Celtic and Rangers, the two clubs that make up the so-called Glasgow "Old Firm", is one of the fiercest, and most complex, rivalries in world football.
Since their first meeting in the 1880s, the two sides have gathered local followings based on religion, race and class. As one follower told Al Jazeera, the rivarly represents "politics, identity and ignorance".
In recent years, the competition has taken on dark undertones, such as sectarian chants and violence between supporters. Now, the two teams are set to play each other again for the first time this season, and 396th time overall, on Sunday.
