Modernising tradition: Reinforcing ASWAJA al-Nahdhiyah authority among millennials in Indonesia

The da'wah invitation to Islamic teachings movement of Ahl al-Sunnah wa al-Jama'ah al-Nahdhiyah , abbreviated as ASWAJA al-Nahdhiyah , formerly centred around elderly, rural, and traditional populations, has now expanded its influence to encompass the millennial demographic. The evolving landscape of time and technological advancements present novel challenges in effectively communicating the da'wah message to a generation deeply immersed in the digital era. Millennials exhibit distinct communication preferences and characteristics compared to previous generations, necessitating tailored approaches to disseminate da'wah content that resonates with their context and needs. This research aimed to achieve two primary objectives: firstly, to identify emerging forms of new traditions within the ideological reinforcement of ASWAJA al-Nahdhiyah among millennials, and secondly, to analyse the underlying factors contributing to these novel traditions within the millennial context. Employing a qualitative approach, this study utilised nethnography as its methodological framework, seeking to understand cultural experiences encompassing traces, practices, networks, and social media systems. By combining various research approaches for data collection, analysis, and interpretation, the study shed light on the reinforcement efforts that give rise to diverse new traditions. The findings highlighted that the reinforcement endeavours, including the appropriation of media platforms and the emphasis on education, cadre development, and intensive mentorship within millennial domains, significantly contribute to the acceptance and affiliation towards ASWAJA al-Nahdhiyah . Moreover, these efforts serve as a counterforce against the proliferation of radical ideologies, safeguarding the traditional religious views amid the rapid globalisation of religious understanding and transnational da'wah movements in Indonesia. Contribution: This article advanced our understanding of the evolving dynamics within the ASWAJA al-Nahdhiyah movement, particularly its adaptation to contemporary communication channels and its strategic engagement with young audiences amid the changing religious landscape in Indonesia.
