So much good stuff from content before the Prequel Trilogy films were released that I’ve forgotten:
I found this helpful thread on a rare visit to the StarWarsEU reddit: Prequels before the prequels
"A Guide to the Star Wars Universe, Second Edition (1994) placed Obi-Wan and Anakin’s births at 60 and 55 BBY respectively.
The Thrawn Trilogy and various other material put the end of the Clone Wars at 35 BBY.
An obscure West End Roleplaying Game piece lists Palpatine as a former Jedi Master.
Jedi Search has Luke saying Yoda lived on Dagobah for hundreds of years.
The ESB Novelization says the Republic fought Mandalorians in the CW, and pretty much everybody agreed the Clones were the main enemy.
The main uniform of the Jedi was what Luke wore in ROTJ.
the Sith were name dropped in the ANH Novelization, but nobody knew what they actually were. Zahn wanted to to have them as what later became the Noghiri, but that was vetoed.
Palpatine came into power after the CW. Mon Mothma was a Senator at the time.
Obi-Wan had another apprentice alongside Anakin during the CW (initially Vader when he was a separate character from Ani, but that was obviously retconned. That guy later became Halagad Ventor).
Owen was Obi-Wan’s brother.
Luke and Leia’s mother stayed with the latter, and died when the twins were four.
Anakin and Obi-Wan still fought on a lava planet.
Obi was implied to be from Tatooine.
Jedi could get married.
Boba Fett’s real name was Jaster Meereel, and he was an adult during the CW.
Vader was already in the suit when the Empire began, he rose the through the ranks as damaged goods (mainly through being Tarkin’s henchman).
Leia’s adoptive father’s first name was Prestor (retconned to be his middle name).
Anakin didn’t know his wife was pregnant at all.
If I remember anything else, I’ll edit it in."

I remember that old “A Guide to the Star Wars Universe” book. I’ll have to dig it out and give it another read! Then onto the Tales Of The Jedi series again, I’ve not read those fully since the Prequel films.
