when did the british royal house change its name from saxe-coburg and gotha to windsor?
1917
in march 1917, the "landtag" of coburg excluded members of the ducal family from the succession if their country was hostile to (i.e. at war with) germany. in july 1917, still unaware of the change in law at coburg, in an effort to distance his dynasty from its german origins, george v changed the name of the british royal house from the house of saxe-coburg and gotha to the house of windsor as an anti-german gesture. that year, the uk parliament passed the titles deprivation act which empowered the privy council to investigate "any persons enjoying any dignity or title as a peer or british prince who have, during the present war, borne arms against his majesty or his allies, or who have adhered to his majesty's enemies."

palmerston rejected this understanding which had been made with his predecessor, and instead revived the suggestion of prince leopold of saxe-coburg and gotha as a suitor. the house of saxe-coburg and gotha was closely linked to the british royal house; queen victoria's mother was born princess victoria of saxe-coburg and gotha and her husband since 1840 was prince albert of saxe-coburg and gotha. the british had backed the candidature of another prince leopold of saxe-coburg and gotha as king of belgium in 1830, and although he had married louis-philippe's eldest daughter, the french were confronted with the possibility of facing a britain-aligned dynasty on both of france's northern and southern borders if palmerston succeeded in his enterprise. guizot therefore determined to adamantly oppose any coburg marriages.
