It led to an Imperial intervention with Moff 's deploying 150,000 troops to the region. The initial takeover of several worlds by resistance groups was reversed by Imperial forces and the House Defence League, but a low level insurgency would continue until the, with several escalations. Due to its remote backwater location, the would not establish presence there until 3 ABY. In the end, the resistance groups failed to overthrow the nobles, who reestablished their control over the region in 4 ABY.

Background
The region remained isolated from much of  and only joined the  shortly before the. It was a collection of feudal monarchies ruled by a group of noble houses, most notably by House, along with , , and. Those were the most powerful lineages, but there were 13 other minor noble families. The region did not have a central government besides an occasional council of the houses that convened to address issues. These Human aristocrats controlled the region's native populations essentially as slaves on their feudal agricultural worlds. They ignored the anti-slavery laws in the, but the Republic did not take any meaningful action to change the situation.

The Ancient Houses was not directly involved in the Clone Wars but the region's remoteness led to some Separatist-affiliated groups taking refuge within its borders, and disseminating propaganda to its population. This continued over the years of the war, and many dissidents were inspired by the example of the Separatist resistance. After the rise of the, the new limited its interference in the region's affairs and abolished the anti-slavery laws, allowing the nobles to continue their practice openly. Emperor recognised the loyalty of Lord  by granting his family a new Imperial peerage, the Grand Duchy of Senex-Juvex, as well as making them the head of the new centralised government for the region, as a  of the Empire.

Around that time, due to Senex-Juvex becoming part of the Republic, some of the Human peasant class came to acquire more knowledge about the greater galaxy and even were able to travel abroad. They learned about the state of galactic affairs and how the wealthy functioned. Several of these returned to Senex-Juvex and began contributing to the spread of ideas challenging the aristocratic regime, and also to abolitionist thinking among the slave species.
