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.
1991 LEGO Sets
1991 brought LEGO Paradisa, a pastel-toned, beachfront subtheme within Town designed to broaden LEGO’s appeal. Pirates added the Imperial Guards, while Space introduced Blacktron II with modular white-and-black spacecraft. The 9V Train system replaced earlier electric formats, simplifying operation with metal track rails. Technic advanced with motorized models like the Control Center, highlighting LEGO’s growing focus on realistic engineering and interactivity.
