Nordmontaine War

The Nordmontaine War was a conflict between the central authorities of the Holy Levantine Empire and the Kingdom of Angla as a consequence of the Protestant Reformation. Emperor Conchobar III's vigorous prosecution of the counter-reformation lead to consistent disagreement and disputes between the Emperor and the Protestant princes of the Empire, especially those in the Kingdom of Dericania. By 1543 the Emperor began to use the Imperial Army to enforce the restoration of Church property throughout the Empire, with Angla being the largest appropriator of Church lands. The Emperor marched into Angla in 1543, beginning the Nordmontaine War. By 1554, King Godwin III was killed by the Imperial Army at the Battle of Highmarch, ending the war and shattering the Kingdom of Angla. The total dissolution of such a powerful Protestant realm lead to Urcea and Gassavelia forming the Protestant Union in the same year along with smaller princes within the Empire, especially within Dericania.

Legacy
The Nordmontaine War resulted in the complete destruction of a united Ænglish state, dividing the Ænglish people for nearly three centuries until the establishment of Anglei in 1884. Following its partition, the Imperial Diet adopted a measure officially prohibiting any Ænglish polity from being created. This measure, known as the "Shameful Prohibition" in Anglei, was repealed by the Concordat of Donnebourg.
