This research tries explores the major reasons of sectarian divide in early Muslim society and its expansion to the later period. It also investigates the major causes and consequences of sectarian conflict in district Jhang. The District Jhang among others faced worst nature of sectarian conflict in the history of Pakistan. The sectarianism here in Jhang is a conflict between Shiites and Deobandis. Throughout the last three decades sectarian clashes increased dramatically in Jhang. According to the office records of Jhang District Police Officer (DPO), 123 sectarian clashes were registered in various Police Stations from 1989 to 2002. These clashes produced high uncertainty among inhabitants with large-scale emigration; affected businesses; and unprecedented deaths on both sides.

Among others theological difference; religious leaders' strife and political patronage; and ethnic identities of the inhabitants are the major determinants of this conflict.
