Rebellion in Polenya.
Revolution
Ongoing occupation of Polenya by Lanoirenn leads to open rebellion.
Despite Polenya being subjugated by Lanoirenn during the Second Polenya War, the prolanoirenn kings installed in Polenya were extremely unpopular.
With Lanoirenn heavily invested in the ongoing Fourty Years War, the local regime underwent a period of weakening that culminated in proimperial rebellion that quickly spread like a wildfire throughout the eastern elven states.
