This paper explores how Hezbollah in Lebanon constructs its identity, narrative of sacrifice, and political legitimacy through political theory and digital media. By starting from Nationalism and Pan-Arabism, the first chapter analyzes how Hezbollah responds to the historical marginalization of Shia, using the language of "resistance" to establish an identity framework and combines critical theory to reveal the dual role of its discourse in mobilization and control. The second chapter focuses on Hezbollah's official website Moqawama.org, using media and symbolic analysis methods to analyze how it constructs a "resistance culture" through "martyr" narratives, images, and religious language to strengthen its legitimacy in Lebanon and the region. The paper points out that Hezbollah's legitimacy does not come from the state system, but it is obtained through continuous narrative shaping and symbolic practice. Against the consequences of weak state governance and ongoing regional conflicts, its model provides a new perspective for understanding political mobilization and ideological reshaping in the contemporary Arab World.
