@401matthall@mastodon.xyz The Orange Order do marches every summer, essentially triumphalist marches which intimidate the Catholic community. The routes of those marches are contentious as they pass through Catholic areas. The Drumcree conflict over this orange lodge passing down this road was a huge flashpoint for conflict in the 1990s. What is happening now is an unwelcome revival of that. And from that point the Wikipedia article might be the best place to pick up.
