In an alternate timeline where the Federation and Klingons jointly colonized planets under the Organian Peace Treaty, Benecia City was the first Federation colony on Benecia. It would also serve as the capital. Founded sometime in 2270, Benecia City was soon replaced as the largest Federation settlement on the planet by Zenith Colony in 2275. That same year, the colony experienced a major earthquake which caused much damage. Many suspected the Klingons of having deliberately created the earthquake as a means of driving off Federation settlers and laying claim to the entire planet.
