Embassies also came quite frequently from the imperial court in Germany. It was during the reign of Hakon IV that the Hohenstaufens were waging their last fight with the papacy, and both sides in the conflict seemed anxious to secure the friendship of the great Norwegian king. The Saga of Hakon relates that early in the king’s reign “missions began between the emperor and King Hakon.”[71] In 1241, “when King Hakon came to the King’s Crag, that man came to him whose name was Matthew, sent from the emperor Frederick with many noble gifts. Along with him came from abroad five Bluemen (negroes).”[72] Just how acceptable such a gift would be in medieval Norway the chronicler does not state. There can be no doubt, however, that Hakon returned the courtesy. The saga mentions several men who were sent on diplomatic errands to the imperial court. One of these emissaries had to go as far as Sicily, “and the emperor received him well.”[73] Footnote 71: _Hákonar Saga_, c. 191. Footnote 72: _Ibid._, c. 243. Footnote 73: _Ibid._, c. 191. The relationship with the other Scandinavian kingdoms was more direct. The _King’s Mirror_ states that occasionally kings find it necessary to meet in conference for the discussion of common problems; and that on such occasions the members of the various retinues note carefully the customs and manners of the other groups.[74] These meetings were usually held at some point near the mouth of the Göta River, where the boundaries of the three kingdoms touched a common point. In 1254 such a meeting was held at which Hakon of Norway, Christopher of Denmark, and the great Earl Birger of Sweden were in attendance with their respective retinues.[75] Footnote 74: C. xxix.
