In the castle the visitor may notice a list of all the Emperors--some thirty odd, all told--who have stayed there--a list that should now include the reigning Emperor. We find that Henry IV. frequently honored Nuremberg with his presence. This is that Henry IV., whose scene at Canossa with the Pope--Kaiser of the Holy Roman Empire waiting three days in the snow to kiss the foot of excommunicative Gregory--has imprest itself on all memories. His last visit to Nuremberg was a sad one. His son rebelled against him, and the old king stopt at Nuremberg to collect his forces. In the war between father and son Nuremberg was loyal, and took the part of Henry IV. It was no nominal part, for in 1105 she had to stand a siege from the young Henry. For two months the town was held by the burghers and the castle by the Prefect Conrad. At the end of that time orders came from the old Kaiser that the town was to surrender. He had given up the struggle, and his undutiful son succeeded as Henry V. to the Holy Roman Empire, and Nuremberg with it. The mention of this siege gives us an indication of the growth of the town. The fact of the siege and the words of the chronicler, "The townsmen (oppidani) gave up the town under treaty," seem to point to the conclusion that Nuremberg was now no longer a mere fort (castrum), but that walls had sprung up round the busy mart and the shrine of St. Sebald, and that by this time Nuremberg had risen to the dignity of a "Stadt" or city state. Presently, indeed, we find her rejoicing in the title of "Civitas" (state). The place, it is clear, was already of considerable military importance or it would not have been worth while to invest it. The growing volume of trade is further illustrated by a charter of Henry V. (1112) giving to the citizens of Worms customs' immunity in various places subject to him, among which Frankfort, Goslar and Nuremberg are named as royal towns ("oppida regis").
