How did the Windsor dynasty come about?

The Windsor dynasty originated in 1917 when King George V, in response to anti-German sentiment during World War I, changed the family name from the House of Saxe-Coburg and Gotha to the House of Windsor, named after Windsor Castle. This change symbolized a shift towards a more British identity. The royal family's rebranding aimed to strengthen public support and solidarity during the war, and the name Windsor has since been synonymous with the British monarchy.
