The Alliance-Horde War[1] was a conflict fought between the New Horde and the Grand Alliance. Its exact beginning is uncertain but its end appears to have officially been in the Siege of Orgrimmar, with the removal from power of Garrosh Hellscream, though as with its status before it started, skirmishes and fighting continued amongst various factions of the Alliance and Horde following the end of the siege. Largely a series of brushfire conflicts, minor skirmishes, territorial disputes and interrupted periods of more open warfare, it consisted of numerous campaigns and internal conflicts.

Major Fronts of the War

War in the Eastern Kingdoms

A major front of the war, the Alliance-Horde conflict in the Eastern Kingdoms took place mostly within the subcontinent of Lordaeron which is wildly recognized as having commenced with the Battle for the Undercity in 29 L.C., though many consider the Invasion of Gilneas of 30 L.C. to be the official commencing point of the conflict. While most of the fighting had been contained in the north, various areas of the south have also seen bloodshed.

Notable battles and events

War in Kalimdor

Another major front, the conflics in Kalimdor were mostly fought in the northernmost territories, with the Barrens, Stonetalon and Ashenvale seeing the majority of the fighting. Notably, Kalimdor was the site of the last battle of the war. The pact between the Alliance forces and the Darkspear Revolution resulted in the Siege of Orgrimmar, which saw Garrosh Hellscream deposed and taken away to be put on trial for his crimes against the people of Azeroth.

Notable battles and events

War in Northrend

A minor front of the war, most of the outposts in Northrend were left manned with skeleton garrisons following the end of the War against the Lich King. Most skirmishes and battles were fought during the war, though minor skirmishes took place following the end of the war.

Notable battles and events

War in Pandaria

With the discovery of a new continent, the wars of the Alliance and the Horde were brought to the foreign shores of Pandaria.

Notable battles and events

War on Outland

A fringe front, the majority of the confrontations between the Alliance and the Horde on the broken land of Draenor were fought between the Congregation of the Silver Hand, comprised primarily of the forces of the Clergy of the Holy Light, the Kingdom of Lordaeron Restored and the League of Lordaeron, and a primarily Sin'dorei expedition headed by the The Sunguard and the Dominion of the Sun.
