In the Star Trek universe, why and how did humanity change from the time of first contact with the Vulcans to the creation of Starfleet? Is there a book that covers this time period?
The basis of the Star Trek universe is that humanity did away with things like poverty, racism, starvation... all the terrible things we have today. It has been said many times that the catalyst was the first contact, when humanity met aliens for the first time and realized they were not alone in the universe.
I just want to know if this time period was ever discussed in detail in a book. Other than it just being mentioned.
