Sectarian groups are communities that are divided based on specific religious, ethnic, or ideological beliefs. These groups often form around shared identities, leading to a strong sense of belonging among their members. Sectarianism can arise from historical conflicts, differing interpretations of faith, or cultural distinctions, which can sometimes lead to tension or violence between groups. In many regions, sectarian groups can influence politics, social dynamics, and community relations. For example, in the Middle East, sectarian divisions between Sunni and Shia Muslims have shaped political landscapes and conflicts. Understanding these groups is essential for addressing issues of peace and coexistence in diverse societies.
