560 Synod of Brefi

The Synod of Brefi was a church council held at Llanddewi Brefi in Ceredigion and was followed by the Synod of Victory at Caerleon around 569. The synod was apparently called in order to condemn the heretical teachings of Pelagius, although this is far from certain. It was an important milestone in the rise of Saint David. Saint David (Welsh - Dewi Sant) was a Welsh bishop of Menevia during the 6th century. He was later regarded as a saint and is the patron saint of Wales.

450 Kingdom of Ceredigion

The Kingdom of Ceredigion was one of several Welsh kingdoms that emerged in 5th-century post-Roman Britain. Its area corresponded roughly to that of the modern county of Ceredigion. The kingdom's hilly geography made it difficult for foreign invaders to conquer. Ceredigion transparently means "the people of Ceredig". Ceredig ap Cunedda (c. 420 - 453), king of Ceredigion, may have been born c. 420 in the Brythonic kingdom of Manaw Gododdin (modern Lothian in Scotland). He is one of the sons of Cunedda, grandfather of Saint David.

383 Magnus Maximus

Magnus Maximus (Flavius Magnus Maximus, Welsh - Macsen Wledig, ca. 335 - 388) was Western Roman Emperor from 383 to 388. The earliest Welsh genealogies give Maximus the role of founding father of the dynasties of several medieval Welsh kingdoms, including those of Powys and Gwent. He is given as the ancestor of a Welsh king on the Pillar of Eliseg, erected nearly 500 years after he left Britain, and he figures in lists of the Fifteen Tribes of Wales.

212 Constitutio Antoniniana

The Roman conquest of Wales began in AD 48 and took 30 years to complete. While Romanisation was far from complete, the upper classes of Wales began to consider themselves Roman, particularly after the ruling of 212. The Constitutio Antoniniana (also called the Edict of Caracalla or the Antonine Constitution) was an edict issued in 212, by the Roman Emperor Caracalla declaring that all free men in the Roman Empire were to be given theoretical Roman citizenship and that all free women in the Empire were to be given the same rights as Roman women.
