 Nicholas negotiated a peaceful settlement, crowned Simeon emperor of the Bulgarians in a makeshift ceremony outside Constantinople, and arranged for the marriage of Simeon's daughter to Constantine VII.This unpopular concession undermined his position, and by March 914, with the support of the "magistros" John Eladas, Zoe Karbonopsina overthrew Nicholas and replaced him as foremost regent.She revoked the agreement with Simeon, prompting the renewal of hostilities with Bulgaria.
