Organisers of Saturday's loyalist "Love Ulster" march and rally in the Shankill area of Belfast are planning further events across Northern Ireland.
Up to 5,000 Orange bandsmen and ordinary unionists marched up the Shankill Road for a rally in Woodvale Park. Speakers, including victims campaigner William Frazer, called for the British government to take seriously the concerns of Protestants concerning the peace process.
The march assembled in the lower Shankill area before leaving for Woodvale.
There was no official party-political representation and the parade was led by relatives of those who died at the hands of the IRA throughout the Troubles.
Jim Dixon, a survivor of the Enniskillen Poppy Day bombing, was in the leading group.
The march took about 30 minutes to pass the site of the former Frizzell's fish shop, bombed by the IRA in 1993, where nine Protestants and one of the bombers died.
The second bomber, Seán Kelly, was released from prison under the terms of the Belfast Agreement, rearrested on the orders of Northern Secretary Peter Hain and then dramatically freed again in the run-up to the IRA declaration last July that its campaign was over.
Those who addressed the Woodvale Park rally denounced the handling of the Kelly case as one of a series of "concessions" to republicans aimed to buy their participation in the political process.
They claimed that such measures only served to deny Protestants their rights and to elevate republican concerns above those of ordinary unionists.
Speakers - who included leading Belfast loyalist John McVicar, Mr Frazer, Belfast Orange leader Dawson Baillie, the Rev Mervyn Gibson and loyalist women's campaigner Jean Barnes - declared they had stood up to the IRA and would not be ignored by the Northern Ireland Office.
The platform speeches denounced, among others, British prime minister Tony Blair, Taoiseach Bertie Ahern, Chief Constable Sir Hugh Orde, the Parades Commission, Fr Alec Reid, the Catholic Church, the media and particularly the BBC.
All speakers concluded with "No Surrender".
Mr Hain came in for sustained criticism, especially over Kelly's release and the decision to scrap the home battalions of the Royal Irish Regiment. Posters carried by marchers proclaimed "PSNI - Peter Hain's Stormtroopers", while others said "PSNI - Proactively Supporting Nationalist Ideology".
The Rev Gibson, in a particularly well-received address, asked the crowd: "Why does the Union not feel secure? Why do visionaries, as Peter Hain referred to the IRA leadership, be indulged? Why do organisations like Love Ulster come into existence? Because the unionist, loyalist people are not being listened to.
"Our elected leaders are treated like some remnants of a difficult colonial outpost. Plant a memorial tree here - hand out some 'gongs' there - keep the natives happy. I suspect if they handed out coloured beads they would not even have the sense to make them Orange."
