Imperial Guards was a Pirates subtheme introduced in 1989 that eventually replaced the Imperial Soldiers as main adversaries of the pirates. Some of the older Imperial Soldiers' sets that were still in production were re-categorized as part of the Imperial Guards faction until their discontinuation in 1995.
