 Dublin was besieged by the victorious Máel Sechnaill, who forced it to surrender slaves and valuables, as well as give up all its prior claims to Uí Néill-held territory.In the following decade, Dublin was more or less under the control of Máel Sechnaill and the southern Uí Néill.The Battle of Tara is regarded as a far more decisive defeat for the Norse of Dublin than the later, and much more famous, Battle of Clontarf.
