The existence of Islam in Balige City can survive so far so that it has experienced developments such as the increasing number of worshippers. This will require improving the facilities of houses of worship for Muslims in worship. The government of the Ministry of Religious Affairs of Balige City tried to overcome this by facilitating the establishment of mosques and arranging the certification of the status of the land to avoid land disputes. Similarly, the views of the majority community towards minority communities are still relatively good. However, there are still obstacles found in interacting such as there are still some minority communities who have not been able to socialize. So they hope that minorities can blend into the majority society with each other. The conclusion of the study is that Islam can maintain its existence and is well accepted in Balige City. However, limitations as a minority community does not close will cause its slowness in developing. Such as facilities for houses of worship that have not been fulfilled adequately and so on.
