Islam and Java
Islam spread into Java and moved on to the Celebes
and Mindanao in the Philippines.
Coastal cities were the most receptive to Islam.
Their conversion linked them to a Muslim system
connected to the principal Indian Ocean ports.
Buddhist dynasties were present in many regions, but
since Buddhist conversions were limited to the elite, the
mass of the population was open to the massage of
Sufis.
The island of Bali and mainland Southeast Asia, where
Buddhism had gained popular support, remained
impervious to Islam.
