第6回十字軍
The Sixth Crusade came to an end with the so-called Treaty of Jaffa and Tell Ajul. These were in fact two different treaties, the first being the one signed at Tell Ajul by the competing Ayyubid rulers of Egypt, Syria and various smaller principalities. This treaty settled their territorial disputes and left Sultan Al-Kamil of Egypt in a very powerful position. The follow-up treaty was signed at Jaffa by Al-Kamil and the leader of the Sixth Crusade, Emperor Frederick II, thus removing the threat posed to Al-Kamil by the European armies.
