Queen Elizabeth II, currently the world's longest-reigning monarch, turns 93 on April 21st.
Starting even before she ascended to the throne in 1952, the queen has played a major role in facilitating the US and UK's "special" diplomatic relationship and has met with 12 American presidents at places including Buckingham Palace, the White House, and even a Baltimore Orioles game.
She traveled to Washington, DC for the first time to meet President Harry Truman in 1951 when she was a still a princess, and most recently hosted President Donald Trump at Windsor Castle last year when he visited England.
