Elizabeth and Albert -

Prince Albert and Lady Elizabeth were often seen together in the months and weeks before their marriage.

Ordinary people -

Fluency disorder -

A matter of concern, however, was the duke's relentless stammer, which affected his ability to deliver speeches and made him nervous and insecure. With Elizabeth's full support, he began seeing an Australian speech therapist, Lionel Logue, who helped the prince overcome his fluency disorder. The episode is portrayed in the acclaimed 2010 film 'The King's Speech,' with Colin Firth as the future King George VI, Helena Bonham Carter as Elizabeth, and Geoffrey Rush as Logue.

Family life -

Constitutional crisis -

In January 1936, King George V died. His oldest son, Prince Edward, Duke of Windsor ascended the throne as King Edward VIII. But just eight months into his reign, Edward abdicated the throne to marry the American divorcée Wallis Simpson, which caused a constitutional crisis. Subsequently, Albert became king—a position that he was reluctant to accept.

Coronation -

Second World War -

Neither had expected to end up king and queen. For her part, Elizabeth embraced her new status, and dedicated her life and that of her family's to serving her nation. Soon this responsibility was put to the test with the outbreak of the Second World War. In September 1940, London was heavily bombed. Among the buildings damaged was Buckingham Palace itself. The king and queen decided to see for themselves the devastation caused by enemy air raids, and toured places like the East End, an area particularly targeted.

Meeting the victims -

After gazing at bombed-out homes and meeting ordinary citizens who'd been left homeless or worse, injured, Elizabeth famously remarked that she felt she could "look the East End in the face."

Offering moral support -

In fact, the entire royal family stood firm with the nation throughout the conflict, with the king and queen effectively becoming symbols of the fight against fascism. The queen is pictured in 1944 with Princess Elizabeth as she chats with paratroopers preparing for D-Day.

In mourning -

In 1951, King George VI was diagnosed with lung cancer. He eventually succumbed to the disease on February 6, 1952. Princess Elizabeth and her husband, Philip, Duke of Edinburgh, immediately returned to London from an overseas tour—as queen and prince consort. Shortly afterwards, Elizabeth began to be styled as Her Majesty Queen Elizabeth The Queen Mother to avoid confusion with the new reigning monarch.

Widowhood -

Such was the grief at her loss that Elizabeth briefly considered retiring from public life. But an ingrained sense of duty and a stoic resolve led her to returning to the royal fold.

Matriarch -

She soon became the royal family's matriarch and found a new sense of purpose, which included chaperoning her daughter's children.

The Queen Mother -

In fact, Elizabeth soon became as busy as queen mother as she had been as queen consort. But throughout the rest of her life she was always careful not to overshadow her daughter's reign as queen.

Royal duties -

The Queen Mother continued to travel extensively throughout the United Kingdom, the Commonwealth, and beyond. A highlight of a 1954 tour to the United States was a visit to the top of the Empire State Building in New York City (pictured).

Love of horses -

Queen Elizabeth II inherited her mother's love of all things equine, especially horse racing. The Queen Mother owned several Thoroughbred race horses, and mother and daughter were often seen together on race day backing their favorite steed. They are both pictured at the prestigious Epsom Derby in 1965.

With Diana, Princess of Wales -

Royal Ascot was and remains one of the most eagerly anticipated sporting events on the social calendar. The Queen Mother rarely missed a year and was often seen arriving with other members of the royal family. She's pictured with Diana, Princess of Wales in 1990.

100 years old -

In later years, the Queen Mother was known for her longevity. On August 4, 2000, she celebrated her 100th birthday. On the day, more than 40,000 well-wishers gathered in the Mall to watch the Queen Mother and her two daughters step on to the balcony of Buckingham Palace. She's pictured arriving at the palace with then-Prince Charles, to whom she was particularly close.

Death -

In December 2001, the Queen Mother's health rapidly deteriorated. On February 9, 2002, her youngest daughter, Princess Margaret, died at the age of 71. Despite her frailty, she was able to attend the funeral. Her last public appearance was on March 5, 2002. On March 30, 2002, the Queen Mother died in her sleep at her home. She was 101. Pictured gathering at Westminster Abby for the funeral are senior members of the royal family.

Queen Elizabeth The Queen Mother is still applauded for her cheerful disposition and seemingly indomitable spirit, which earned her the nickname "Smiling Duchess." She remains one of the most popular— and much missed—members of the British royal family.
