Description

Theodosius II (Latin: Flavius Theodosius Iunior Augustus; Greek: Θεοδόσιος Β'), commonly surnamed Theodosius the Younger, or Theodosius the Calligrapher, was Eastern Roman Emperor from 408 to 450 (from January 402 to 1 May 408 with Arcadius, then 1 May 408 to 28 July 450 alone, with Anthemius and later Pulcheria acting as regent from 408 to 416).

He is mostly known for promulgating the Theodosian law code, and for the construction of the Theodosian Walls of Constantinople. He also presided over the outbreak of two great christological controversies, Nestorianism and Eutychianism.
