Limban Mibaya

Thiri Thu Sandar Dewi (; ), commonly known as Limban Mibaya , was a queen of the fourth rank of King Mindon during the Konbaung dynasty in Burma. She was one of the queens of the Royal Treasury (ရွှေတိုက်စာရင်းဝင် မိဖုရား) and later promoted to Devi-ranked queen—one of the highest distinctions bestowed upon a queen consort in the Konbaung dynasty.

Life and family Limban Mibaya was born in 1830 to Tharbyu (also Minyon), mayor of Kanaung and Myanaung and his second wife Thakhingyi Khin-U Shinma. She was the elder sister of Thetpan Mibaya.

Her father's first wife gave birth to Khin The, and so Limban Mibaya and the Queen of the Northern Palace were half-sisters (having the same father).

When her father died, her mother married an officer of Kyaukpadaung and gave birth to Tharazein Mibaya, Maung Lay Nge, and Maung Thudaw. Thus, Limban Mibaya and Tharazein Mibaya were also half-sisters (sharing the same mother).

Life in palace Limban Mibaya became a kollotaw of Prince Mindon, at the age of 16. When King Mindon ascended the throne, she became a fourth-rank queen and received the appanage of Limban and later received Bamaw and Magway.

She was part of the queen faction led by Kunitywa Mibaya, which opposed Hsinbyumashin, the Queen of the Central Palace. Other members included Thetpan and Nanda Dewi, the Second Queen of the Northern Apartment. In 1877, the group petitioned King Mindon to prevent Hsinphyumashin from being appointed the new chief queen following the death of Chief Queen Setkya Dewi. During the final days of King Mindon, Queen Hsinbyumashin wielded considerable influence over court affairs. She ordered the arrest of several princes and installed her protégé, Prince Thibaw, as the heir to the throne.

Due to their opposition, Hsinbyumashin harbored deep resentment toward the faction. After King Thibaw ascended the throne, she ordered the arrest of its members. Limban, Thetpan, and Kunnitywa were imprisoned, while Nanda Dewi, the Second Queen of the Northern Apartment, was executed. Her younger son Yanaung Prince, along with his consorts, were executed during the Bronze Hall Massacre—an event in which over 100 members of the royal family were killed—following an edict by Queen Hsinbyumashin to eliminate nearly all potential heirs to the throne. Limban and her eldest son Kyapin Prince were released from prison only two years before the fall of the Konbaung dynasty in 1885. Her daughter, Salin Supaya, shaved her head and entered the Buddhist order of nuns permanently, immediately after her father, King Mindon, was entombed.

Issues King Mindon and Limban Mibaya had four sons and a daughter, but second and third sons did not survive– only Salin Supaya, Kyapin Prince and Thiri Thu Dhammaraja Yanaung Prince alive to adulthood.

Her eldest daughter, Salin Supaya, was the Tabindaing Princess (chief queen designate) during the reign of King Mindon.

As the saying goes "Son Kyapin, daughter Salin," children of Limban Mibaya were the favorites of King Mindon.
