Abdallah was reinstated and constructed a mercantile state by resuscitating the structures of the colonial era. His establishment of a one party state and intolerance for dissent further alienated civil society from the state. In May 1978 the Comoros were renamed the Islamic Republic of the Comoros and continued strengthening ties with the Arab world which resulted in their joining the Arab League. Abdallah's government sought to reverse Soilih's 'de-sacralization' by re-introducing the grand marriage, declaring Arabic the second official language behind French, and creating the office of the Grand Mufti. The doctorate & compromise government was dissolved, constitutional changes removed succession from a politician and neutralized the post of another possible challenger in abolishing the position of Prime Minister, which effectively cemented a client-patron network by making the civil service position dependent on Abdallah's political base. The Democratic Front's (DF) internal opposition to Abdallah was suppressed through the incarceration of over 600 people allegedly involved in a failed coup attempt. Abdallah then stocked the House of Assembly with loyal clientelist supporters through rigged parliamentary elections. All of these actions effectively consolidated Abdallah's position.
