Did You Know?

TRUE. The 1991 Constitution marked a fundamental democratic transition by restoring multi-party politics after 18 years of one-party rule under UNIP. This constitutional framework reintroduced competitive elections, expanded political freedoms, and established enhanced checks on executive power. It enabled the formation of opposition parties and facilitated Zambia's first multi-party elections in nearly two decades, which resulted in a peaceful transfer of power to the Movement for Multi-Party Democracy. The constitution strengthened judicial independence and provided greater protection for fundamental human rights. This restoration of multi-party democracy represented a significant milestone in Zambia's political development and aligned the country with emerging global democratic trends in the post-Cold War era.
