In the late 1960s periods of violence began in Ireland that have often been called the Troubles. The protestant police attacked Catholics during marches for civil rights. And as the troubles continued, troops were sent from Britain and militant groups from Northern Ireland to keep law and order.
The Catholics had a revolutionary way of fighting back, like: marches, bombing of Protestant areas and hunger strikes in prisons, many of these prisoners were sent to prison without a trial. All this was to lead to 30 years of terror, killings bombings. In total there were over 3,600 deaths as a result of the conflict. On 10 April 1998 an agreement, The Good Friday Agreement, between the English and Irish people restored self-government to Northern Ireland and brought an end to the Troubles.
