In Indonesia, "land mafias" (mafia tanah) proliferate, alongside mafias that cluster around other commodities and state functions. We analyze the composition, character, modes, and sources of resilience of Indonesian land mafias, noting similarities with formations elsewhere, especially India. While taking care to avoid reifying the category, we view land mafias as opportunistic networks, or assemblages, of diverse actors including land brokers, investors, lawyers, gangsters, bureaucrats, law enforcement officers, and politicians. Their goal is to harvest rents from the transfer of ownership and control over land. They feature two elements: first, reliance on coercion (not always physical violence but always entailing transfer of property without freely-given consent, often via fraud or manipulation); second, institutional amorphousness crossing the state-society boundary. We analyze four modes of land mafia operation, though their nebulousness defies easy categorization. In explaining land mafia resilience, we acknowledge Indonesia's property boom as a driver, but note that the ubiquity of mafias points to a more fundamental explanation: a variety of state formation involving pervasive engagement by state actors in illegal behavior in collusion with wealthy private actors. Mafias are central to Indonesian state formation, rather than aberrations. Feedback loops that incentivize illegal behavior make land mafias difficult to eradicate.
