10. Following the example of our ancestor, the emperor Frederick of blessed memory, we forbid any of our officials to claim jurisdiction in the matter of tolls, mints, or other rights, in any of the cities of the ecclesiastical princes, except during the time of the public diet and eight days before and eight days after. During that time the officials of the emperor shall exercise jurisdiction in accordance with the customs of the city and the laws established by its prince. If we come into any of their cities at any other time, we will not exercise any rights in it, but the authority of the prince or the lord of the city shall continue unimpaired. 11. Finally, since the acts of men are wont to sink into oblivion through the lapse of time, we hereby decree that these benefits and privileges shall be perpetually granted to the churches, and that our successors shall preserve them and enforce them on behalf of the church.... 137. Decision of the Diet Concerning the Granting of new Tolls and Mints, 1220. M. G. LL. folio, II, p. 237; Böhmer-Ficker, no. 1118; Doeberl, V, p. 150. The ecclesiastical princes promptly demanded that the emperor's concessions to them (no. 136) be put into force. To illustrate the effect of his grant, we give two documents, one in response to complaints about some new tolls established by the count of Gelder, the other to the patriarch of Aquileia who had presented a long list of grievances for redress. Frederick revoked the charter which he had given the count of Gelder and gave the patriarch a charter confirming him in the possession of many regalian rights (no. 138). This latter document shows that the patriarch was in the possession of a high degree of sovereignty. It also throws light on the movement in the cities, which were throwing off the rule of their lords and establishing local self-government (see section X). Frederick, etc. We wish all to know that while we were holding a diet at Frankfort the following decision was rendered with the consent of the princes, namely: That we have not the right to empower anyone to establish new tolls or mints to the damage or disadvantage of another. Since we have heard many complaints about the tolls and mint which the count of Gelder has established, as he says, with our permission, we inform you all that we do not grant him the permission for these tolls and this mint. We forbid him to interfere in any way with the tolls at Arnheim, or Oesterbeke, or Lobith, or in any other place on the Rhine, or with any mint. We do this regardless of the fact that he says he has our permission, and regardless of any letters, from us or any of our predecessors, which he may have. 138. Frederick II Gives a Charter to the Patriarch of Aquileia, 1220. Böhmer-Ficker, no. 1252; Doeberl, V, pp. 150 ff. See introduction to no. 137.
