[Star Wars] How long did it take for the Rebels to really organize(legends)?

In Legends? The Rebels were basically doing their thing right from the end of the Clone Wars, though there wasn't an actual Rebel Alliance ^TM, wherein the various leaders of some of the biggest Rebel factions officially joined together with the Treaty of Corellia, until about a year and a half or so before the Battle of Yavin.
