The Indonesia Programme is conducting research on the role of local Islamic leaders that often ends up as influential power brokers within their localities. There is little known about when do influential clerics start gaining power and influence to become power brokers, how do power brokers form networks and alliances with the above actors, how do such networks actually work, and how do such networks exert influence on policy outcomes (e.g., Islamic regulations) at the regional and local levels. This study will identify the regional power brokers, the impetus for their regulations, and the impact of these regulations on the mainstream Muslim community and the religious minorities within the localities.
