The Grand Duke was a supporter of the liberal (sometimes referred to[by whom?] as "enlightened") bureaucrats during the period of his brother Alexander II's great reforms. He served as chairman of the Imperial Russian Geographical Society (founded in 1845). The Geographical Society was subordinate to the Ministry of Internal Affairs, which was home to a conspicuous number of liberal bureaucrats [ru], including Nikolai Miliutin.

In addition to his support of and participation in the 1861 emancipation of the serfs, the Grand Duke also instituted reforms in the Imperial Russian Navy from 1854.

Konstantin's brother[which?] was supposed[by whom?] to have said: "Let the Poles have their own court and intrigues." Though the Grand Duke tried to show a liberal attitude towards the Poles, his efforts came too late and he was recalled with the outbreak of the January Uprising in 1863.


Konstantin married Alexandra of Saxe-Altenburg in 1848; they had six children.

At the end of the 1860s, Konstantin embarked on an affair, having an illegitimate daughter, Marie Condousso.

Konstantin had five illegitimate children with his mistress Anna Kuznetsova (1847–1922); they bore the last name Knyazev:

  • Sergey Konstantinovich Knyazev (1873–1873)
  • Marina Konstantinovna Knyazeva (8 December 1875 – 8 June 1941); m. 24 April 1894 Alexander Pavlovich Yershov (b. 6 July 1861), son of Gen. Pavel Yershov
  • Anna Konstantinovna Knyazeva (16 March 1878 Saint Petersburg – 5 February 1920); died of typhoid fever, (m.) 29 April 1898 in Saint Petersburg to Nikolay Nikolayevich Lyalin (15 August 1869 – 14 February 1920); died of typhoid fever, son of Gen. Nikolay Lyalin, Military Governor of Helsingfors; their son was the Benedictine theologian Dom Clément Lialine
  • Izmail Konstantinovich Knyazev (1879–1885); died of scarlet fever
  • Lev Konstantinovich Knyazev (1883–1885); died of scarlet fever

Konstantin was the paternal great-grandfather of Charles, Prince of Wales, heir apparent to the British throne, since his daughter Olga married George I of Greece, whose son Andrew married Alice Battenberg, and they became the parents of Philip, Charles' father.
