Ratsiraka's dwindling popularity in the late 1980s reached a critical point in 1991 when presidential guards opened fire on unarmed protesters during a rally. Within two months, a transitional government had been established under the leadership of Albert Zafy (1993–96), who went on to win the 1992 presidential elections and inaugurate the Third Republic (1992-2010). The new Madagascar constitution established a multi-party democracy and a separation of powers that placed significant control in the hands of the National Assembly. The new constitution also emphasized human rights, social and political freedoms, and free trade. Zafy's term, however, was marred by economic decline, allegations of corruption, and his introduction of legislation to give himself greater powers. He was consequently impeached in 1996, and an interim president, Norbert Ratsirahonana, was appointed for the three months prior to the next presidential election. Ratsiraka was then voted back into power on a platform of decentralization and economic reforms for a second term which lasted from 1996 to 2001.
