In any case, both parties eventually reached a settlement, restricting Seuthes to the interior and Lysimachus to the coastal regions of the Aegean and Black Sea. There is no evidence for Lysimachus vassalizing Seuthes. Thrace north of the Rhodopes probably remained outside of Lysimachus' reach, as he may have regarded its pacification not worth the money and manpower. In 313 Seuthes allied with revolting Greek towns on the western shore of the Black Sea, but Lysimachus defeated this alliance. It is possible that to guarantee the peace between the two opponents, Seuthes married a daughter of Lysimachus named Berenice. Afterwards, there is no evidence for another confrontation between the two.
