Magnus IV of Sweden
Bo Jonsson (Grip) (early 1330s – 20 August 1386) was head of the royal council and marshal under the regency of Magnus IV of Sweden. Also in the council was his friend and colleague, Karl Ulfsson av Ulvåsa, eldest son of Saint Birgitta. From 1369, during Albert of Sweden’s reign, he was "Officialis Generalis" (the king's highest official) and from 1371 Lord High Steward ("drots" in Swedish).
