Santri

The Santri are people in Javanese who practice a more orthodox version of Islam, in contrast to the more syncretic "abangan".
The American sociologist, Clifford Geertz, identified three main cultural streams ("aliran" in Indonesian) in Javanese society. Namely, the "santri", "abangan", and "priyayi". Members of the "Santri" class are more likely to be urban dwellers, and tend to be oriented to the mosque, the Qur'an, and perhaps to Islamic canon law (Sharia). In contrast, the "abangan" tend to be from village backgrounds and absorb both Hindu and Muslim elements, forming a culture of animist and folk traditions, it is also claimed that this particular class originated from Sindhi sailors, who had settled in Java. The "santri" are sometimes referred to as "Putihan" (the white ones) as distinct from the 'red' "abangan". The "priyayi" stream are the traditional bureaucratic elite and were strongly driven by hierarchical Hindu-Javanese tradition. Initially court officials in pre-colonial kingdoms, the stream moved into the colonial civil service, and then on to administrators of the modern Indonesian republic.
The "santri" played a key role in Indonesian nationalist movements, and formed the strongest opposition to President Suharto's New Order army-based administration. In contrast, the "abangan" have tended to follow the prevailing political wind; they supported Sukarno's overt nationalism, while during Suharto's subsequent presidency, they loyally voted for his Golkar party. Poorer "abangan" areas became strongholds of the Indonesian Communist Party (PKI) in stark opposition to the orthodox Muslim "santri". The cultural divisions descended into bloody conflict in 1965/66 when "santri" were opposed to communists, many of whom were from "abangan" streams. An estimated 500,000 alleged communists were killed during the transition to the New Order, and bitter political and social rivalries remain.
