To the blare of bugles and the sad skirl of bagpipes, Great Britain bid a last farewell today to the nation's favorite centenarian, Her Majesty Queen Elizabeth the Queen Mother, who was laid to rest amid ancient ritual and military pageantry.

More than a million people lined the streets of a hushed, solemn London as the mother of Queen Elizabeth II was carried -- in an ornate coffin topped with the 106-carat Koh-i-Noor diamond -- from the ceremonial funeral service at Westminster Abbey to the royal vault at Windsor Castle, west of London. There the Queen Mother will rest beside her husband, King George VI.

Crowds lined nearly all of the 23-mile route, throwing flowers onto the road as the black hearse cruised by. Police said they stopped counting the mourners when the tally topped 1 million.

Before the funeral service began, the abbey's deep tenor bell was rung 101 times -- one chime for each year of the Queen Mother's long, eventful life.

Born in the reign of Queen Victoria, she married a duke who never expected to become king -- and then became queen herself when her husband was thrust onto the throne in 1936. After his death in 1952, she took on the new title "Queen Mother." Her obvious zest for life made her a popular favorite for the next 50 years, even as scandal and turmoil tainted other members of the royal family.

At one point during the hour-long funeral, a royal functionary, the Garter King of Arms, read a lengthy list of the various titles the late queen had held, including "Lady of the Imperial Order of the Crown of India," "Dame Grand Cross of the Royal Victorian Order upon whom had been conferred the Royal Victorian Chain," and "Lady of the Most Ancient and Most Noble Order of the Thistle."

But the deceased's most popular title was emblazoned on a handmade banner held by a family outside the church: "Goodbye, Queen Mum."

For the 75-year-old Elizabeth II, the loss of her mother is the second sad occurrence in a year when the country is celebrating her Golden Jubilee after 50 years on the throne. Two months ago, Elizabeth's sister, Princess Margaret, died at the age of 71.

Queen Elizabeth II went on national television Monday night to thank the people of Britain for "the outpouring of affection which has accompanied" her mother's death. Referring to the crowds that waited hours to file past the Queen Mother's coffin over the weekend, Elizabeth II said, "The extent of the tribute . . . has been overwhelming."

The queen said she hoped that, at today's funeral, "sadness will blend with a sense of thanksgiving, not just for her life but for the times in which she lived -- a century for this country and commonwealth not without its trials and sorrows, but also one of extraordinary progress."

Some 2,100 people jammed the 1,000-year-old Westminster Abbey for the funeral service. It was unusual in that non-Anglican clergy were invited to take part along with the chief cleric of the Church of England, Archbishop of Canterbury George Carey.

There were members of 25 royal families from around the world and prime ministers from several former colonies that still consider the British monarch head of state. First lady Laura Bush represented the United States. The Queen Mother's longest-serving butler, Billy Tallon, who held the title "Page of the Backstairs" and served her for more than half a century, was given a seat of honor.

The entire British royal family was present, with many members in gleaming ceremonial military uniforms. A former royal, Sarah Ferguson, ex-wife of Prince Andrew, fourth in line to the throne, was invited. So was Camilla Parker Bowles, the close companion of Prince Charles, the man who is due to become king when the reign of his mother, Elizabeth II, comes to an end.

The Queen Mother was no stranger to ornate royal ceremonies at Westminster Abbey. It was there, 79 years ago this month, that a Scottish lass named Elizabeth Bowes-Lyon married the second son of King George V.

Then, after her husband's older brother, King Edward VIII, suddenly gave up the throne in order to marry a divorced woman, Elizabeth found herself back in the abbey in 1936 to be crowned "Queen Consort" as her husband became King George VI.

The new king was a nervous, stuttering, shy man who had never wanted to reign. The official biographies all agree that his forceful, energetic wife gave him the strength he needed to lead Britain through the dark days of World War II and the subsequent breakup of Britain's global empire. During the Nazi blitz in 1940, when advisers urged the queen to flee London with her two daughters for a safe haven in Canada, she flatly refused: "I won't leave the king, and the king will never leave."

As a memorial to her wartime role, the Royal Air Force today staged a special flyover as the funeral procession headed away from the abbey. Three World War II airplanes -- a Lancaster bomber and two Spitfire fighters -- flew low over the cortege as it moved slowly down the Mall outside Buckingham Palace.

In the half-century since her daughter assumed the throne, the "Queen Mum" was known, and widely admired, for her love of horse racing and her daily habit of marking the noon hour with a cocktail of gin and Dubonnet on ice.

In the past decade, as criticism grew of the royal family and its luxurious, taxpayer-subsidized lifestyle, the Queen Mother came in for her share of comment. She kept a personal staff of 40 and complained that she could never manage to balance her checkbook, despite a $900,000-per-annum public subsidy and a generous allowance from her daughter.

For all that, though, she remained the most popular of the royals, cheered and admired by those who looked up to her during World War II -- and by their grandchildren. "She remained young at heart," Archbishop Carey said in his sermon at the funeral, "and the young themselves sensed that."
