Following the upheavals in 1965–66, religious identification of citizens became compulsory, and there has been a renaissance of Buddhism and Hinduism since then. As one has to choose a religion out of the five official religions in Indonesia; i.e. Islam, Protestantism, Catholicism, Hinduism, and Buddhism, the latter two became alternatives for people who did not want to be Muslims or Christians. Confucianism is also common among Chinese Indonesians. In the post-Suharto era, it is recognised as an official religion along with the aforementioned five.
