The Holy Cross dispute occurred in 2001 and 2002 in the Ardoyne area of north Belfast, Northern Ireland. During the 30-year conflict known as the Troubles, Ardoyne had become segregated – Ulster Protestants and Irish Catholics lived in separate areas. This left Holy Cross, a Catholic primary school for girls, in the middle of a Protestant area. In June 2001—during the last week of school before the summer break—Protestant loyalists began picketing the school, claiming that Catholics were regularly attacking their homes and denying them access to facilities.
