King Alfred the Great. (871-899) House of Wessex. Queen Elizabeth II's 32nd great-grandfather! Succeeded his brother Aethelred. Defended England against Danish invasion and founded the first English navy. He encouraged the translation of scholarly works from Latin (some he translated himself) and promoted the development of the Anglo-Saxon Chronicle. This ensured his deeds were recorded in history. We know more about him than any other Anglo Saxon King. Succeeded by son, Edward.
