What you need to know about Ahsoka Tano before the new Ahsoka series
So you didn't watch Clone Wars or Rebels....
If you did not watch the Clone Wars or Rebels you have really missed out. The first two seasons of Clone Wars were a bit milk toast as LucasFilm was not sure of kids were watching the show or adults. Eventually the numbers came in and the demo was mostly adults, after that the show was taken up a level and the Clone Wars became perhaps the greatest Star Wars content period.
When Disney bought LucasFilm they too assumed it would be mostly kids watching Rebels. Disney learned the same lesson. The last two seasons of Rebels is amazing, but it still never quite achieved the story and production value of Clone Wars.
Between Episodes II and III of the prequels, Anakin is promoted to Jedi Knight and is assigned a Padawan, Ahsoka Tano. The Clone War rages on for seven years.
