[Dragonball Z] What has happened with the Freeza empire ever since Lord Freeza's death?

Ever since Freeza and his highest ranking men were killed by the Super Saiyan what has changed with his empire? Did a new dictator take over in the power vacuum? What about all the conquered planets? I never really payed attention to these events when they happened so I'd like to know what has changed.

Absolute chaos. Freeza was a tyrant, but like most tyrants who are in power for a long time, he at least kept order. The initial period after his death was a complete fracture in basic societal order for an entire generation. Warlords, former lieutenants with considerable powers under Freeza and Coola, all vied for control while ruthlessly subjugating those they controlled. Unlike Freeza, they had no interest in control and order, just their own self-interest. Millions died and billions suffered. 

After a generation, factions of resistance organized and were able to start overthrowing some of the weaker warlords, gaining the freedom of their subjects who in turn quickly joined the rebellion.While most of the super-powered individuals were power-hungry warlords, some were of conscience and joined the rebellion. This snowballed into a galactic civil war. The rebellion was so powerful that warlords were forced to set aside their differences and unite as an oligarchical empire to fight the more democratic rebellion. Eventually, the rebellion won. They decided to dash the war from the history books. The elected leaders of the rebel factions all met on Courscant and signed the Galactic Constitution, establishing a Galactic Senate. Those with special powers who had fought with the rebels founded the Jedi Order and swore to defend the Galactic Republic. 

Of course, this was all a long time ago, in a galaxy far, far away.
