Stone pillars bearing inscriptions in the Pallava script, found in Kutai along the Mahakam River in East Kalimantan and dating to around the second half of the 4th century, constitute some of the oldest evidence of Hindu influence in Southeast Asia. By the 14th century, Borneo became a vassal state of Majapahit (in present-day Indonesia), later changing its allegiance to the Ming dynasty of China. The religion of Islam entered the island in the 10th century, following the arrival of Muslim traders who later converted many indigenous peoples in the coastal areas.
