Moesia included most of the territory of modern-day Western Serbia.
As a frontier province, Moesia was strengthened by stations and fortresses erected along the southern bank of the Danube, and a wall was built from Axiopolis to Tomi as a protection against the Scythians and Sarmatians
After 238 AD, Moesia was frequently invaded or raided by the Dacian Carpi, and the East Germanic tribe of the Goths, who invaded Moesia in 250
