Branches of the House of Romanov explained

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 II’s younger sons)
The Konstantinovichi (descendants of Grand Duke Constantine Nicholaevich of Russia)
The Nikolaevichi (descendants of Grand Duke Nicholas Nikolaevich of Russia)
The Mikhailovichi (descendants of Grand Duke Michael Nicolaevich of Russia)

The headship of the Imperial Family is in dispute between Grand Duchess Maria Vladimirovna of Russia of the Vladimirovich (Alexandrovichi) and Prince Andrew Andreevich of Russia of the Mikhailovichi branch.

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