Commonly referred to as ''the tensions'' or ''the ethnic tension'', the initial civil unrest was mainly characterised by fighting between the Isatabu Freedom Movement (IFM, also known as the Guadalcanal Revolutionary Army and the Isatabu Freedom Fighters) and the Malaita Eagle Force (as well as the Marau Eagle Force). For many years people from the island of Malaita had been migrating to Honiara and Guadalcanal, attracted primarily by the greater economic opportunities available there. The large influx caused tensions with native Guadalcanal islanders (known as Guales), and in late 1998 the IFM was formed and began a campaign of intimidation and violence towards Malaitan settlers. Thousands of Malaitans subsequently fled back to Malaita or to Honiara, and in mid-1999 the Malaita Eagle Force (MEF) was established to protect Malaitans on Guadalcanal. In late 1999, after several failed attempts at brokering a peace deal, Prime Minister Bartholomew Ulufa'aluthe declared a four-month state of emergency, and also requested assistance from Australia and New Zealand, but his appeal was rejected. Meanwhile, law and order on Guadalcanal collapsed, with an ethnically divided police unable to assert authority and many of their weapons depots being raided by the militias; by this point the MEF controlled Honiara with the IFM controlling the rest of Guadalacanal.
