This thesis analyzes the causes of Yasin Limpo's political family failure to maintain power through the South Sulawesi Regional Head Election 2018. This study uses Edward Gibsons Boundary Control analysis framework, as the main theory, and is equipped with elite autonomy analysis from Eva Etzony Halevy. Using qualitative methods, the results of this study show that there are three factors that led to Yasin Limpo's political family failure in the South Sulawesi regional elections in 2018. First, the weakening of political control of Yasin Limpo family caused by the failure of their boundary strengthening strategy. Secondly, there was a boundary opening strategy from challenger elites who managed to weaken Yasin Limpos political family power. Third, along with the success of the boundary opening, the intensity of competition among elites in regional election increased due to resources distribution between elites.
