact of this was to extend Senghor's term in power and reinforce the ruling PS, the 1978 reforms also created the first official opposition party, greatly increasing the resources available to the PDS. Early leadership of the Senegalese party-state (including Senghor) avoided the military repression that plagued other early African democracies by becoming "patrimonial democrats" and liberalizing the country without dismantling the clientelist networks that kept the ruling party in power.
Abdou Diouf succeeded Senghor as President and head of the PS in 1981. Fearing mounting opposition from the PDS, Diouf revised the constitution again in 1983, this time eliminating the maximum number of parties to be recognized on the ballot. This reform again had mixed impacts: it allowed smaller opposition parties a greater opportunity to gain control over seats in the legislature, but also precluded coordination between opposition factions, enabling a sweeping victory for Diouf's PS in elections later that year. == Coalition government reforms ==
