Second Griffon-Pony War

The Second Griffon-Pony War (also the Second War) was a war that occurred in the Griffon Kingdom and lasted from May to August of the Solar Era Year 1000. It involved the two nations of Equestria and the Griffon Kingdom, and was the first war either country had endured in hundreds of years. The war was sparked by King Alaric Dawnbreaker's desire to reclaim the eastern coastal lands of Equestria, lands that had formerly belonged to the Griffon Kingdom up until the First Griffon-Pony War. The griffons were caught in active espionage on Equestria, which prompted the Equestrians to invade the griffons as a matter of self preservation when their intentions came to light. The griffons fought a guerrilla war against the Equestrians in the region.
As the war wore on, the Equestrians systematically captured and defeated griffon strongholds and forces. The griffons relied on ambush-style attacks and knowledge of the terrain to whittle down Equestrian numbers while the Equestrians maintained a steady pressure on the griffon lines with their vast numbers and advanced military technology.
Despite attempts at diplomatic resolutions, the war proceeded until a military victory was achieved with the capture of Asgard. Alaric was ultimately dethroned and ousted from the Griffon Kingdom. In the aftermath of the war, the griffons adopted a parliamentary government that soon crumbled, leaving the nation in a state of destabilization and conflict.
