Eighteen Years' War

The Eighteen Years' War, 1529 to 1547, was a series of punctuated conflicts waged between the Holy Orenian Empire and the Grand Kingdom of Urguan and their various allies for dominance over the other - dwarves wishing to see the reunified human empire divided and split, and humans desiring to break the Urguanite realm and protect against further dwarven incursions and military interference. It was started by Grand King Midgor's ambition to reclaim the realm once conquered by Grand King Thorin Grandaxe nearly a century before, as well as reasserting dwarven dominance after the humiliating defeat in the Schism War. Grand King Midgor also envisioned a Urguanite superpower, wishing to divide the humans once again and place them under the dwarven yoke.

The dwarven nation held an invalued grudge against the Orenian nation, stemming from the First Human-Dwarven War in 1415, which led to off and on fighting between to the two nations for nearly a century and a half. Dwarves continued to maintain claim over the majority of human lands from Grand King Thorin's victory over William I after the previous Holy Orenian Emperor, Horen I, sailed to Aeldin to claim its imperial throne. When John I restored the imperial monarchy of Oren in 1526, a large mass of dwarven statesmen demanded the Urguanite government contain the Orenian Empire. In 1529, war was officially declared upon the Empire by the Grand Kingdom of Urguan. The first large scale battle would not be until 1536, the Battle of White Mountain, and fighting continued until the defeat of the First Rurikid Uprising of 1547.

The war would end between negotiations of the emperor's son, John II, and the dwarven ambassador Azaghal Doomforged in the Treaty of West Avar.

Prelude
John I had an alliance with Grand King Uldar Irongut (Who reigned from 1525-1529) and this alliance was a very rare détente between the two major world powers of the Holy Orenian Empire and the Grand Kingdom of Urguan. This alliance was exceptionally unpopular with many of the dwarven people, most of them had lived through a war with humans and hated the Holy Orenian Empire. This caused Uldar to be regarded as a puppet of the Empire, even though the weakened Oren (drained from the recent War of the Ducal Coalition) ostensibly wanted the dwarves to leave them alone.

Dwarven society was divided into two factions, pro-Uldar and anti-Uldar whom was the far greater number, the latter group was consisted of influential dwarves such as Hogarth Irongut, Belegar Ireheart, and Midgor Ireheart, whom operated off a pro-war platform.Eventually, after many assassination attempts and other attempted coups, Uldar was deposed of and the anti-Uldar party, which was anti-Oren and pro-war, prevailed in the early 1529's.

In the chaos of the throne’s vacancy, Emperor John, fearful of the election of a pro-war dwarven monarch, attempts to impose Uldar’s distant relative Gauldrim Irongut onto the throne of Urguan. The subterfuge fails, and John I issues the Statement of Solidarity (1529) declaring his public support for Gauldrim’s claim. In fear of the Holy Orenian Empire, this action serves to inadvertently galvanize the dwarven populace behind the pro-war candidate, Midgor Ireheart, who is elected Grand King of Urguan without real opposition.

Gauldrim is banished and expelled, as are any of Uldar’s former supporters.

This does not sit well with many of the Khalestinian denizens of the former Caliphate, chiefly the influential Kharadeens, who are virulently anti-Oren.

 * 1542:
 * Decimus Rovin resigns as ruler of Vandoria. The anti-Oren Qalasheen faction attempts to utilize this as a means by which to retake control of the country, rallying numerous provinces behind it.

Harold Winter, an avaricious nobleman whose family have been exiled from the Empire for generations, takes control as the ruler of Vandoria, officially joining the dwarves in their campaign.
 * The Imperial and allied forces continue their assault on the island’s dwarven settlements. On the 6th of the Grand Harvest, the Emperor and Augustus d’Amaury capture Kal’Valen, though this is largely due to the heroism of a single man-at-arms, Rael Acker.

Richard Revlis is believed slain in the battle.
 * 1547:
 * Internal pressures arise within Oren from scheming nobles, specifically those unwilling to pay the flat taxes required to maintain the war’s upkeep and those who are resentful of his autocratic style of rule.
