By far the world's largest non-governmental landowner, Queen Elizabeth II was the head of the British Commonwealth from 1953 until her death on 8 September this year. As a result, she was technically the legal owner of around 2.7 billion hectares of land, as estimated by The New Statesman. This equates to around a sixth of the planet's land surface, which now belongs to King Charles III as the new British monarch.

The Crown Estate includes prime chunks of London, massive tracts of agricultural land in rural Britain, and around half of the UK's foreshore. The Crown also owns over 90% of the land in Canada, where King Charles III is now Head of State. However, the land cannot be sold by the reigning monarch and isn't considered their private property.
