Loyalists opposed these changes. This led to increasing violence, riots and sectarian attacks. Paramilitary organisations became more active, including the loyalist Ulster Volunteers and the nationalist Irish Republic Army.
In trying to control the rise of violence, Northern Ireland’s police force (the Royal Ulster Constabulary) did not treat both sides equally; the treatment of the nationalists was harsher.
Pressure continued to build and in 1969 a significant riot broke out in Derry, known as ‘the Battle of the Bogside’. This is considered to be the beginning of the 'Troubles'.
