AD 432

Saint Patrick

Traditional arrival of Patrick’s mission in Ireland

Patrick said his return began with a bundle of letters in a vision and a chorus from Ireland begging him to “walk again among us”.

A year Patrick never gives

The listing puts the arrival at 430. Patrick’s own Confessio says only that, many years after escaping captivity in Ireland, he returned to the Irish people to preach the gospel — it supplies no year, no landing place and no arrival narrative.

The traditional annalistic year is 432, not 430, and even that chronology is retrospective and disputed.

A Cambridge study summarises modern placement of the mission in the middle or late fifth century.

The letters in the vision

Patrick describes a vision in Britain in which a figure, Victoricus, brought letters from Ireland while voices begged him to “come and walk again among us”.

He presents that calling as the motive for his return, along with the gospel and God’s promises.

No reliable source preserves what he did on his first day ashore.

Palladius, the year before

Prosper of Aquitaine records that Pope Celestine sent Palladius as first bishop to Irish believers in 431 — a securely dated mission often confused or entwined with Patrick’s chronology.

The traditional 432 sits suspiciously close to it, and may have been constructed retrospectively.

Prosper’s notice refers to Irish people already believing in Christ, so Patrick did not arrive on an entirely non-Christian island.

Traditional date. Conventionally dated here; the research places it at ~0432.

What the sources leave uncertain

Patrick’s own surviving writings contain no securely datable event, including his missionary arrival.
The Irish annalistic tradition supplies 432, but that date is suspiciously close to the securely recorded dispatch of Palladius in 431 and may have been constructed retrospectively.
Modern scholarship ranges from an early-fifth-century Patrick to a mission in the middle or later fifth century. A Cambridge study summarizes modern placement in the middle or late fifth century.
The listed year 430 has no comparable traditional or contemporary support and may reflect loose rounding of the conventional 432 date.
