Input: Question: How many years was the royal house named the House of Saxe-Coburg and Gotha before it was changed? Passage:The programme explores the lives of King George V and Queen Mary, and their attempts at modernising the British Monarchy in response to the massive social changes during and following World War I. The first episode recalls how, fearing anti-German sentiment, the royal house name was changed by King George from the House of Saxe-Coburg and Gotha to the House of Windsor. The series also examines the personal lives of the couple, delving into their relationships with their children, and with each other. The marriage between George and Mary was an arranged marriage, occurring only because Prince Albert Victor, George's brother and Mary's original fiancé, died from influenza. George V is presented in the series as a disciplinarian, who strictly punished his children, but was known to be much more loving to his granddaughter, Queen Elizabeth II.
