Agastya parva; the text includes puranas, and a mixture of ideas from the Samkhya and Vedanta schools of Hinduism. The Hindu-Buddhist ideas reached the peak of their influence in the 14th century. The last and largest among the Hindu-Buddhist Javanese empires, Majapahit, influenced the Indonesian archipelago. Hinduism in the colonial era Sunni Muslim traders of the Shafi'i fiqh, as well as Sufi Muslim traders from India, Oman and Yemen brought Islam to Indonesia. The earliest known mention of a small Islamic community midst the Hindus of Indonesia is credited to Marco Polo, about 1297 AD, whom he referred to as a new community of Moorish traders in Perlak. Four diverse and contentious Islamic Sultanates emerged in north Sumatra (Aceh), south Sumatra, west and central Java, and in southern Borneo (Kalimantan). These Sultanates declared Islam as their state religion and fought against each other as well as the Hindus and other non-Muslims. In some regions, Indonesian people continued their old beliefs and adopted a syncretic version of Islam. In other cases, Hindus and Buddhists left and concentrated as communities in islands that they could defend. Hindus of eastern Java, for example, moved to Bali and neighboring small islands. While this era of religious conflict and inter-Sultanate warfare was unfolding, and new power centers were attempting to consolidate regions under their control, European colonialism arrived. The Indonesian archipelago was soon dominated by the Dutch colonial empire. The Dutch colonial empire helped prevent inter-religious conflict, and it slowly began the process of excavating, understanding and preserving Indonesia's ancient Hindu-Buddhist cultural foundations, particularly in Java and western islands of Indonesia. Hinduism in the modern era After Indonesia gained its independence from Dutch colonial rule, it officially recognized only monotheistic religions under pressure from political Islam. Further, Indonesia required an individual to have a religion to gain full Indonesian citizenship rights, and officially Indonesia did not recognize Hindus. It considered Hindus as orang yang belum beragama (people without religion), and as those who must be converted. In 1952, the Indonesian Ministry of Religion declared Bali and other islands with Hindus as needing a systematic campaign of proselytization to accept Islam. The local government of Bali, shocked by this official national policy, declared itself an autonomous religious area in 1953. The Balinese government also reached out to India and former Dutch colonial officials for diplomatic and human rights support. A series of student and cultural exchange
