Caliphates in the context of "Sultanate of Nejd"

Lebanon, officially the Republic of Lebanon, is a country in the Levant region of West Asia. Situated at the crossroads of the Mediterranean Basin and the Arabian Peninsula, it is bordered by Syria to the north and east, Israel to the south, and the Mediterranean Sea to the west; Cyprus lies a short distance from the coastline. Lebanon has a population of more than five million and an area of 10,452 square kilometres (4,036 sq mi). Beirut is the country's capital and largest city.

Human habitation in Lebanon dates to 5000 BC. From 3200 to 539 BC, it was part of Phoenicia, a maritime civilization that spanned the Mediterranean Basin. In 64 BC, the region became part of the Roman Empire and the subsequent Byzantine Empire. After the seventh century, it came under the rule of different Arab Islamic caliphates, including the Rashidun, Umayyad and Abbasid caliphates. The 11th century saw the establishment of Christian Crusader states, which fell to the Ayyubids and the Mamluks. Lebanon came under Ottoman rule in the early 16th century. Under Ottoman sultan Abdulmejid I, the first Lebanese proto-state, the Mount Lebanon Mutasarrifate, was established as a home for Maronite Christians, as part of the Tanzimat reforms.

Al-ʿAwāṣim (Arabic: العواصم, "the defences, fortifications"; sing. al-ʿāṣimah, اَلْـعَـاصِـمَـة, "protectress") was the Arabic term used to refer to the Muslim side of the frontier zone between the Byzantine Empire and the Umayyad and Abbasid Caliphates in Cilicia, northern Syria and Upper Mesopotamia. It was established in the early 8th century, once the first wave of the Muslim conquests ebbed, and lasted until the mid-10th century, when the Byzantine advance overran it. It comprised the forward marches, comprising a chain of fortified strongholds, known as al-thughūr (اَلـثُّـغُـوْر; sing. al-thaghr, اَلـثَّـغْـر, "cleft, opening"), and the rear or inner regions of the frontier zone, which was known as al-ʿawāṣim proper. On the Byzantine side, the Muslim marches were mirrored by the institution of the kleisourai and the akritai (border guards).

The term thughūr was also used in the marches of al-Andalus and Transoxiana, and was revived by the Mamluk Sultanate in the 14th century, when the areas traditionally comprising the ʿawāṣim and thughūr in the northern Syrian region and Upper Mesopotamia came under their control.

Jibāl (Arabic: جبال), also al-Jabal (Arabic: الجبل), was the name given by the Arabs to a region and province located in western Iran, under the Umayyad and Abbasid Caliphates.

Its name means "the Mountains", being the plural of jabal ("mountain, hill"), highlighting the region's mountainous nature in the Zagros. Between the 12th and 14th centuries, the name Jibal was progressively abandoned, and it came to be mistakenly referred to as ʿIrāq ʿAjamī ("Persian Iraq") to distinguish it from "Arab Iraq" in Mesopotamia. The region never had any precisely defined boundaries, but was held to be bounded by the Maranjab Desert in the east, by Fars and Khuzistan in the south, by Iraq in the south-west and west, by Adharbayjan in the north-west and by the Alborz Mountains in the north, making it roughly coterminous with the ancient country of Media.
