Dagobert of Pisa

Dagobert (or Daibert or Daimbert) (died 1105) was the first Archbishop of Pisa and the second Latin Patriarch of Jerusalem after the city was captured in the First Crusade.

Little is known of Dagobert's early life, but he is thought to have originally been ordained by Wezilo,Archbishop of Mainz 1084-88, a leading supporter of the emperor in the Investiture Controversy and of the Antipope Clement III. In 1085, Wezilo was excommunicated for simony by the pro-papal synod of Quedlinburg. Dagobert's own name places his origin in Lombardy/Emilia, site of some staunchly imperial cities.

By the late 1080s Dagobert had changed sides, becoming close to Countess Matilda of Tuscany, one of the papacy's staunchest supporters. Pope Urban II cancelled Dagobert's irregular ordination and replaced it with a canonical one, and in 1088 made him Bishop of Pisa. Initially, the appointment of a man with such a controversial past attracted hostility. Peter, Bishop of Pistoia, protested to the pope, and the cathedral chapter opposed it, but Urban's continued support allowed Dagobert to establish his authority. He played an active role in Pisa's civic life, for example joining with other notables in 1090 to regulate the maximum height of houses, and by 1092 the clergy were signing his documents. He seems to have become a well-respected figure in Pisa's political and economic life, adopting a practical approach to the problems he faced both in Pisa and later in his career. He remained close to Urban and Matilda, and in 1092 Urban raised the see to an archbishopric on Matilda's recommendation.

Dagobert spent Christmas of 1094 with Pope Urban, and then accompanied him on his pastoral tour of Italy and France, including the Council of Piacenza, held to reassert the pope's authority after the Investiture Controversy, and the Council of Clermont, at which the pope launched the First Crusade. Dagobert then returned to Pisa to preach the crusade, and received enthusiastic support. In 1098 Urban appointed him legate at the court of King Alfonso VI of Castile, and he proved competent in his organisation of the church in the lands recently conquered from the Moors, although he was rumoured to have kept for himself some treasure sent by King Alfonso to the Pope.
