Excerpts from Books and Wikipedia
"The rebel leader was Henry Tudor. An exile living in Brittany, Henry's hereditary claim to the throne was tenuous, but he was the best candidate that Richard's opponents could find. . . . Henry Tudor took the throne as Henry VII, and founded a dynasty that reigned for 118 years until the death of Queen Elizabeth I in 1603." [Furtado: 1001 Days] "Richard III dies in battle, and Henry Tudor becomes king of England; last shift of Houses/kingship during the War of the Roses." [Wikipedia: Timeline of Middle Ages]
