Crusades

The Crusades were a series of conflicts fought in and around Palestine in at least the 12th and 13th centuries. The principal aim of the crusades was for European Christian forces to retake control of Jerusalem and the Holy Land from Muslim occupation, as well as campaigns against other races and religions. Monarchs, nobles and commoners, all involved took oaths to uphold the principles of the crusade in exchange for indulgences against past sins. (TV: The Crusade, The King's Demons)

When the Doctor's fifth incarnation arrived in England on 4 March 1215, he determined that an impostor had taken the place of King John, since the real King was known to be in London taking the Crusader's Oath on that very day. The Doctor's suspicions were confirmed when he met Sir Geoffrey de Lacy, who had arrived from London and was perplexed as to how the King could be in the capital yet in the countryside at the same time.
