This study aimed to understand the socio-politic situation as the source of the political behavioral change of Muhammadiyah post-new order regime and to analyze factors that contribute to that political behavioral change. This study used qualitative approach by perceiving the political behavior changes of Muhammadiyah post-new order regime through the logical inductive scheme and appropriate attention to the socio-political context situation. The result of this study shows that more transparent of political system, nonconductive condition pf socio-politics for implementation of reformation programs and doubtful role of political party condition in society politics education, and internal dynamics of Muhammadiyah which are more predominated by intellectual than Muslim Scholar are factors of political behavior friction of Muhammadiyah from accomodative-cooperative to more transparent, critic, and corrective. Meanwhile the duality of structure of Giddens does not fully comply empirical facts on the ground. The duality of structure does not disappear in case of Muhammadiyah. In other words, what has become of duality for a group might still be a duality to the other groups. In order to develop the science, is recommended for further examination about the "enforceability" concept of duality versus duality in certain communities and the factors that support the enforceability. The study also recommends a clear format and comprehensive political policy for the Muhammadiyah.
