Queen Elizabeth II reigned for more than 70 years and for 30 years during that time a vicious conflict was fought in the part of her United Kingdom known as Northern Ireland.
About 3,600 people were killed and more than 30,000 wounded from 1969 until the signing of an agreement in 1998, which largely brought peace between those fighting against British rule in the northern province of Ireland, and those battling to preserve and defend the union with Britain.
