The Zanzibar Liberation Front or ZLF was a political and subversive group originating from the Caliphate of Zanzibar.
Around 1905 PD the People's Republic of Haven politically recognized the ZLF in an attempt to destabilize the region and create an pretense for invasion. In response the Caliphate government severed diplomatic relations with the People's Republic and enacted a trade embargo. This made Havenite covert material support for the ZLF difficult. The People's Republic also supported the ZLF by giving them safe bases in the Chelsea and Mendoza Systems.
Before the First Havenite-Manticoran War the ZLF started military actions in Zanzibar System space, directed against the Caliphate's navy. It was also the cover for hostile actions executed by undetected People's Navy warships during the initial phase of Operation Perseus. (HH3)
