Islam and the Shaping of Urban Multiculturalism in Pematangsiantar: A Social History Perspective

Abstract

Pematangsiantar offers an important case for understanding urban Islam in a religiously plural city. Muslims constitute 45.83% of the population, while Protestants and Catholics together account for 50.03%, making Islam a large but not demographically dominant religious community. This article examines how Islam has been historically articulated, socially institutionalised, and culturally negotiated in Pematangsiantar’s multicultural urban life. Using a social history approach, the study combines documentary analysis of official demographic data, published local histories, and peer-reviewed studies on Islam, mosques, pluralism, and local wisdom. The findings show that Islam in Pematangsiantar developed through commercial networks, royal patronage, mosque-centered institution building, da’wah organisations, and everyday encounters across religious communities. The article argues that urban Islam in Pematangsiantar is best understood as a negotiated, civic, and culturally embedded religiosity, rather than merely as a demographic presence.
