[PAR] [TLE] Derry Citizens' Defence Association [SEP] The Derry Citizens' Defense Association (DCDA) was an organisation set up in Derry in July 1969 in response to a threat to nationalist residents from the Royal Ulster Constabulary (RUC) and civilian unionists, in connection with the annual parade of the Apprentice Boys of Derry on 12 August.  This followed clashes with the RUC in January and April 1969, which resulted in widespread violence.  The DCDA played a prominent role in co-ordinating the area's residents in the Battle of the Bogside, and was the effective government of the self-declared Free Derry from August to October 1969.  Its leaders included Seán Keenan, Paddy Doherty and Johnnie White.  Keenan and White were well-known republicans. [PAR] [TLE] Royal Ulster Constabulary [SEP] The Royal Ulster Constabulary was the police force in Northern Ireland from 1922 to 2001.  Following the awarding of the George Cross in 2000, its formal title became the Royal Ulster Constabulary, GC.  It was founded on 1 June 1922 as a successor to the Royal Irish Constabulary (RIC).  At its peak the force had around 8,500 officers with a further 4,500 who were members of the RUC Reserve.  During the Troubles, 319 members of the RUC were killed and almost 9,000 injured in paramilitary assassinations or attacks, mostly by the Provisional IRA, which made, by 1983, the RUC the most dangerous police force in the world in which to serve.  In the same period, the RUC killed 55 people, 28 of whom were civilians.
