The chief primary source for the War is
Philip of Novara's
The Wars of Frederick II Against the Ibelins, which is a highly partisan account favouring the Ibelins. Philip was an active participant in and eyewitness of many of the events he describes. In the 1240s he was handsomely rewarded in money and fiefs by Alice. His
Wars is generally trusted but is contained in a later compilation called
Les gestes des Chiprois, and it is sometimes difficult to determine if a detail was amended by the compiler. His account, written contemporaneously with events, only covers 1228–1233, 1236, and 1241–1242. He wrote the last part of his account between 1242 and 1247, adding interpolations until as late as 1258. It is Philip that gives the name
Longuebars (Lombards) to the imperialists. The
Venetian baili
Marsilio Zorzi, who arrived in Acre shortly before Alice's election as regent, wrote a report of conditions and recent events in the Levant for his masters in Venice. It is preserved in a manuscript of 1246 and in the fourteenth-century
Liber Albus, but is a less precise, though more contemporaneous, account than Philip's.
Richard of San Germano presents a few details with regards to the beginning of Conrad's rule and the end of Frederick's regency that cannot be found elsewhere. According to him,
Tommaso of Aquino, Count of
Acerra, left for the Holy Land in June 1242 in connection with Conrad's assumption of power to be the King's representative in the East. He also mentions that
Raymond VII of Toulouse met the Emperor at
Melfi in September 1242 and intervened on behalf of the defeated Filangieri. ==Notes==
