Luxembourg
- Personal union with Bohemia, 1313–1378 and 1383–1388.
- Personal union with the Netherlands from 1815 to 1890, when King and Grand Duke William III died leaving only a daughter, Wilhelmina. Since Luxembourg held to Salic Law, Wilhelmina's distant cousin Adolphe succeeded to the Grand Duchy, ending the personal union.
