The **Three Decades' War** was an international conflict that lasted from 53 to 87 G.E. The conflict was fought primarily by an alliance of the Empire of Shingō, the Fourth Kingdom of Wei, and the Empire of Arlon against the Kingdom of Windsor. The war is generally accepted to have been motivated by competing imperial and colonial ambitions of these states, as the Kingdom of Windsor especially escalated regional tensions prior to the outbreak of war by invading the entirety of the Tsukimoto islands, which had been held by the colonial government of the Rösdal Kingdom.

## Events of the War

The war officially began in 53 G.E. with Windsor's invasion of the Chūō region and the Kingdom of Wei. Windsoran diplomats stated the reason for their nation's invasion as a response to the Weian king's attempt to hire spies to poison the king of Windsor. After roughly three years of fighting, the two forces became locked in a stalemate, with troops of both sides entrenched across the Chūō region. The stalemate was officially broken in 58 G.E. when the Empire of Shingō joined the war on the side of Wei in response to Windsoran forces entering and demanding quartering from villagers in southern Shingō.

The next seventeen years was characterized by several periods of on-and-off fighting between the newly-formed Shingō-Weian alliance against the Kingdom of Windsor, with little territory being gained by either side. In 78 G.E., the Empire of Arlon, seeking to expand its colonial holdings in the region, joined the conflict in support of the Shingō-Weian alliance and subsequently began to push Windsor forces out of the Tsukimoto islands. The advances of Arlon, however, wer brought to an abrupt halt by a civil war in the nation's homeland, which ultimately led the Arlonian colony state of Anholt to declare its independence and act as a safe haven for detractors of the new government in the nation's homeland.

The Battle of the Amaiwa Straits, a major naval conflict, occurred in 76 G.E., during which the Shingōan fleet defeated the Windsoran fleet and gained control of the seas to the northwest of Tsukimoto for the remainder of the war. By 86 G.E., Shingō-Weian soldiers, aided by various mercenary groups from the new state of Anholt, managed to secure the majority of the Tsukimoto islands and were preparing for a full-scale invasion of the capital of Windsor's Tsukimotoan colony. Within the following year, Anti-Windsor forces, which were additionally aided by Tsukimotoan independence fighters, had managed to overwhelm the undersupplied defenders of the colonial capital and take the city. In 87 G.E., a peace treaty was negotiated between the involved states of the war and the conflict was brought to an end.

## Outcome

The outcome of the war effectively left the Empire of Shingō as the dominant imperial power in the region, as the Empire would annex the Tsukimoto islands following the withdrawal of Windsor forces at the end of the conflict. The unstable Fourth Kingdom of Wei was also left indebted to Shingō, as it had sourced the majority of its rations and munitions from the Empire. A year after the end of the conflict, Shingō proclaimed itself as the new Greater Shingō Empire, inspiring feelings of uncertainty across the region.
