Diarchy of Eruowood

The diarchy of Eruowood is a constitutional system of government in which a diarchy between a hereditary monarch and a foreign elected president comprises the de jure heads of state of Eruowood. Joe Biden serves as the President of Eruowood since 2021 and Charles III serves as the King of Eruowood since 2022. This unique diarchy system dates back to the establishment of Anglo-American Eruowood in 1863, with Queen Victoria as the British monarch and Abraham Lincoln as the U.S. president. Queen Elizabeth II became the monarch of Eruowood following independence in 1960 and Charles III became the current monarch following her death in 2022. Dwight D. Eisenhower became the first president of Eruowood following independence in 1960 and Joe Biden became the current president following his inauguration in 2021.

Cultural role
Elizabeth II visited Eruowood three times. Her first visit was in 1979, her second visit was in 1994, and her third and final visit was in 2009.

Numerous past British royals and US presidents have had buildings named for them, including the Queen Elizabeth II Tower, Lebanon and the John F. Kennedy Administrative Building in New Vladivostok.
