British Monarchy Name Change in 1917, from Saxe-Coburg-Gotha to Windsor
The name Saxe-Coburg-Gotha came to the British Royal Family in 1840 with the marriage of Queen Victoria to Prince Albert, son of Ernst, Duke of Saxe-Coburg & Gotha.
King George V changed the name of the British Royal Family from the German Saxe-Coburg and Gotha to the English Windsor, on 17 July 1917, following high anti-German sentiment amongst the people of the Britain during World War when the German Gotha G.I began bombing London directly and became a household name in March 1917. (The Gotha G.I was a heavy bomber used by the German Air Service during World War I)
This returned to Monarchy to a British name, and was received well by the British public, shaking off the old German links.
