Leading political figures across the world have paid tribute to Queen Elizabeth II, and her seven decade-long reign.
President Michael D Higgins praised the "remarkable generosity of spirit" she demonstrated in responding to "a complex, and often difficult, history."
When Queen Elizabeth made an "historic State Visit to Ireland in 2011, the first such visit by a British monarch since Irish independence", President Higgins said that "she did so much through eloquent word and generous gesture to improve relations between our two islands".
"The Queen did not shy away from the shadows of the past", he said.
Taoiseach Micheál Martin conveyed his "deepest sympathy" to the British people and the royal family, and agreed that her visit to Ireland "was a great success".
He noted the queen's reign was one of "historic duration, immense consequence and a focus of respect and admiration around the world".
"Her dedication to duty and public service were self-evident," the Taoiseach said, adding that her passing was "the end of an era".
"Our world is a poorer place for her passing but a far richer and better place as a result of her long life and enduring contribution."
"Her commitment to and support for the Good Friday Agreement, reconciliation and mutual understanding was critical to advancing positive relations on these islands..."— RTÉ News (@rtenews) September 8, 2022
