Cambodia was first influenced by Hinduism during the beginning of the Kingdom of Funan. Hinduism was one of the Khmer Empire's official religions. Angkor Wat, the largest temple complex in the world (now Buddhist) was once a Hindu temple. The main religion adhered to in Khmer kingdom was Hinduism, followed by Buddhism in popularity. Initially, the kingdom followed Hinduism as the main state religion. Vishnu and Shiva were the most revered deities worshipped in Khmer Hindu temples. Temples such as Angkor Wat are actually known as "Preah Pisnulok" ("Vara Vishnuloka" in Sanskrit) or the realm of Vishnu, to honour the posthumous King Suryavarman II as Vishnu. Hindu ceremonies and rituals performed by Brahmins (Hindu priests), typically only remained among the ruling elites of the king's family, nobles, and the ruling class .
