The result was a victory for the Barisan Nasional (BN) at the federal level and state except state of Kelantan with opposition alliance Angkatan Perpaduan Ummah (APU) winning all 39 state assembly seats with 24 seats going to PAS and 15 for Semangat 46.^[2]

The elections marked the first after United Malays National Organisation (UMNO) party split and the subsequent constitutional crisis in 1988. The reconstituted UMNO Baru (New UMNO), led by incumbent Prime Minister Mahathir Mohamad, and the newly formed Semangat 46 (S46), led by Tengku Razaleigh Hamzah, contested for the first time in the elections.

It also marked the first time in country general election history when a credible, multi-ethnic coalition have been formed the challenge the dominance of Barisan Nasional. This also lead the country political scene from a dominant party system into two party system.^[3] The Muslim opposition parties, Pan-Malaysian Islamic Party (PAS), Semangat 46, Barisan Jemaah Islamiah Se-Malaysia (BERJASA) and Parti Hizbul Muslimin Malaysia (HAMIM) teamed up to form the Angkatan Perpaduan Ummah (APU). On the other hand, Semangat 46, Democratic Action Party (DAP) and Parti Bersatu Sabah (PBS), which withdrew from the Barisan Nasional (BN) at the eleventh hour of the general election, teamed up as Gagasan Rakyat. However, these two opposition alliances cooperated in the election but not openly due to the sensitivity of the secular DAP and the Islamic PAS working together.

At the federal level, the BN coalition under the leadership of incumbent Prime Minister Mahathir Mohamad won 127 of the 180 parliament seats to form the federal government.
