This chapter illustrates how the corrupt activities of Suharto, his cronies, and his family fueled antigovernment sentiment, even though the movement itself did not take form until after 1998. The new freedoms of Indonesia's reformasi era, combined with the backing of foreign donors, created space for the formation of new nongovernmental organizations (NGOs) with the explicit mandate to oppose corruption. As this chapter explains, these NGOs played a central role in the formation of the Commission for the Eradication of Corruption (Komisi Pemberantasan Korupsi, KPK) in 2003 and the defense of it against attacks from 2009. The movement also developed a presence at a local level, in response to the proliferation of corruption as a result of decentralization. These local movements have had mixed success, struggling with a lack of resources. Ultimately, however, the most significant obstacle the anticorruption movement faces is the lack of support from the elite level, because without it the movement remains constrained by a political system that fosters corruption.
