"Let's purify the universe."
- – Homeguard slogan
Homeguard was a paramilitary xenophobic Human group that opposed any involvement with alien races. The group had been growing in popularity on Earth by 2258. In that year, a leader of the movement was convicted, members of this group attacked Minbari poet Shaal Mayan and Centauri nobles Kiron Maray and Aria Tensus, and framed Garibaldi while they plotted to kill the President.
With the rise of the Clark Administration, Homeguard was effectively absorbed by Nightwatch, Clark's own xenophobic paramilitary group organized by Mini-Pax. Note, however, that Clark's agent referred to Homeguard as "a bunch of misfits." In all likelihood this is because Homeguard was more of a "grassroots" organization as opposed to the more clandestine works done by Nightwatch and Clark's other agents.
