The game of hurling has been played in Dublin long since before the foundation of the Dublin Senior Hurling Championship and the GAA. According to Irish historian James Ware (1594-1666), it was customary in the 13th century for the inhabitants of Dublin to organise hurling matches on festive days. On Easter Monday 1209, hundreds of Dublin citizens left the safety of the city walls and descended on the woods near Cullenswood, now Ranelagh, for a hurling match. Tragically, the hurlers and spectators were ambushed by rival clans who had come down from the Wicklow Mountains. Over three hundred Dubliners (including women and children) were slaughtered in the 1209 Cullenswood massacre. This day was commemorated by the citizens of Dublin for many centuries afterwards and became known as Black Monday.
