 After two and a half years, Charles himself came to Kaumberg to receive Svatopluk as his vassal and accept promises of peace.An actual agreement was not reached between the Moravians and Arnulf until late 885.The war is generally seen as having greatly augmented the power of Svatopluk I and strengthened his bonds to the Empire, as illustrating Charles diminished authority over his vassals and his inability to control their fidelity, and as rupturing the relationship between uncle and nephew and thus ruining the chances of Arnulf becoming Charles' heir or even receiving imperial largesse.
