Mandalore sector

The Mandalore sector, also referred to as Mandalorian Space, was a sector located in the galaxy's Outer Rim Territories. It contained over a thousand worlds, including nearly a thousand worlds that were neutral and not part of the Galactic Republic. Several star systems including the Concord Dawn, Mandalore, and Phindar systems were located in the Mandalore sector.

The sector lay in a key strategic position between Coruscant and the Outer Rim Territories, via the Hydian Way. This made it a contested area in galactic conflicts such as the Clone Wars.

In ancient times, the Mandalorians conquered a significant number of star systems extending out from their homeworld, which were carved up into various fiefdoms between the Mandalorian clans. Mandalorian politics were dominated by large and powerful "Houses", such as House Kryze and House Vizsla, whose primary holdings were typically in the Mandalore system itself. Below the major Houses, smaller and more numerous "Clans" followed them as vassals, serving as local rulers in the colony systems. By the time of the Galactic Empire, many of these colony worlds had been ruled by local Clans for many generations, with centuries' worth of their own local traditions. For example, Clan Wren were sworn vassals of House Vizsla, but Clan Wren directly ruled and was based on the colony world Krownest.

The Mandalore sector was first mentioned in Galaxy Guide 9: Fragments from the Rim, a 1993 Star Wars Legends supplement written by Simon Smith and Eric S. Trautmann for Star Wars: The Roleplaying Game. It became canon when it appeared in "The Mandalore Plot," the twelfth episode of the canon animated series Star Wars: The Clone Wars second season. It was first canonically identified in the 2014 novel Tarkin, written by James Luceno.
