The Molossia-Mustachistan War took place from 22 May - 8 June 2006, between the Republic of Molossia and Molossia's puppet state, the nation of Mustachistan. The roots of the conflict lay in conflicting territorial claims, a situation aggressively pursued by Mustachistan. Following the outbreak of armed conflict in late May 2006, the Mustachistanis were defeated in three separate battles and sued for peace. Mustachistan was the tongue-in-cheek creation of a friend of President Baugh of Molossia, who called himself Sultan Ali-Ali Achsenfree. Sultan Ali founded his own nation not only to participate in the world of small nations, but also as a bit of competition for Molossia.
The Molossian Naval Infantry was slowed by weather in late May in its advance against Mustachistani forces. However, as events unfolded slowly in the west, the nascent Eastern Front exploded into activity with a battle on Lake Jean, near the Protectorate of New Antrim. Lake Jean had been the target of Mustachistani forces seeking not only to gain a foothold in New Antrim, but also to divert resources from the developing campaign near the Molossian Home Territories.
