Islam did not develop through political expansion or military conquest, but rather through a peaceful approach that emphasized cultural dialogue and social value transformation. This study analyzes the da'wah strategies of the Walisongo on the island of Java through an approach of acculturation of local arts and culture. The study uses a descriptive qualitative method with a literature review and historical analysis approach. The results of the study show that Walisongo utilized performing arts, mosque architecture, and social traditions as media for da'wah to convey Islamic values persuasively and contextually. This acculturative approach enabled the process of Islamization to take place peacefully without causing social conflict and strengthened the acceptance of Islam within the cultural structure of Javanese society. These findings confirm that da'wah based on local wisdom is an effective model for building a moderate, inclusive, and sustainable Islam.
