The country has fallen silent to remember its war dead at services across the country as the Queen led the nation in honouring the fallen.
At the Cenotaph memorial in London, the monarch laid the first wreath to commemorate members of the Armed Forces who died fighting in all conflicts since the First World War.
In brilliant autumn sunshine, senior members of the monarchy joined Prime Minister David Cameron, military chiefs, servicemen and women and thousands of watching spectators in paying their respects.
When the first stroke of eleven sounded from nearby Big Ben, Whitehall observed a two-minute silence only punctuated by the hum of distant London traffic and birds.
The Queen laid the first wreath, followed by the Duke of Edinburgh.
Then the Duke of Cambridge, wearing his RAF uniform, laid a wreath, under the gaze of the Duchess of Cambridge, who watched from a balcony at the Foreign Office alongside the Countess of Wessex and the Princess Royal's husband Vice Admiral Sir Timothy Lawrence.
William was followed by the Duke of York, the Earl of Wessex, the Princess Royal, Prince Michael of Kent and Field Marshal Lord Guthrie of Craigiebank.
Wreaths were also laid by Mr Cameron, Liberal Democrat leader Nick Clegg, opposition leader Ed Miliband and Westminster Plaid Cymru group leader Elfyn Llwyd, as well as high commissioners from Commonwealth countries and leaders of the Armed Forces.
The Prince of Wales and Duchess of Cornwall earlier attended a ceremony in Auckland as part of their Jubilee tour of New Zealand. Under grey skies the royals sat with New Zealand's prime minister John Key, veterans from across the decades, and members of the public around the Auckland Cenotaph.
The Duke of Kent was also overseas, representing the Queen at a service in the Falkland Islands.
