The Portland-Boise War, also called the Oregon-Idaho War or the Three Months War was a military conflict between the American states of Oregon and Idaho.To this day, the exact reason for the war is unknown, but many speculate it has to do with Oregon not allowing Idahoans to travel freely between the two states. This was due to the fact Oregon was facing an economical crisis after a strike in Oregon's capital, decreasing the amount of consumers. The war lasted for three months before the United States military put an end to the war.

On Saturday, May 16th, 2020, at approximately 1:36 PM GMT, Oregon's military plowed through the Idahoan counties of Owyhee, Washington and Adams. The county seat of Owyhee, Murphy, was completely plundered. Over half of its population was massacred, and act condemned by the United States and Brad Little, who retaliated almost immediately. At 4:32 PM, Oregon forces marched into Nampa. Idahoan forces dug down and defended the city. The battle was fought for 4 days, until Oregon forces eventually retreated. Unfortunately, a total of 32.394 civilian/military lives were lost as a result. The Battle of Nampa was a decisive victory for Idaho, which now started pouring troops into Oregon's mainland. On Tuesday, May 20th, 2020, at 10:14 AM, Idahoan forces broke through Oregonian defences placed between Owyhee and Malheur counties. Around 5,000 soldiers participated in the invasion of Ontario, Oregon.

At this point, Oregon's northern neighbour, Washington,was becoming sceptical of Oregon's next plan of attack, which was the use of a neurotoxin.
