<![CDATA[Ennahda is the name of one of the political parties in Tunisia which initially moved within the Islamism ideological direction. But when Ennahda elected became the head of government in 2011, the party became more compromised with political reality around and set out the rational choice while determining its political attitudes and actions. In 2015, Ennahda formed a coalition government with electoral winning parties as well as political rivals from the pro-secularist group, the Nidaa Tounes party. Some of Ennahda's loyal supporters, their party's policy is seen as a form of betrayal of his own ideological values because its acceptation for the notion of secularism and those step is considered as a deviation from Islamic beliefs. Moreover, at the 10th congress on May 20, 2016, Ennahda, which was previously seen as a symbol of the Islamism party, issued an official statement that its party separate itself between religious and political activities. Therefore, this study aims to explain the reasons and factors that led to changes in political strategy that occurred in the Ennahda party in Tunisia.

In order to support the discussion of this study, the author uses secondary data collected through library research studies and analyzed using qualitative descriptive methods.
