Chosen answer:It depends on whether you choose to view the Expanded Universe (non-movie) stuff as part of the proper Star Wars "universe", but some important events include the start of the Rebellion, Han Solo rescuing Chewbacca from Imperial capture, Lando Calrissian losing the Millennium Falcon to Han, and of course, the capture of the Death Star plans by the Alliance. As of 2016 the events of Rogue One are documented on film, together with other new canonical novels, comics, TV series, etc., and the Expanded Universe has been disregarded.
