Libya's eastern region,which was the birthplace and driving force in the uprising against Qadhafi, is seeking some sort of semi-autonomy within Libya, complaining of decades of neglect. Local leaders are setting up a regional council for self-government.
The area centered around Benghazi was known as Cyrenaica during the years of Italian rule, and was proclaimed by Idris al-Senusi as the Emirate of Cyrenaica in 1949-51. When it joined with Tripolitania and the Fezzan to become the Kingdom of Libya, Idris became King, so that eastern influence was considerable under the monarchy. After the King's overthrow in 1969, Qadhafi favored the west and came to see the east as a center for dissidence. In the end, it became the engine of his overthrow.
It remains to be seen exactly what sort of "semi-autonomy" the easterners (Cyrenaicans or Barqawis are among the names in use) have in mind, but — combined with continuing quarrels among competing militias, especially in the west around Tripoli — the move could further fuel concerns about the country coming apart. The east controls the oilfields and ports, among other key resources.
