Konrad III the Sendlinger († 1322) was the 31st bishop of Freising in the years 1314 to 1322.

Konrad came from a wealthy and respected Munich patrician family Sentlinger. He was chaplain and
Secretary to the Freising bishop Emicho Wildgraf von Wittelsbach († 1311) and became Freising canon under his predecessor Gottfried von Hexenagger. He was the first Freising bishop to earn a doctorate (in canon law) at a university (probably Bologna).[1]

He was elected Bishop of Freising in 1314. Like his predecessor Gottfried von Hexenagger, Konrad skilfully managed to manoeuvre between Louis the Bavarian and Duke Frederick the Fair in the struggle for supremacy in the Holy Roman Empire of the German Nation, favouring neither side but securing advantages for himself with both parties to the conflict. Thus Conrad attempted to mediate between Louis and Frederick in 1315, but was unsuccessful.[2]

In 1315/1316, during the reign of Konrad III, the Konradinische Matrikel was compiled, a medieval land register which listed the possessions of all prince-bishop’s estates with their revenues and was at the same time a precise diocesan description in which all churches, chapels, monasteries and cemeteries were enumerated.[3] In this register there is also for the first time a coloured illustration of the high diocesan coat of arms, the “Freisinger Mohr”. It had been used as a seal for the diocese since the time of Bishop Emicho.

In 1319, Konrad III acquired the county of Ismaning (also: county on the Yserrain) from Ludwig the Bavarian and was thus able to decisively enlarge the high diocese; after all, a closed stretch of land on the east side of the Isar from Freising to the gates of Munich now belonged to the high diocese. In this purchase contract, the absolute sovereignty of Freising was expressly confirmed.[4]

From 1319 to 1321, under his rule, the new St. John’s Church on the Freising Cathedral Hill was built in the classical early Gothic style; on June 8, 1319, Konrad endowed the associated collegiate monastery of St. John, which lasted until 1803.
Konrad probably died at Freising on 11 or 12 April (around Easter) 1322. All Freising chronicles report that he was poisoned, allegedly by one of his servants. He was buried in St. John’s Church next to the cathedral.[5]
