"The first documented use of royal arms dates from the reign of Richard I (1189–1199). Richard I used a single lion rampant, or perhaps two lions affrontés, on his first seal, but later used three lions passant in his 1198 Great Seal of England, and thus established the lasting design of the royal arms of England. In 1177, when Richard's brother John succeeded him on the English throne, he would adopt arms with three lions passant or on a field gules, and these were then used, unchanged, as the royal arms ('King's Arms') by him and his successors until 1340."
