An idea arose in Victorian Britain that the royal dynasty and throne of David, King of Israel and Judah c. 1000 BC, far from dying out as the result of successive Assyrian and Babylonian invasions, has continued in an unbroken line that leads directly to the British Throne. Following this royal line through Irish, Argyllshire, Scottish and English history, Lewis finds that our Queen Elizabeth II is descended from the Judean princess who came to the shores of Ireland. The end of the book suggests that the genealogical descent includes a sign of Christ's forthcoming return, and for this reason the British monarchy and throne could be approaching a new era.
