The development of these institutions was supported by acts such the visit of efforts by Mary Robinson (as President of Ireland) to the Queen Elizabeth II (Queen of the United Kingdom), an apology by Tony Blair (as Prime Minister of the United Kingdom) to Irish people for the failures of the British Government during the Great Famine of 1845—1852 and the creation of the Island of Ireland Peace Park. A state visit of Queen Elizabeth II to Ireland in May 2011 – including the laying of a wreath at a memorial to IRA fighters in the Anglo-Irish war – symbolically sealed the change in relationships between the two states following the transfer of police and justice powers to Northern Ireland. The visit came a century after her grandfather, King George V, was the last monarch of the United Kingdom to pay a state visit to Ireland in July 1911, while it was still part of the United Kingdom.
