Belfast City Hall flag protests

On 3 December 2012, Belfast City Council voted to limit the days that the Union Flag (the flag of the United Kingdom) flies from Belfast City Hall. Since 1906, the flag had been flown every day of the year. This was reduced to 18 specific days a year, the minimum requirement for UK government buildings. The move to limit the number of days was backed by the council's Irish nationalists while the Alliance Party abstained from the vote; it was opposed by the unionist councillors.

As a response, Ulster loyalists and British nationalists held street protests throughout Northern Ireland. They saw the council's decision as part of a wider 'cultural war' against 'Britishness' in Northern Ireland. On the night of the vote, protesters tried to storm City Hall. Throughout December and January, protests were held almost daily and most involved the protesters blocking roads while carrying Union Flags and banners. Some of these protests led to clashes between loyalists and the police, sparking riots. Rioters attacked police with petrol bombs, bricks, stones and fireworks; police responded with plastic bullets and water cannon. Alliance Party offices and the homes of Alliance Party members were attacked, while Belfast City Councillors were sent death threats. According to police, some of the violence was orchestrated by high-ranking members of the Ulster Volunteer Force (UVF) and Ulster Defence Association (UDA). Loyalists also put up thousands of Union flags in public places, which further heightened tension.

After February 2013, the protests have been smaller and less frequent, and have led to greater loyalist protests about related issues, such as restrictions on traditional loyalist marches.
