Germanic Saxon raids on Roman Britain continued.  The Picts of Scotland and the Scots from the west also made raids on Roman Britain.  In India, Samudragupta of Magadha extended his kingdom east to Assam and west to the Punjab.  In Dacia, the Sarmatians were attacked by Goths and other Germanic tribes.  Constantine I of Rome helped them defeat these enemies but then the Sarmatians began to attack Roman territories.  Constantine then had the Goths crush the Sarmatians. Around this time, the Goths began to receive subsidies from Rome for military service (foederati).  Also at this time, the Visigoths were soundly defeated in the area of Yugoslavia and Bulgaria.  Following this, they began to make raids into the Roman Empire.  After the death of Constantine I, his empire was divided between three rulers-Constantine II in the west, Constantius II in the east and Constans in Italy and the south.  Immediately, Constantius II became engaged in constant warfare with Shapur II of Persia for control of Armenia and Mesopotamia.  In 340, Constantine II invaded Italy, was killed, and Constans took the western empire.
