Buddhism has a long history in Indonesia, and is recognized as one of the six recognized religions in Indonesia, along with Islam, Christianity (Protestantism and Catholicism), Hinduism and Confucianism. According to the 2018 national census roughly 0.8% of the total citizens of Indonesia were Buddhists, and numbered around 2 million. Most Buddhists are concentrated in Jakarta, Riau, Riau Islands, Bangka Belitung, North Sumatra, and West Kalimantan. These totals, however, are probably inflated, as practitioners of Taoism and Chinese folk religion, which are not considered official religions of Indonesia, likely declared themselves as Buddhists on the most recent census. Today, the majority of Buddhists in Indonesia are Chinese, however small communities of native Buddhists (such as Javanese and Sasak) also exist. History Antiquity Buddhism is the second oldest religion in Indonesia after Hinduism, which arrived from India around the second century. The history of Buddhism in Indonesia is closely related to the history of Hinduism, as a number of empires influenced by Indian culture were established around the same period. The arrival of Buddhism in the Indonesian archipelago began with trading activity, from the early 1st century, by way of the maritime Silk Road between Indonesia and India. The oldest Buddhist archaeological site in Indonesia is arguably the Batujaya stupas complex in Karawang, West Java. The oldest relic in Batujaya was estimated to originate from the 2nd century, while the latest dated from the 12th century. Subsequently, significant numbers of Buddhist sites were found in Jambi, Palembang, and Riau provinces in Sumatra, as well as in Central and East Java. The Indonesian archipelago has, over the centuries, witnessed the rise and fall of powerful Buddhist empires, such as the Sailendra dynasty, the Mataram, and Srivijaya empires. According to some Chinese source, a Chinese Buddhist monk I-tsing on his pilgrim journey to India, witnessed the powerful maritime empire of Srivijaya based on Sumatra in the 7th century. The empire served as a Buddhist learning center in the region. A notable Srivijayan revered Buddhist scholar is Dharmakīrtiśrī, a Srivijayan prince of the Sailendra dynasty, born around the turn of the 7th century in Sumatra. He became a revered scholar-monk in Srivijaya and moved to India to become a teacher at the famed Nalanda University, as well as a poet. He built on and reinterpreted the work of Dignaga, the pioneer of Buddhist Logic, and was very influential among Brahman logicians as well as
