The I.R.A. of the time was divided into those members who wanted a ceasefire witha view to peace, and those that wished to continue armed resistance. In the mid Seventies, the group split into the Official IRA , who kept their weapons , but cached them and became political. The remainder became the Provisional IRA, and continued a campaign of violence, continuing , its limited capacity until today. This further split into the Real/Continuity IRA, who have continued up until the Omagh outrage, and since seemed to have mainly tailed away.
