Queen Elizabeth II’s reign began in 1952 when the 25-year-old learned that her father died. Over the decades, Queen Elizabeth II became a cherished institution, often with her beloved corgis at her side. She kept a stiff upper lip as the marriages of three of her children broke up and a fire swept through Windsor Castle within the same year. During her reign, Queen Elizabeth II met with 13 U.S. presidents. Now, the world mourns the monarch who seems to have been a part of our lives forever.
