Hsinbyumashin (Burmese: ???????????) was a senior queen of King Mindon Min during the Konbaung dynasty.
She was born Princess Supayagale c.
1821, the daughter of King Bagyidaw and his consort Nanmadaw Me Nu.She was wedded to Mindon Min, the penultimate king, who made her the high-ranking "Queen of the Central Palace" (????????????????????????).
Her full regnal title upon ascending the throne was Siripavaratiloka Maharajindadhipati Padumaratanadevi (????????????? ???????????????? ????????????).
On 25 November 1877, she received the title Hsinbyumashin, which translates to "mistress of the white elephants," upon receiving a white elephant named Sirimahasubhatta from King Mindon.Hsinbyumashin dominated the last days of King Mindon.
She was orchestrated the massacre of upward of 100 members of the royal family, it was an edict by Hsinbyumashin that ordered almost all possible heirs to the throne be killed, so that her daughter Supayalat and son-in-law Thibaw Min would become queen and king.
The ambitious Hsinbyumashin, after placing Thibaw on the throne, offered her oldest daughter Supayagyi, to be his queen.
During the royal aggamahesi coronation, Supayalat pushed in next to her sister to be anointed queen at the same time, breaking ancient custom.
The female lineage of Hsinphyumashin, her mother Nanmadaw Me Nu, and her daughter Supayalat in the male dominated Burmese monarchy is a very interesting one regarding the end of Independence and the monarchy.
