The House of Gallagán was an Ascalene dynasty that ruled as Princes of Ascalzar from its founding in 1270 to 1456. The princely house was founded by Padrig Gallauhánn, a Gelonian knight in the service of the King of Adrianople, with whom he crusaded in northern Scipia. His son, Yann Gallauhánn, would be crowned the first Prince of Ascalzar as John I.
The House of Gallagán would go extinct in the male-line in 1456 with the death of Hieronymus II, after which the principality became a dual monarchy under the headship of the Sydalene Crown and the Pope of Fabria. Today, the house has one extant cadet branch the House of Matamoros-Gallagán, agnatically descended from the illegitimate son of John I, Sebastian the Moor-slayer, and cognatically descended of the dynasty via the counts of Gallagán. This house remains a strong political force in Ascalzar, having produced over forty First Counsellors.
