244 CE to 387 CE
The Roman Empire is plagued by internal strife and economic crisis in the third century CE. Two ethnic Illyrian emperors, both born in Southeastern Europe, take decisive steps to prolong the empire’s survival.
- Emperor Diocletian, born in Dalmatia, implements strong central control, establishes a bureaucratic system, and abolishes the last remnants of Roman republican institutions. In an effort to strengthen loyalty to the state, he launches a persecution of Christians, seeking to reduce their allegiance to the church.
- Emperor Constantine, born near Naissus (modern Niš, Serbia), reunites the empire after years of turmoil, introduces dynastic succession, and in 330 CE, founds a new capital at Byzantium, later named Constantinople. He also legalizes Christianity, marking a pivotal shift in Roman religious policy.
