The Federation was founded in [[San Francisco]], [[Earth]] in [[2161]]. The seeds of the Federation were planted during a temporary alliance in [[2154]], in the search for a [[Romulan drone ship]]. It was this that first brought together the five species that would found the Federation: [[Human]]s, [[Vulcan]]s, [[Andorian]]s, [[Tellarite]]s, and [[Alpha Centauran]]s. After the crisis, these four species remained together, founding the precursor to the Federation, called the [[Coalition of Planets]], a year later. Other species soon joined: the [[Denobulan]]s, the [[Rigelian]]s, the [[Coridanite]]s, and several others. Over the next several years, the ties between the members of the Coalition strengthened and became more structured, until, finally, in 2161, the Coalition became the Federation.
