The government on the planet Toydaria, located in the Mid Rim, operated as a feudal monarchy. Toydarian royals governed the lands based on a long-established feudal structure. During the era of the Galactic Civil War, the city of Riar had been under the control of the Reeol line for approximately a hundred years, with Baron Reeol holding both ownership and dominion.
The feudal Empire employed a governmental framework where individuals and clans pledged allegiance to ruling lords. These lords, in turn, could be connected to higher-ranking figures, such as the Emperor or their heirs, known as princes. The Jedi Knights belonging to the Jedi clans also committed themselves to serving specific lords.
This system was in practice as early as the failed Sith rebellion. In this rebellion, the Sith, a splinter group of former Jedi desiring self-determination, rose up against aspects of the government, including the constant warfare among feuding lords. The uprising prompted rival lords to create alliances and oppose the Sith collectively. The Empire emerged from the failed rebellion stronger than it had been for centuries. Another consequence was the promotion of Jedi Knights to the status of Jedi lords.
The concept of feudalism, specifically as a feudal monarchy, was first introduced into Star Wars canon continuity in Ghosts of Dathomir, a 2017 resource for Fantasy Flight Games' Star Wars Roleplaying Game.
Feudalism was a prominent feature, although not explicitly named, in Ronin: A Visions Novel, a 2021 book by Emma Mieko Candon that expands upon the universe of the Star Wars: Visions short film "The Duel." The Empire's version of feudalism drew specific inspiration from Japanese feudalism as it existed historically in Japan.
