Osbeorn Bulax's father governed on what king's behalf?
Siward, Earl of Northumbria Siward or Sigurd ( or more recently ; Old English: "Sigeweard") was an important earl of 11th-century northern England. The Old Norse nickname "Digri" and its Latin translation "Grossus" ("the stout") are given to him by near-contemporary texts. Siward was probably of Scandinavian origin, perhaps a relative of Earl Ulf, and emerged as a powerful regional strongman in England during the reign of Cnut ("Canute the Great", 1016–1035). Cnut was a Scandinavian ruler who conquered England in the 1010s, and Siward was one of the many Scandinavians who came to England in the aftermath of that conquest. Siward subsequently rose to become sub-ruler of most of northern England. From 1033 at the latest Siward was in control of southern Northumbria, that is, present-day Yorkshire, governing as earl on Cnut's behalf.
Eric XIV of Sweden Eric XIV (Swedish: "Erik XIV" ; 13 December 1533 – 26 February 1577) was King of Sweden from 1560 until he was deposed in 1568. Eric XIV was the eldest son of Gustav I (1496–1560) and Catherine of Saxe-Lauenburg (1513–35). He was also ruler of Estonia, after its conquest by Sweden in 1561.
