Awali (river) in the context of South Governorate, Lebanon

South Governorate (Arabic: محافظة الجنوب, romanized: muḥāfaẓat al-Janūb, or simply الجنوب) is one of the governorates of Lebanon, with a population of 590,000 inhabitants and an area of 929.6 km. The capital is Sidon. The lowest elevation is sea-level; the highest is 1,000 meters. The local population is religiously diverse and includes Shia and Sunni Muslims, Druze, Eastern Orthodox, Maronite, Protestant, and Greek Catholic Christians. Temperatures can drop to 4 °C during winter with much rain and snow on the higher ground. In the humid summer, temperatures can rise to 30 °C in the coastal areas. The governorate has several rivers: the Litani, Deir El Zahrani, Naqoura, Awali, Qasmiye, and Hasbani. The area is famous for its citrus and banana farms. Its main cities are Sidon, Tyre and Jezzine.

The Israeli occupation of Southern Lebanon lasted for eighteen years, from 1982 until 2000. In June 1982, Israel invaded Lebanon in response to attacks from southern Lebanon by Palestinian militants. The Israel Defense Forces (IDF) occupied the southern half of Lebanon as far as the capital city Beirut, together with allied Maronite Christian paramilitaries involved in the Lebanese Civil War. The IDF left Beirut on 29 September 1982, but continued to occupy the country's southern half. Amid rising casualties from guerrilla attacks, the IDF withdrew south to the Awali river on 3 September 1983.

From February to April 1985, the IDF carried out a phased withdrawal to a "Security Zone" along the border, which it said was to protect northern Israel. From this point onwards, Israel supported the South Lebanon Army (SLA), the Lebanese Christian paramilitary, against Hezbollah and other Muslim militants. They fought a guerrilla war in Southern Lebanon throughout the occupation.

The South Lebanon conflict was an armed conflict that took place in Israeli-occupied southern Lebanon from 1982 or 1985 until Israel's withdrawal in 2000. Hezbollah, along with other Shia Muslim and left-wing guerrillas, fought against Israel and its ally, the Catholic Christian-dominated South Lebanon Army (SLA). The SLA was supported militarily and logistically by the Israel Defense Forces (IDF) and operated under the jurisdiction of the Israeli-backed South Lebanon provisional administration, which succeeded the earlier Israeli-backed Free Lebanon State. Israel officially names the conflict the Security Zone in Lebanon Campaign and deems it to have begun on 30 September 1982, after the end of its "Operation Peace for Galilee". It can also be seen as an extension of the Lebanese Civil War (1975–1990).

Israel invaded Lebanon in 1978 and in 1982, to end the Palestinian insurgency in South Lebanon and support Lebanese Maronite Christians in the Lebanese Civil War. The 1982 invasion resulted in the Palestine Liberation Organization (PLO) leaving Lebanon and marked the beginning of Israeli occupation. Militant groups began attacking Israeli forces in southern Lebanon in September 1982. Amid rising casualties from guerrilla attacks, the IDF retreated south of the Awali river on 3 September 1983. The IDF began a phased withdrawal from Lebanon in February 1985. It withdrew to a "security zone" along the border on 29 April, and most IDF troops withdrew from the "security zone" on 10 June. A small number of IDF soldiers remained in the zone to support the SLA. Throughout its existence, there were about 1,500 IDF and 2,500 SLA troops in the "security zone" at any given time.
