Indianisation refers to the process by which Indian culture, religion, language, and social systems spread into Southeast Asia—not through colonisation, but via the exchange of ideas, trade, and migration. This process began as early as 6000 years ago and accelerated with the rise of maritime trade between India and Southeast Asia over 2000 years ago. Indianisation was a transformative process that connected Southeast Asia to the wider world.
Indianisation profoundly shaped the history and culture of Southeast Asia. It fostered the development of complex societies, monumental architecture, and enduring religious traditions. The process was dynamic and reciprocal, with Southeast Asia also influencing India in certain respects.
Key aspects of Indianisation include:

The adoption of Hinduism and Buddhism by Southeast Asian elites and societies.
The use of Sanskrit as a language of culture, law, and religion.

The introduction of Indian architectural styles, temple complexes, and urban planning. For example, more than 200 temples were constructed across a vast 420 square kilometre area to form the Angkor Archaeological Park in today's Cambodia, with Angkor Wat and Angkor Thom standing out as the principal complexes, both predominantly built from sandstone.
The spread of Indian legal systems, literature, and cosmological concepts.
Indianisation was not a one-way imposition; Southeast Asian societies selectively integrated Indian elements with their own traditions, creating unique local cultures.
Indian maritime influence in Southeast Asia was profound and multifaceted. It was not limited to trade but encompassed the transmission of religion, language, architecture, governance, and technology. The maritime networks established by Indian traders and sailors served as the backbone for these exchanges, shaping the development of Southeast Asian societies and leaving a legacy that is still visible today in the region’s temples, languages, and traditions of countries like Cambodia, Indonesia, Vietnam, and Thailand.

The process of Indianisation enhanced the maritime skills and technological abilities of Southeast Asian communities, empowering them to undertake extended oceanic journeys that eventually led to the settlement of New Zealand’s first settlers.
