Queen Elizabeth II was born on 21 April 1926 and ascended the throne in 1952 at the age of 25, following the death of her father, King George VI.

She married Prince Phillip, Duke of Edinburgh, in 1947, and together they had four children.

Her Reign spanned 70 years, making her the longest-serving monarch in British history

Throughout her life, she was a symbol of resilience and dedication, guiding the monarchy through decades of profound social and political change.

As Head of the Commonwealth, she fostered unity across diverse nations and remained a steadfast figure on the global stage.
