Welsh history on the islands that would come to form De Mor Tir...
The idea of independence from the Haruwin came in the 1880s following a decidedly conflict-based period of time in Atlantia. A'Asabism had made its violent struggles and imperialism continued to make steady advances, but during this time, De Mor Tir had a great advantage of leadership.
Starting in 1874, a noted Brythonic Jew, Jwda Gof Arian, proposed the idea of a Jewish homeland near Jerusalem. Arian would become a powerful figure in De Mor Tir, as would Pryce Maldwyn Bowen, a Brythonic culturalist.
Both men sought the independence of De Mor Tir, and so created the Plaidd Fawr Brython in 1880, dedicated to a Brythonic culture preserved in De Mor Tir.
On August 10, 1881, the Datganiad Anibyniath was signed, declaring Tirwrian independence. Folant Pugh-Stuart, a distant descendant of Arthur III, was crowned the King of De Mor Tir and King of Fawr Brython.
