The House of Saxe-Coburg is a German royal family that originated in the 19th century. It was established in the small town of Coburg in Bavaria, and its members played significant roles in various European monarchies. The family is known for producing several notable monarchs, including Queen Victoria of the United Kingdom and King Leopold I of Belgium. The house became prominent through strategic marriages, which connected it to other royal families across Europe. In the United Kingdom, the name was changed to the House of Windsor during World War I due to anti-German sentiment, reflecting its lasting influence on British history.
