 On 27 August 1968, DHAC organised another protest in the Guildhall's council chamber.Immediately afterwards Eamonn Melaugh telephoned the Northern Ireland Civil Rights Association (NICRA) and invited them to organise a march in Derry.Together with NICRA, they organised the 5 October 1968 civil rights demonstration in Derry, whose banning and violent suppression by the Royal Ulster Constabulary (RUC) was one of the catalysts of the so-called 'Troubles'.
