House of Windsor

The House of Windsor is the reigning royal house of the United Kingdom and the other Commonwealth realms. King Charles III has been head of the House since 2022.

History
The Windsor name was adopted on 17 July 1917 by King George V of the House of Saxe-Coburg and Gotha due to anti-German sentiment during the First World War. The royal proclamation issued by George V stated:

"Now, therefore, We, out of Our Royal Will and Authority, do hereby declare and announce that as from the date of this Our Royal Proclamation Our House and Family shall be styled and known as the House and Family of Windsor, and that all the descendants in the male line of Our said Grandmother Queen Victoria who are subjects of these Realms, other than female descendants who may marry or may have married, shall bear the said Name of Windsor...."

After the accession of Queen Elizabeth II, who was married in 1947 to Philip Mountbatten (born Prince Philip of Greece of Denmark of the House of Schleswig-Holstein-Sonderburg-Glücksburg), she decreed that her children would continue to be known as the house and family of Windsor. Following a further decree in 1960 the family name was changed to Mountbatten-Windsor for her descendants in lieu of the name Windsor. The House name remained Windsor.

The male line descendants of Prince Philip and Queen Elizabeth II carry the surname Mountbatten-Windsor. The male line descendants of King George V carry the name Windsor, the only other branch of the family to use the Windsor surname was the Duke of Connaught branch of the family which went extinct in the male line in 1943 upon the death of Alastair Windsor, 2nd Duke of Connaught and Strathearn.
