terms of the reconciliation accorded in 1216 lasted less than a year. The proud and ambitious attitude of Archbishop Kietlicz effectively discouraged his supporters and stopped his meddling in Piast Dukes affairs. His importance suffered a further decline after the defeat of the policies of Pope Honorius III. In 1217 an unexpected treaty was concluded between the previous antagonists Leszek I the White and Władysław Spindleshanks, under which if one or both rulers died without male issue, the other could inherit all his domains. This agreement clearly affected the interests of the Duke of Kalisz Władysław Odonic, Spindleshanks' nearest male relative. Deposition of Władysław Odonic In the same year the Duke of Greater Poland took advantage from the benevolent neutrality of Henry I the Bearded and finally decided to resolve the conflict with Odonic and took the district of his nephew, forcing him to flee the country. The formal alliance between Spindleshanks and Henry I the Bearded (similar to the previous agreement with Leszek I the White) took place at the end of 1217 or early 1218, during an assembly in Sądowel, through the mediation of the Bishops Paweł II of Poznań and Wawrzyniec of Lubusz. For unknown reasons, the content of the arrangements was beneficial only to the Duke of Greater Poland, who not only received the permission to retain Odonic's district (which included parts of Kalisz, who under the agreement of 1206, was returned to Silesia), but also obtain the district of Lubusz (captured in 1209 by the Margrave of Lusatia Conrad II but recovered by Henry I the Bearded one year later) during his lifetime. The agreement of Sądowel was ratified by a special papal bull issued on 9 May 1218, which further broke down the power of Archbishop Kietlicz. The first test of the Triumvirate (Władysław III Spindleshanks, Henry I the Bearded and Leszek I the White) was the death in 1219 of Archbishop Henry Kietlicz and the common choice for the post of Archbishop, the chancellor Wincenty z Niałka, one of Spindleshanks' closest associates. Return of Władysław Odonic Despite the many benefits of Władysław Spindleshanks received in the congress of Sądowel he didn't participate in a national campaign against the pagan Prussians. The reason for this were the actions of his nephew Władysław Odonic, who, thanks to the hospitality and collaboration of Swantopolk II of Pomerania (probably Odonic's brother-in-law) began his struggle against the authority
