History of royal patronage of polar expeditions

The long history of royal patronage of polar expeditions was celebrated by Edward VII during the “Heroic Age” of exploration, starting the tradition of raising the Union Flag in the name of “King and Country”.

Queen Elizabeth II was the patron of the 1956 Commonwealth Transantarctic Expedition led by British explorer Vivian Fuchs and Sir Edmund Hillary of New Zealand.

In 1957, Prince Philip became the first member of the royal family to cross the Antarctic Circle. Following his death in 2021, the British Antarctic Territory lowered the Union Flag at Rothera Research Station.

The Princess Royal is a patron of the Great Britain’s Antarctic Heritage Foundation, and she visited Antarctica in 2002 to mark the centenary of Scott Base. She visited again in 2007.
