An estimated one million mourners lined the streets of London during the funeral proceedings of Queen Elizabeth II with an unspecified number of people missing the procession due to train cancellations on various lines. The monarch, one of the longest-reigning in recent history, was interred in the King George VI Memorial Chapel at Windsor Castle after the official and highly televised procession and service on September 19. As our chart based on media reports and Statista research shows, the Queen's funeral was only one of four attended by more than one million people in the United Kingdom since the 19th century.
The other three deceased drawing crowds of this size in the UK were Princess Diana in 1997, the Queen Mother in 2002 and Arthur Wellesley, 1st Duke of Wellington, in 1852. Wellesley's funeral also saw the largest estimated number of mourners on site. According to contemporary reports, 1.5 million people gathered to pay their respects to the former prime minister and soldier who played an instrumental role in the victory in the Napoleonic Wars.
Beating the United Kingdom in terms of the most funerals attended by more than one million people over the last 200 years is India, where eleven such proceedings drew crowds of the corresponding size. The biggest by this definition, in India and worldwide, was the funeral of C.N. Annadurai, a Tamil politician who held the post of Chief Minister of Madras State from 1967 until his death in 1969. Annadurai's funeral was attended by an estimated 15 million people.
