Please be considerate for this response. For this response, I am using only the information from the first series.According to that series, the United Federation of Planets was a new creation by the second or third year of the USS Enterprise's mission. Before that year, the U.F.P. was preceded by Earth's U.E.S.P.A. and other planets' navies.
Prior to 2195, the first year of the USS Enterprise's mission, there was a terrible war that ravaged the galaxy. ("The Mark of Gideon") This war involved planets (Earth, Vulcan) and individuals (Officer Kirk, Captain Garth of Izar). ("Whom Gods Destroy") The war ended with the Battle of Axanar. (ibid.)
The Axanarians, who witnessed the war, helped the two warring sides to write a treaty that ushed in peace and galactic unity. Their dream was the U.F.P. (ibid.)
By 2197, the U.F.P. was firmly founded.

There are several disparities between this chronology-the innovation of warp drive and its relation to the Eugenics War, the founding of the U.F.P., etc-to the later chronology as established by canon.
This proves I think that the later series have damaged the canonicity of the first series. The coming series, Enterprise, will add damage to the canonicity of the first series and will not be the series that started the damaging. TNG is the first series to do damage.
