Line of succession to the former throne of Württemberg

The monarchy of Württemberg came to an end in 1918 along with the rest of the monarchies that made up the German Empire. The last member of the dynasty to reign as King of Württemberg was William II.

With the death of William II in 1921, succession to the royal claim bypassed the former Duke of Teck and the Duke of Urach, both of whom descended from morganatic marriages, and the headship of the royal house was inherited by Albrecht, Duke of Württemberg, of the Roman Catholic, Altshausen branch of the royal family. The current head of the House of Württemberg is Carl, Duke of Württemberg. His elder brother Duke Ludwig Albrecht had previously renounced his succession rights for himself and his issue.

The succession is determined by Article 7 of the 1819 Constitution of the Kingdom of Württemberg, which states, "The right of the succession to the throne belongs to the male line of the royal house; the order of the same is determined by the succession of lines according to primogeniture."[1] The current order of succession is:

Duke Albrecht (1865–1939)
- Duke Philipp Albrecht (1893–1975)
  - Duke Carl (born 1936)
    - Duke Friedrich (1961–2018)
      - (1) Duke Wilhelm (born 1994)
    - (2) Duke Eberhard (born 1963)
      - (3) Duke Alexander (born 2010)
    - (4) Duke Philipp (born 1964)
      - (5) Duke Carl Theodor (born 1999)
    - (6) Duke Michael (born 1965)
- Duke Albrecht Eugen (1895–1954)
  - (7) Duke Ferdinand Eugen (born 1925)
  - (8) Duke Eugen Eberhard (born 1930)
  - (9) Duke Alexander Eugen (born 1933)
