In her teens Victoria fell in love with her maternal first cousin Grand Duke Kirill Vladimirovich of Russia, but the disapprobation of marriage between first cousins of his faith, Orthodox Christianity, discouraged their romance.

Their marriage was a failure.

In retaliation, the Tsar stripped Kirill of his offices and honours, also initially banishing the couple from Russia.
They had two daughters and settled in Paris before being allowed to visit Russia in 1909.
In 1910 they moved to Russia, where Nicholas recognized her as Grand Duchess Victoria Feodorovna.
After the fall of the Russian monarchy in 1917, they escaped to Finland (then part of the Russian Empire) where she gave birth to her only son.
