Among them were the only surviving grandchildren of the last monarch – Princess Hteik Su Phaya Gyi and Prince Taw Phaya, now both in their 90s.

“When we were young we used to come and play here,” a beaming Taw Phaya, dressed in traditional maroon sarong and cream jacket, told AFP inside the audience hall where his grandfather once ruled from on high. “The British tried to keep us away from the common people. But... today the common people will pay respects to royalty,” he added.

Thibaw was only on the throne for seven years before British troops swept into Mandalay on November 28, 1885 and ordered his family to leave the country the very next day.

The sight of the monarch and his heavily pregnant wife being paraded through the streets on old bullock carts as his subjects wept and prostrated themselves was a humiliation that has been seared on Myanmar’s collective memory ever since.

Fearing the royal family would become a focus for dissent, the British closed off the palace to the public and the doors remained shut after independence in 1948.

The brutal junta that seized power in 1962 also sidelined the family, seeking instead to reinvent themselves as the successors to the warrior kings of old during a half-century rule that ruined Myanmar’s economy and closed its people off from much of the outside world.

But interest in the monarchy reignited under the quasi-civilian government that took power five years ago when former president Thein Sein, a reformist general, visited Thibaw’s tomb in the Indian seaside town of Ratnagiri.

Myanmar’s remaining royals, who used to gather in secret for their commemorations, have seized on the renewed interest in their family this year. In October they held a ceremony to commemorate the death of Thibaw’s father King Midon while Tuesday’s gathering was the first time they have public marked the fall of their dynasty.

The family also plan to hold a commemoration in India in December to mark Thibaw’s death in 1916.

One of Thibaw’s great-grandsons, Soe Win, has described the commemorations as a chance to restore “the [lost] human dignities of our country”.

Experts say the public gathering of royals will help Myanmar rediscover a critical period in its history as it embarks on a hopeful and more open future under the democratically elected government of Aung San Suu Kyi.

“Burmese self-identity congealed around a very defensive attitude to the outside world, because that period of the Burmese kingdom was also a period of extreme threat,” historian Thant Myint U told AFP. Hla Nyunt Yi, a 48-year-old vendor from western Rakhine state who attended the ceremony, said she had mixed feelings about seeing what remains of Myanmar’s once mighty royal line.

“I feel happy and sad at the same time seeing the king’s relatives here,” she said.
