Victorian writer John Henry Haaren says in "Famous Men of the Middle Ages" "The battle of Tours or Poitiers as it should be called is regarded as one of the decisive battles of the world. It decided that Christians and not Muslims should be the ruling power in Europe." Bernard Grun delivers this assessment in his "Timetables of History", reissued in 2004: "In 732 Charles Martel's victory over the Arabs at the Battle of Tours stems the tide of their westward advance."
