6 Nation Alliance
An alliance of six nations that went to war against Borogravia when the stroppy jingoistic nation's mad god Nuggan declared the clacks towers to be an 'abomination' leading to Borogravia attacking their neighbours, and cutting down the clacks thus cutting communications across the disc.
The known nations in the Alliance were local nations hostile to Borogravia and fed up of it's constant warmongering, and international powers angry at it's disruption of their trade and communications:
Mouldavia - Neighbour of Borogravia, subject to their aggression in the past
(Two others unnamed)
Once peace had been restored and Borogravia had surrendered with dignity the alliance broke up, with Ankh-Morpork and the dwarves supplying food and goods so that Borogravia would not starve during the winter.
When in the spring Prince Heinrich again tried to press his claim to the throne and invaded Borogravia it was highly unlikely that the Alliance re-formed to help Zlobenia, as this was an act of aggression on their part. In fact, it was speculated by Polly Perks that by being smart and using the clacks, newspapers and public opinion Borogravia could instead get Ankh-Morpork to help them.
