As the world mourns Great Britain’s Queen Elizabeth II, the longest-serving monarch in her nation’s history, U.S. officials note her constancy as a friend to the United States during her 70-year reign. She met with almost every U.S. president since Harry Truman and paid multiple visits to the United States with her husband, Prince Philip, Duke of Edinburgh.

President Biden and first lady Jill Biden said that Queen Elizabeth II was “more than a monarch. She defined an era.”

“Queen Elizabeth II was a stateswoman of unmatched dignity and constancy who deepened the bedrock Alliance between the United Kingdom and the United States,” the Bidens said.

Secretary of State Antony Blinken issued his deepest sympathies to the royal family and said that he, like other Americans, “will forever be inspired by the memory of her service, leadership, and friendship.”

Here are photos that trace the queen’s visits with 13 of the 14 U.S. presidents whose terms fell during some portion of her long reign. (Although the queen never met President Lyndon Johnson, her husband and sister did, and she carried on a correspondence with him.)

President Truman welcomed Britain’s then-Princess Elizabeth and her husband, the Duke of Edinburgh (who became a prince of the United Kingdom after his wife took the throne). Greeting the couple, Truman expressed the warm hope that “when you leave, you will like us even better than when you came.”

Here, the princess rides with Truman in a motorcade, following a reception ceremony at Washington National Airport on October 31, 1951.

We send our deepest condolences to the Royal Family, who are not only mourning their Queen, but their dear mother, grandmother, and great-grandmother. Her legacy will loom large in the pages of British history, and in the story of our world.”
