Royals from around the world united for the Queen's funeral — some were her close friends and others distant relatives. Take a look.

Margrethe II of Denmark, 82, became the longest-living reigning queen in Europe after the death of her friend and third cousin, Queen Elizabeth II, on September 8. 

She and the British monarch had a close relationship and referred to each other by their childhood nicknames, Town & Country Magazine reported. Queen Margrethe II said she'd call her "Lilibet," and that Queen Elizabeth II would call her "Daisy."

According to the outlet, Margrethe wrote that Queen Elizabeth II was "a towering figure among the European monarchs and a great inspiration to us all" in a condolence book for King Charles III. 

Stepping out for the somber occasion, Charlene — who has dealt with a series of health complications since 2021 — opted on wearing a long-sleeved black dress with a fascinator and black stilettos. She walked into Westminster Abbey with her arm around her husband, Prince Albert, who wore a military uniform. 

After Buckingham Palace announced the death of Queen Elizabeth II, Charlene said she'd been deeply saddened by the news in an Instagram post shared on September 9.

"A truly great lady whose dedication and service was recognized throughout the world during the 70 years of her reign," Charlene captioned a photo she posted of the Queen.

Queen Letizia and King Felipe VI of Spain were related to Queen Elizabeth II through her late husband, Prince Phillip, the Daily Express reported. 

According to the outlet, after the death of the Duke of Edinburgh in 2021, Felipe wrote a letter of condolence to the Queen referring to her by an affectionate nickname: "Aunt Lilibet."

Lilibet is the Queen's familial nickname. It was coined by her grandfather King George V when she was a child.

Princess Beatrix was Queen of the Netherlands for 33 years before she abdicated the throne to her son, King Willen-Alexander, in 2013. 

In the Channel 5 2021 documentary "Beatrix: The Queen Who Gave Up The Crown," royal journalist Tina Adebayo said Princess Beatrix and Queen Elizabeth II were "close friends and confidants."

"It's not very many people that understand what it's like to be the queen of a country," she added. "They're united by being quite lonely at the top." 

Emperor Naruhito had known Queen Elizabeth II for nearly 50 years, according to The Japan Times.

He first met the Queen in 1975, when Elizabeth visited his parents — Emperor Emeritus Akihito and Empress Emerita Michiko — during the only visit to Japan she'd make during her lifetime. 

Emperor Naruhito later joined the Queen for tea at Buckingham Palace while studying at Oxford University in 1983. The following year, he spent time with the Queen and Prince Philip at Balmoral Castle, telling an aide that it felt as if he were "a member of the family." 

King Philippe of Belgium is the Queen's third cousin, according to Wales Online. 

King Charles III represented the British monarchy during Philippe's wedding to Queen Mathilde in 1999. 

Bolkiah is now the world's longest-reigning monarch following the Queen's death earlier this month. He has served as the Sultan of Brunei since 1967. 

According to Arab News, Bolkiah had a close relationship with the Queen, who knighted both him and his father. 

Queen Rania of Jordan sported the same black coat she had worn to visit the Queen during a visit to Windsor Castle in 2001, according to The National News.

Earlier this week, Queen Rania told ITV that Queen Elizabeth II had been a "guiding hand" during her reign. 

"To me, she is the Queen of the world," Queen Rania said. "She may be the Queen of England but I think symbolically she is the Queen to all of us."

King Harald V told King Charles III that he was mourning "the loss of a dear relative and confidant friend," according to The Local. 

"For nearly a century, Her Majesty devoted her life to the service of the Commonwealth, following the British people through good days and bad, in times of happiness and sorrow," his statement read. "We send our deepest condolences to the British people on the loss of their beloved Queen." 

King Carl XVI Gustaf was the Queen's third cousin. Queen Victoria was the great-great-grandmother of both royals, according to Hello! Magazine. 

The king shared a moving tribute to Queen Elizabeth II on Instagram, including photos of the Queen's state visits to Sweden.
