a threat to the ruling houses across the country. Margai appointed many non-Creoles to the country's civil service in Freetown, in an overall diversification of the civil service in the capital, which had been dominated by members of the Creole ethnic group. As a result, Albert Margai became unpopular in the Creole community, many of whom had supported Sir Milton. Margai was accused of favouring members of his own Mende ethnic group for prominent positions. In 1967, riots broke out in Freetown against Margai's policies; in response he declared a state of emergency across the country. Sir Albert was accused of corruption and of a policy of affirmative action in favour of his own Mende ethnic group. Sir Albert Margai took power and sought to make the army homogeneously Mende. He also endeavoured to change Sierra Leone from a democracy to a one-party state.

Steven was later freed and fled the country; went into exile in neighbouring Guinea.

They seized control of the government, arresting Lansana, and suspending the constitution. The group set up the National Reformation Council (NRC), with Andrew Juxon-Smith as its chairman and Head of State of the country. On 18 April 1968 a group of low ranking soldiers in the Sierra Leone Army who called themselves the Anti-Corruption Revolutionary Movement (ACRM), led by Brigadier General John Amadu Bangura, overthrew the NRC junta. The ACRM junta arrested many senior NRC members. They reinstated the constitution and
