285 - 305 ad
Diocletian reorganized the administration of the Empire, breaking
the provinces into smaller units grouped into twelve dioceses. Governors
lost their
military authority, military commands became independent of provincial boundaries,
the Senate lost most of its privileges, and Italy became subject to full
taxation. Fiscal
measures included monetary reform and a price fixing edict. The
Tetrarchy is also remembered
for severe persecutions of Christians [303- 313]. |
