Doctor of Historical Sciences, Professor A.V. Manko reveals a little-known topic - dynastic ties of the House of Romanov with representatives of European ruling dynasties. Dynastic marriages have traditionally been given great importance as an important element of foreign policy, and the Romanovs followed the global tradition. The reader learns about the search for overseas brides for Tsar Mikhail Fedorovich, the founder of the dynasty; Information about the children and descendants of Emperor Paul I will be of undoubted interest. The morganatic marriages of Grand Duke Konstantin Pavlovich, Emperor Alexander II, Grand Dukes Mikhail Mikhailovich and Mikhail Alexandrovich are very interesting.
