- 4th century
As a means of recording the passage of
time , the 4th century (per theJulian calendar andAnno Domini /Common era ) was thatcentury which lasted from301 to400 .Overview
In the West, the early part of the century was shaped by
Constantine I , who became the first Roman emperor to convert toChristianity . Gaining sole reign of the empire, he is also noted for re-establishing a single imperial capital, choosing the site of ancientByzantium in 330 (over of the current capitals, which had effectively been changed byDiocletian 's reforms toMilan in the West, andNicomedia in the East) to build the city soon called Nova Roma (New Rome); it was later renamedConstantinople in his honor.The last emperor to control both the eastern and western halves of the empire was
Theodosius I . As the century progressed after his death it became increasingly apparent that the empire had changed in many ways since the time ofAugustus . The two emperor system originally established by Diocletian in the previous century fell into regular practice, and the east continued to grow in importance as a centre of trade and imperial power, whileRome itself diminished greatly in importance due to its location far from potential trouble spots, like Central Europe and the East. Late in the century Christianity became the official state religion, and the empire's old pagan culture began to disappear. General Prosperity was felt throughout this period, but recurring invasions by Germanic tribes plagued the empire from AD376 onward. These early invasions marked the beginning of the end for theWestern Roman Empire .According to archaeologists, sufficient archaeological correlates of state-level societies coalesced in the 4th century to show the existence of the Three Kingdoms (AD 300/400-668) of
Baekje ,Goguryeo , andSilla .Events
