Which British king visits Downton in the 2019 film?

The British king who visits Downton Abbey in the 2019 film is George V. The film is set in 1927, when the Crawley family receives news that King George V and Queen Mary plan a royal visit during their tour of Yorkshire.

George V was king of the United Kingdom from 1910 until his death in 1936 and was also Emperor of India. His visit gives the film its central event: the household must prepare Downton for an official royal dinner, while the servants struggle with the demanding members of the royal staff.

A common mix-up is confusing George V with his sons. Edward, Prince of Wales, later became Edward VIII, while Prince Albert, Duke of York, later became George VI. Both appear in the wider royal setting of the film, but neither is the visiting king. George V’s wife, Queen Mary, accompanies him, making the royal couple the guests of honour at Downton.
