Panpacific Empire War
The Panpacific Empire War was a Unification Wars campaign in which the Emperor’s armies conquered the Pan-Pacific Empire, a Terran techno-barbarian power. It belongs to the wider struggle by which the Emperor of Mankind, in the closing decades of the thirty-first millennium, brought the fractured, Age of Strife-ravaged polities of Terra under a single rule before the Great Crusade could begin. The Pan-Pacific Empire, holding the Pacific Rim territories of the shattered planet, is recorded as one of the more technologically capable of these regional powers, its arsenals and fortified holdings drawing on remnants of pre-Age of Strife science that made it a harder target than many of its neighbours. The war followed the pattern of the Emperor’s wider unification effort: negotiation where possible, and where refused, direct assault by his Thunder Warriors and allied Terran forces. Accounts differ on the precise course of the campaign, but the Pan-Pacific Empire’s rulers are held to have resisted absorption longer than several other techno-barbarian states, relying on their military technology and defended cities to slow the Emperor’s advance. As with the Emperor’s other Unification Wars campaigns, the fighting combined pitched battles with the steady collapse of outlying garrisons as resistance was worn down region by region. Defeat brought the Pan-Pacific Empire’s dissolution as an independent power and the absorption of its territory, population, and surviving technical knowledge into the Emperor’s unified Terran dominion, alongside contemporaries such as the Merican States and the other regional empires subdued in the same era. The war stands as one strand of the Unification Wars that made a single, secure Terra possible, the necessary precondition for the Emperor’s later departure on the Great Crusade. No independent Pan-Pacific polity is attested in Imperial records after this period; its memory survives chiefly as one campaign among the many by which Terra itself was made whole.
