The Jedi vs Sith era was a vague and undefined era of time categorized by frequent wars and great political and social upheaval. During this time, the number of Sector-scale Political entities was at one of the highest in recorded Galactic History. This era was known to overlap with several others, most notably the Legacy era, with perhaps the most noteworthy occurrences happening after the Yuuzhan Vong War and Second Galactic Civil War.
