, Trier made several attempts to achieve autonomy from the Archbishopric of Trier, but was ultimately unsuccessful. In 1212, the city received a charter from Emperor Otto IV, which was confirmed by Conrad IV. In 1309, however, it was forced to once again recognise the authority of the Archbishop, who was at that time the imposing Baldwin of Luxembourg, son of the Count of Luxemburg. Elected in 1307 when he was only 22 years old, Baldwin was the most important Archbishop and Prince-Elector of Trier in the Middle Ages. He was the brother of the German King and Emperor Henry VII and his grandnephew Charles would later become German King and Emperor as Charles IV. He used his family connections to add considerable territories to the Electorate of Trier and is also known to have built many castles in the region. When he died in 1354, Trier was a prospering city. The status of Trier as an archbishopric city was confirmed in 1364 by Emperor Charles IV and by the Reichskammergericht; the city's dream of self-rule came definitively to an end in 1583. Until the demise of the old empire, Trier remained the capital of the electoral Archbishopric of Trier, although not the residence of its head of state, the Prince-Elector. At its head was a court of lay assessors, which was expanded in 1443 by Archbishop
