Outer Rim

The Outer Rim, also known as the Outer Rim Territories, Outer Systems, or simply the Rim, was a sparsely populated region of the galaxy located outside the Mid Rim before Wild Space and the Unknown Regions. The largest region in the galaxy, it was home to diverse worlds and rugged, primitive frontier planets. A region that often went without a major faction holding control over it, the Outer Rim was a home to pirates, smugglers, enslavers, and other criminals throughout the timeline of galactic history.
The Galactic Republic expanded into the Outer Rim throughout its era of governance, making major progress during the so-called High Republic Era, only for dangers like the Nihil marauders and Drengir crisis to hinder the expansion efforts. Inequalities between the richer Core Worlds and the poorer Outer Rim Territories set the stage for resentments that fed several conflicts through the history of the galaxy, including the Clone Wars as well as the Galactic Civil War. Later, the Outer Rim became a major theater of conflict during the Cold War and ensuing First Order-Resistance War.
