Baldwin of Ibelin year, the king betrothed his younger half-sister Isabella of Jerusalem, Balian's stepdaughter, to Humphrey IV of Toron, to further reduce the Ibelins' influence. In 1183 he supported Raymond against Guy, who was by now regent for the ailing Baldwin IV. Lord Baldwin was among the barons who advised the king to crown Sibylla's son Baldwin V in 1183, while Baldwin IV was still alive; this was an attempt to prevent Guy from succeeding as king. Baldwin V became sole king while still a child in 1185, and when the young king died in 1186, Sibylla was crowned queen with Guy
Baldwin II, Margrave of Flanders Baldwin II, Margrave of Flanders Baldwin II ( 865 – 10 September 918) was the second margrave (or count) of Flanders, ruling from 879 to 918. He was nicknamed the Bald ("Calvus") after his maternal grandfather, King Charles the Bald. Baldwin II was born around 865 to Baldwin I of Flanders and Judith of Flanders, the great-granddaughter of Charlemagne. The early years of Baldwin's rule were marked by a series of devastating Viking raids into Flanders. By 883 CE, he was forced to move north to Pagus Flandransis, which became the territory most closely associated with the Counts of Flanders.
