THE GAA will mark the centenary of 'Gaelic Sunday' this weekend.
Events are expected to be held across Ireland to remember what is regarded as one of the most significant days in the association's history.
At the time Ireland was in the grip of political turmoil and attempts by the British to introduce conscription were being resisted.
The GAA was being blamed in part for the opposition.
The association said the issue reached crisis point in July 1918 when an Ulster championship match was prevented from taking place by crown forces in Cootehill, Co Cavan.
A ban was then put on place on gatherings without prior written permission from the RIC, effectively outlawing matches.
In response, the GAA sought to make the order unenforceable by arranging a match in every parish in Ireland to take place at 3pm on August 4 1918.
It is estimated that 54,000 players took part in games and more than 100,000 spectators turned out.
The day passed off without major incident and the British dropped their demands.
The GAA will remember the act of defiance this Sunday at Croke Park, when Dublin and Roscommon meet in a 'Super 8' foobtall clash and the Under 20 All-Ireland final is played between Kildare and Mayo.
Between the matches 32 boys and girls - one from each county - will wear their club colours as they march behind the Artane Band.
The children will also meet GAA president John Horan.
Ulster clubs represented at the parade will be Lamh Dhearg (Antrim), Kilcoo (Down), Omagh St Enda's (Tyrone), Derrygonnelly Harps (Fermanagh), Armagh Harps, Slaughtneil (Derry), Cavan Gaels, Kilcar (Donegal) and Scotstown (Monaghan).
