In short: Long before modern borders, Hindu influence flowed across Southeast Asia, transforming local chieftainships into powerful empires. From the majestic temples of the Khmer to the enduring shadow puppets of Java, this ancient legacy remains woven into the region's languages, governance, and spiritual identity, surviving today as a vibrant, living tradition.

The arrival of Indic scripts and religious traditions between the 1st and 5th centuries CE marked the beginning of Southeast Asia's historical period. Indianized kingdoms emerged as local polities adopted Indian statecraft, with rulers styling themselves as Maharajas. This cultural exchange was not a one-way street; scholars suggest that early Southeast Asian groups, such as the Mon-Khmer, influenced Indian traditions, creating a shared cultural foundation. Empires like the Khmer in Indochina and the Majapahit in Java built massive hydraulic infrastructure and monumental architecture, such as Angkor Wat and Prambanan, to reflect divine rule and the Hindu caste hierarchy.

The decline of Hindu political dominance began around the 11th century as Islam and Theravada Buddhism gained prominence. However, the influence persisted. In Indonesia, Hinduism remains the major religion of Bali, and recent decades have seen a resurgence of Hindu identity among indigenous groups in Sulawesi, Sumatra, and Kalimantan. In 2007, the Indonesian Ministry of Religious Affairs estimated at least 10 million Hindus in the country. This revival is often tied to nationalist pride and the legacy of the Majapahit Empire, with communities reclaiming ancient temple sites for active worship, such as the 2019 Abhiṣeka ceremony at Prambanan, held 1,163 years after its founding.

Beyond Indonesia, Hindu traces remain deeply embedded in the region. In Cambodia and Thailand, royal coronation ceremonies still involve Hindu rituals, while Burmese culture integrates Hindu deities into its own spiritual frameworks. In Malaysia and Singapore, the migration of Tamil people during the colonial era established enduring Hindu communities that maintain traditions like Thaipusam and Deepavali. Even in the Philippines, pre-colonial linguistic and religious concepts, such as the term for karma, reveal an ancient connection to the Indian subcontinent that predates the arrival of Christianity.
