Parades are a prominent cultural feature of Northern Ireland. The overwhelming majority of parades are held by Ulster Protestant, unionist or Ulster loyalist groups, but some Irish nationalist, republican and non-political groups also parade. Due to longstanding controversy surrounding the contentious nature of some parades, a quasi-judicial public body — the Parades Commission — exists to place conditions and settle disputes. Although not all parading groups recognise the Commission's authority, its decisions are legally binding.
The majority of parades in Northern Ireland (nearly 70% in 2003/4) are organised by Protestant and/or unionist groups, leading some people to view attempts to restrict parades as an attack on Protestant and/or unionist culture. Parades typically take place on Saturdays, which means that participants and spectators do not have to take time off work, and avoid parading on Sunday, which some Protestants believe should only be spent on purely religious activities. The only exceptions to this are the Twelfth of July parades, which are held on the same date each year, (unless the 12th falls on a Sunday, in which case it is postponed to Monday the 13th), and church parades, which are held on Sunday.
Orange walk
The Orange Institution holds hundreds of parades throughout Northern Ireland every year. The biggest of these are usually on the twelfth of July ('The Twelfth'), in commemoration of the Battle of the Boyne. Individual lodges also parade at various times of the year, particularly leading up to the Twelfth. Parades in memory of the dead of World War I, particularly the 36th (Ulster) Division at the Battle of the Somme, are held in July and November. Junior lodges from Armagh, South Tyrone and Fermanagh parade annually at the end of May. On the last Saturday in October, Reformation Day is celebrated with the year's last major Orange parades. In Belfast, these proceed to Saint Anne's Cathedral for a church service.
The Apprentice Boys of Derry exist in commemoration of the siege of Derry in the seventeenth century.
