The major civil society group that campaigned against military rule prior to the advent of the fourth republic in Nigeria is the Campaign for Democracy. This group was formed in 1992 and was made up of several activists and pro-democracy advocates who were committed to fighting for democracy and human rights in Nigeria. The Campaign for Democracy organized peaceful protests and demonstrations against military rule, and also engaged in advocacy and lobbying activities to put pressure on the government to transition to civilian rule. They were instrumental in pushing for the annulment of the 1993 presidential election, which is widely considered to be the freest and fairest election in Nigeria's history. Overall, the Campaign for Democracy played a significant role in the struggle for democracy in Nigeria and helped to pave the way for the eventual transition to civilian rule in 1999.
