The plans were brought to the Rebel Alliance by Princess Leia Organa, with the help of companions such as Luke Skywalker and Han Solo. In 0 BBY, the Alliance scored its first major victory against the Empire by stealing the plans to the Death Star, the Empire's planet-destroying battle station, in the Battle of Scarif. The war had begun by the year 4 BBY and officially began at the formal establishment of the Rebel Alliance in 2 BBY with Mon Mothma's Declaration of the Rebel Alliance. A number of these cells eventually joined together and became the Alliance to Restore the Republic. After Supreme Chancellor Palpatine, secretly the Sith Lord Darth Sidious, transformed the Republic into the Empire and destroyed the Jedi Order, many rebel cells began fighting the Empire. The origins of rebellion could be traced to the Clone Wars, when rebel cells were equipped by the Galactic Republic and the Jedi Order to fight against the Confederacy of Independent Systems.

The Galactic Civil War ( 4 BBY– 5 ABY), also referred to as the revolution or the rebellion, was a galactic power struggle in which the Alliance to Restore the Republic waged a rebellion against the ruling Galactic Empire in an attempt to restore democratic rule to the galaxy.
