Originally a small hamlet in the Arklay Mountains, the city became heavily industrialized by the investments of the Umbrella Corporation. From 1987 onwards, under the guidance of the Mayor Michael Warren, the city grew rapidly, transforming from a small mountainous community to an industrialized city. However, the city's expansion and modernization was accompanied by a spiraling crime rate. The Raccoon City Police Department (RPD) established the Special Tactics And Rescue Service (S.T.A.R.S.) in 1996 as a countermeasure to the wave of crime.
A viral outbreak involving the T-Virus occurring on Tuesday September 22, 1998 (exactly 61 days after the mansion incident that had occurred on the outskirts of the city), when Umbrella attempted to retrieve a sample of the powerful G-Virus from William Birkin, one of its more reclusive researchers. After he was shot multiple times, Birkin was left mortally injured and, knowing its regenerative capabilities, injected himself with a sample of the G-Virus that Umbrella successfully retrieved. Unfortunately, its mutagenic properties overtook his humanity and transformed him into an unstoppable mutant killing machine. He destroyed the paramilitary team Umbrella Security Service (USS) which had stole the G-Virus from him, and in the process, vials containing the T-Virus were dropped, releasing it into the sewers. The T-Virus was then carried by rats throughout the city, leading to a full-scale outbreak. Leaving the city in total chaos.
