Britain paid respect to her war dead during a two minutes' silence starting at 11am this morning as Remembrance Sunday was marked across the country.
Thousands gathered at the Cenotaph memorial in Whitehall to honour those killed in World Wars One and Two and later conflicts.
The monarch, Prime Minister David Cameron, Labour leader Jeremy Corbyn, Liberal Democrats leader Tim Farron, SNP leader in Westminster Angus Robertson and DUP leader in Westminster Nigel Dodds each laid wreaths at the base of the Cenotaph.
The Queen was joined by royals including the Duke of York, Prince William and Prince Harry at the wreath-laying ceremony.
Previous prime ministers Gordon Brown and Tony Blair also paid their respects, along with religious ministers, military leaders and dignitaries from around the Commonwealth.
King Willem-Alexander of the Netherlands also laid a wreath at the Cenotaph after he was invited by his distant cousin Queen Elizabeth II to mark the 70th anniversary of the liberation of his country following the end of World War Two.
This year's service at the Cenotaph was shorter than in previous years, in an effort to reduce the amount of time the ageing war veterans and the Queen are made to stand.
Events have also taken place around the UK, including in Edinburgh, where Scotland's First Minister Nicola Sturgeon laid a wreath.
The UK's war dead have already been honoured at the annual Festival of Remembrance, which was attended by the Queen and other royals, at London's Royal Albert Hall on Saturday evening.
During the event, the Book of Remembrance was delivered to the stage by Corporal Anna Cross, a reservist with the Queen Alexandra's Royal Army Nursing Corps who travelled to Sierra Leone to help with the devastating Ebola outbreak.
Highlights included a reading from 94-year-old veteran Bob Hucklesby, of Dorset, who served with the 560th Field Company Royal Engineers and spent four years in a Japanese camp.

Cdr Duncan McClement from the Royal Navy said those killed in and conflicts old and new should never be forgotten
Speaking ahead of the service, Cdr Duncan McClement, from the Royal Navy, told the BBC the country must not forget those personnel serving today in conflicts around the world.
"There are also families for which this is the first Remembrance Sunday, who have lost loved ones on active service, and it's important that they, like all the others before through the great wars and all conflicts since then, are always remembered and never forgotten."

"You had to be determined. If you ever gave up, you were dead in three days," he said.
The Festival of Remembrance began in 1927 and was originally intended to honour the sacrifices of those who died in World War One.
However, it now includes tributes to the war dead from all past and more recent conflicts.
This year marks a number of other significant anniversaries in the UK's military history, including the 75th anniversary of the Battle of Britain.
