She was accompanied by Prince Charles after her 96-year-old husband, Philip, was taken to hospital with an infection.
His rare absence from the State Opening of Parliament added to the solemnity of an occasion cherished by the British people and replete with historical tradition. While his predecessor Barack Obama said Britain would be "at the back of the queue" if it voted to leave the European Union, Trump initially promised a quick deal with the United Kingdom before appearing to prioritize an agreement with the bloc it is leaving.
The speech announced no fewer than eight bills to implement Brexit, and new legislation aimed at tackling extremist content online after the terror attacks.
But flagship manifesto policies which find no place in the Conservative agenda included the scrapping of universal free school lunches, means-testing of the winter fuel payment, an energy price cap and the reform of social care funding which opponents branded a "dementia tax".
The prospect of Trump being greeted with demonstrations was only one aspect of planning for the proposed visit by the head of state of a crucial ally to Britain.
"An invitation has been extended and accepted".

Donald Trump's state visit to Britain appears to have been postponed, as it has been left out of the Queen's Speech.
In written remarks introducing the government plan, Mrs May admitted that the election result was not what she had hoped for.
"We will work hard every day to gain the trust and confidence of the British people, making their priorities our priorities".
The nine-minute speech reflected May's diminished position - a loss of stature that has emboldened those within her own party who want a "softer" Brexit which makes a less-sharp break with the EU.
She also tried to be softer period.
Parliament now has several days to debate and vote on the speech's proposals.
Mrs May is under increasing pressure to secure a deal with Northern Ireland's Democratic Unionist Party to prop up her government after almost two weeks of talks.
"As prime minister, I apologise for that failure", she said.
Jeremy Corbyn, leader of the opposition Labour Party, whose surprisingly strong election performance damaged May, called the speech "thin gruel".
While Wednesday's speech is being used by some as an indication that a Trump state visit is off the cards, recent history could indicate otherwise.
The event is usually filled with pomp and circumstance, like royal robes and a horse-drawn carriage.
