The article seeks to explain how Islam and the forces behind it achieved such a position since its arrival during the Malay sultanate period and until 2007. It seeks to describe the interplay of various forces, such as the Malay rulers as the head of the religion, the constitutions and various federal and state laws, the close connection between Malay and Islam, the effect of the worldwide Islamic resurgence and UMNO-PAS rivalry for political power that have directly and indirectly contributed to the proliferation of Islam in politics. Islam's early period in this area, which is currently known as West Malaysia, differs from that in the Nusantara. Muslims had arrived in the Nusantara in the fifth century due to trade activities.
