It is not certain whether Conrad was a member of the patrician family named von Vechta, living as successful merchants in Bremen, where family members also held positions in the city government, or if Conrad was born in Vechta and therefore epithetised von Vechta in German. However, his brother Konstantin von Vechta held a canonicate at Bremen Cathedral as cathedral provost, presiding the cathedral chapter. This rather substantiates a patrician background, because Bremian canonicates were usually provided for members of patrician families of Bremen or of noble families of the Bremian knightage. Conrad was definitely no member of the comital family of Vechta, which used to be called after its castle Counts of Ravensberg. Conrad strove for a clerical career. He sided already early with Wenceslaus, King of the Romans, ruling the Holy Roman Empire since 1376, on whose instigation Conrad was provided with a number of prebends. As many North Germans used to study in Prague, Conrad's siding with Wenceslaus, who was simultaneously ruling as King of Bohemia since 1378, may indicate that Conrad had done so too. In 1395 Wenceslaus failed to get Conrad invested as bishop of Verden, whereas Dietrich of Nieheim prevailed. Conrad had earlier been provost of Lüne Nunnery and was then promoted to canon of the Collegiate Church of St. Blaise in Brunswick.
Provided bishop of Verden
In 1400 Pope Boniface IX, on Wenceslaus' instigation, deposed Conrad's provided predecessor Conrad of Soltau, who had so far only been provided bishop of Verden in 1399, but not invested, and provided instead Conrad of Vechta not before 1 May, however, also lacking investiture. Conrad titled himself bishop elect of Verden until 1407. Lacking the elective mandate of the cathedral chapter in Verden upon Aller, it did not recognise his episcopate. However, the pope soon changed his mind again, when the other prince-electors had deposed Wenceslaus as ruler of the Empire in 1400 and replaced him by King Rupert, who in May 1401 had accepted the deposed Conrad of Soltau, a native of the Prince-Bishopric of Verden, as legitimate and invested him with the princely regalia as prince-bishop. Boniface IX thus also confirmed Conrad of Soltau as canonical bishop of Verden in autumn 1402.
