Map of areas in Indonesia which were influenced by Islam and those which were not
The incoming of Islam and Islamic culture had affected and changed the social, economic, cultural, and political structures of Indonesian people. In the 16th century, Islam had only influenced several regions on the coasts of Sumatra, Java, part of Sulawesi and Kalimantan, and also Ternate, Tidore, and a little part of South Maluku.
This was because Islam was spread by foreign merchants and some domestic merchants by means of sailboats which could only reach coastal areas.
In the 18th century, Islam influence had reached most of Indonesia except Papua and the nearby areas, rural Kalimantan and part of south and north Sumatra. In the 20th century, Islam had influenced almost all regions in Indonesia, except Papua and rural Kalimantan where the disciples of Islam still small in number.
