The First Libyan Civil War was a conflict that occurred in Libya from 2011 to 2012. Haftar held a senior position in the Libyan National Army (LNA), which was one of the main factions fighting against the Libyan government led by Muammar Gaddafi. The LNA was supported by NATO, and they eventually succeeded in overthrowing Gaddafi's government and establishing a new government in Libya.
