Crowned in 1953, Queen Elizabeth II became the longest-serving British monarch in September 2015, surpassing her great-great grandmother Queen Victoria. In May 2022, she overtook Thailand’s King Bhumibol Adulyadej, who reigned for 70 years and 126 days between 1927 and 2016, to set another record to become the world’s second-longest reigning monarch in history.
