A notable connection was the marriage of Grand Duke Konstantin Konstantinovich of Russia, a member of the Romanov family, to Princess Zlata of Serbia, a daughter of King Peter I of Serbia, from the Karadjordjevic family. This union took place in 1889, establishing a direct familial link between the two royal dynasties.
Through this marriage and other familial connections, the Russian and Serbian royal families shared common bloodlines and had strong ties that extended beyond political and diplomatic relationships. These connections played a significant role in fostering cultural and historical links between Russia and Serbia, leading to enduring ties between the two nations.
