Branches of the Russian Imperial Family

The Russian Imperial Family was split into four main branches named after the sons of Emperor Nicholas I:

The Alexandrovichi (descendants of Emperor Alexander II of Russia) (with further subdivisions named The Vladimirovichi and The Pavlovichi after two of Alexander IIs younger sons)
The Konstantinovichi (descendants of Grand Duke Constantine Nicholaevich of Russia)
The Nikolaevichi (descendants of Grand Duke Nicholas Nikolaevich of Russia)
The Mihailovichi (descendants of Grand Duke Michael Nicolaevich of Russia)

The headship of the Imperial Family is in dispute between Prince Dimitri Romanovich of Russia of the Nikolaevichi branch and Grand Duchess Maria Vladimirovna of Russia of the Vladimirovichi. See the article line of succession to the Russian throne for more details on the dispute.

In the family trees, a ≈ sign represents a union causing an illegitimate child.
