 Baldwin asserted his independence by mediating disputes in Antioch and Tripoli, and gained the support of the Ibelin brothers when they began to oppose Manasses' growing power, thanks to his marriage to their widowed mother Helvis of Ramla.In 1153 Baldwin had himself crowned as sole ruler, and a compromise was reached by which the kingdom was divided in two, with Baldwin taking Acre and Tyre in the north and Melisende remaining in control of Jerusalem and the cities of the south.Baldwin was able to replace Manasses with one of his own supporters, Humphrey II of Toron.
