What nickname reflects Queen Victoria's royal descendants across Europe?

The nickname reflecting Queen Victoria’s royal descendants across Europe is “Grandmother of Europe.”

Victoria and her husband, Prince Albert, had nine children, and many of them married into Europe’s ruling families. Their descendants eventually occupied or married into several royal houses, including those of Britain, Germany, Russia, Greece, Spain, Norway, and Romania.

The nickname is especially memorable because Victoria’s grandchildren included Kaiser Wilhelm II of Germany and Alexandra, the empress of Russia. Her descendants were linked to both sides of the European dynastic network before the First World War, although family relationships did not prevent political conflict.

The phrase is descriptive rather than an official title. Victoria was not literally the grandmother of every European monarch, and other royal matriarchs have sometimes received similar labels. Still, her unusually extensive family connections made “Grandmother of Europe” the standard quiz answer.
