Source-derived summary

Duke of Ireland is a title that was created in 1386 for Robert de Vere, 9th Earl of Oxford (1362–1392), the favourite of King Richard II of England, who had previously been created Marquess of Dublin. Both were peerages for one life only. At this time, only the Pale of Ireland (the Lordship of Ireland) was under English control. Despite its name, the Dukedom of Ireland is generally considered to have been one in the Peerage of England, and is the first time that a ducal title was created for someone who was not a close relative of the king.

The arms with three crowns that were granted to Robert as an augmentation to his arms in 1386 continued to be used for nearly a century as the arms of the Lordship of Ireland.

Robert fell from favour shortly after receiving the title, resulted in forfeiture of the first creation in 1388.

Editorial summary

Editorial reviewA practical starting point whose main value is the path it opens into stronger specialist and primary sources. The current lead gives the account dated anchors—1386, 1362, 1392, 1388—that can be checked directly. The selected authority fields contribute no independent date.

Editorial analysis

Why this record matters

The subject matters to the general reference register because the source frames it as open-knowledge reference entry. Its deeper value depends on whether names, dates, institutions and citations support that framing.

Evidence profile

Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Sep 7, 2026. The linked authority identifier is Q2097129. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1386, 1362, 1392 and 1388.

Critical limits

Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Use the entry as an orientation point, then follow its citations and revision history. Names, dates and institutional relationships should be checked against the original record.
