Nicholas II Dadiani of Bosnia (January 4, 1847- March 20, 1889) was an Georgian Noble who was elected King of Bosnia in 1887 after the Bosnian Rebellion of 1886. he was supported by the Russians and was given the throne in turn for Russian military support.
Niko Dadiani was born in Zugdidi, Mingrelia's capital, in 1847. Niko was six years old in August 1853 when his father died, and he became Prince of Mingrelia as an autonomous subject of the Russian Empire. With the approval of Tsar Nicholas I, Niko was placed under the regency of his mother, Princess Ekaterina; the Russian bureaucrat Kornely Borozdin was assigned to him as a tutor. The regency council also included Niko's paternal uncles, Grigol and Konstantin.
Niko remained in St. Petersburg, enjoying the favor of the imperial family even after his mother hurried home due to a peasant revolt in Mingrelia in May 1857. The revolt was exploited by the Russian government as a pretext to recall Princess Ekaterina back to St. Petersburg and to place the hitherto autonomous principality under a provisional Russian administration. Niko Dadiani was then sent for further education in Paris. On his return, Niko, persuaded to accept a fait accompli, renounced his hereditary title of Prince Regnant of Mingrelia on 4 January 1867.
