An important branch of the Rimma, the Shapani Bypass, grew increasingly important in later years, and some considered it part of the Rimma for all practical purposes.
Another branch, which was a continuation of the Rimma, was the Trition Trade Route. The Trition began at Karideph and continued on into the Kathol sector.
When the Herglic Trade Empire joined the Galactic Republic in 13,000 BBY, the Hidakai Pool begun to develop. From there, Herglics and Givin theorists knit together the Rimma; Sullustan merchants who came to Tapani sector and having innate navigational talents, found ready jobs as scouts, pilots and hyperspace mappers and established the Route 5500 BBY.
The Rimma Trade Route was seized by the Sith Empire as part of their initial infiltration of Republic space in 3681 BBY. Consequently, it was economically strangled by imperial sanctions.
Its dominant worlds (Denon and Eriadu) are ruled by humans.
Commerce along the Route enriched SoroSuub Corporation, the Tapani sector and colonization of the south.
In the years before the Invasion of Naboo, the Trade Federation had a de-facto monopoly on the Rimma Trade Route. Subsequently, the planets on the route were the main recruitment grounds for the Nebula Front.
