After President Omar Bongo was re-elected in 1993, in a disputed election where only 51% of votes were cast, social and political disturbances led to the 1994 Paris Conference and Accords. These provided a framework for the next elections. Local and legislative elections were delayed until 1996–97. In 1997, constitutional amendments put forward years earlier were adopted to create the Senate and the position of vice president, as well as to extend the president's term to seven years.
