The 19th century saw the rise of one of the largest, most powerful empires of the modern era. The sun never set on the British Empire, whose holdings spanned the globe, in one form or another. Its naval supremacy linked the Commonwealth of Canada with the colonies in South Africa and India, and through them trade flowed east and west. An integral but underutilized part of this vast trade network included China, a reclusive Asian kingdom closed off from the Western world that desired none of its goods. Unfortunately for China, the British had the might of an empire and economic force, not to mention modern arms, on their side. Breaking into China's lucrative trade markets nearly destroyed the nation, severely discredited the Chinese dynasty, wreaked havoc on its people, and further propelled Britain's empire into a dominant economic and military position. The collision of these two empires took many years and caused much bloodshed. In fact, the troubles started well before the eventual hostilities, festering as frustration mounted until finally boiling over.

Though both nations modernized, and China far outweighed Japan in terms of men and materiel potential, the island nation handily won its first modern war. The conflict resulted in Japan's short-term gains in the wake of victory, and the long term disaster for both sides' new roles in Asia, for with the end of Chinese dominance in East Asia came a new era for the region as a whole.

In 1937, the Empire of Japan once more went to war with China, a nation broken into petty warlord fiefdoms and wracked by civil war. The most modern Asian nation enacted a brutal campaign over the fragmented realms that made up China, committing atrocities just as horrendous as their Axis ally in Europe. Despite this, the sheer size of China, coupled with Japan's overextension, allowed the larger, less developed nation to endure.
