Services were held across the United Kingdom and, in the centenary year of the start of the First World War, were especially poignant.
Churches held special events as well as memorials being held in most town centres.
In London the Queen joined political and military leaders in laying a wreath at the Cenotaph.
Two minutes silence was observed at 11am to remember all those who have died in conflict.
Meanwhile a Durham school's hosted a joint Remembrance Sunday service for Christians and Muslims.
The rise of Islamic State was one of the key issues addressed at the event at St. Bede's Catholic School & Sixth Form College.
Organiser Fr. Dan Fitzpatrick told Premier the event was to bring people together and 'dispel any myths' around Islam.
He said: "It is really to dispel any myths where people are connecting what is happening with the terrorist groups in the Middle East with the Muslim community in our own country."
But he accepted there could be some tension between the faiths because of the rise of Islamic State militants.
He added: "We have anticipated maybe some awkward questions.
"We had a meeting with the young people in the school and they have prepped some questions."
