Verse:Irta/Ireland

In Irta, Ireland grew into a major European power by the 9th century, controlling all of the British Isles, and at its greatest extent stretching as far as the Pyrenees, our Netherlands, and just to the west of our Paris. The Irish empire was bordered by an Old French-speaking region to the southeast, which was in turn bordered by Hivantish tribal lands in Eastern Europe and Scandinavia.

Some Irish territory remained on Continental Europe into the 17th century. Irish heavily influenced Crackfic Trician French, turning it into Hyperfrench with a quasi-Slavic phonology, and influenced Hivantish as well.

"What if Joseon was Irish-speaking and Catholic"

Early Middle Ages

The early medieval ard-rí was a figurehead over autonomous regional sub-kings. The ard-rí role became more centralized (unlike in our timeline) in response to a need for cooperation and centralization among the Irish-speaking tribes in response to external forces? However, Gaels still retained a clan-based system, like our Joseon; we could model some features of the Irish empire after Joseon

The bardic schools have one additional level which was required to become the Ardrí's poet, called the ardfhilidhe (ardfhilí)?

The ardrí was still elected by tanistry

Some religious text translations should use "Ardrí" rather than "Rí" for God

Where should the capital be?

Catholicism was the state religion but Jews were tolerated to an extent

The Taking of Britain

The Brythonic assimilate to the Gaelic speakers, except those who went to the mainland who became Galoyseg speakers; some Irta Irish surnames should be Brythonic

Late Middle Ages

"What if Joseon was Irish-speaking and Catholic"

Expulsion of Jews from Continental Ireland (12th-13th c.)

Middle Irish-speaking Tsarfati Jews migrated to Central and Eastern Europe, and their language became Ăn Yidiș

Imperial exam system

Much like the Joseon one

Post-Remonition

During the 16th and the 17th centuries, the two Remonitions occurred and Ireland lost all of its mainland territory (to the Remonitionists and the Hivantish) in the ensuing religious wars by the 17th century. Ireland could still become a colonial power, explaining the presence of Irish in the Americas and the mainly Catholic Anatolian region of Irta's Arab world --- or maybe Irtan Maltese? (Formal Irta Anatolian Arabic is syntactically Irishy)
