Jund al-Urdunn in the context of "Jordan Valley (Middle East)"

Bilad al-Sham (Arabic: بِلَاد الشَّام, romanized: Bilād al-Shām), often referred to as Islamic Syria or simply Syria in English-language sources, was a province of the Rashidun, Umayyad, Abbasid, and Fatimid caliphates. It roughly corresponded with the Byzantine Diocese of the East, conquered by the Muslims in 634–647. Under the Umayyads (661–750), Bilad al-Sham was the metropolitan province of the Caliphate and different localities throughout the province served as the seats of the Umayyad caliphs and princes.

Bilad al-Sham was first organized into the four ajnad (military districts; singular jund) of Dimashq (Damascus), Hims (Homs), al-Urdunn (Jordan), and Filastin (Palestine), between 637 and 640 by Caliph Umar following the Muslim conquest. The jund of Qinnasrin was created out of the northern part of Hims by caliphs Mu'awiya I (r. 661–680) or Yazid I (r. 680–683). The Jazira (Upper Mesopotamia) was made an independent province from the Mesopotamian part of Qinnasrin by Caliph Abd al-Malik in 692. In 786, the jund of al-Awasim and al-Thughur were established from the northern frontier region of Qinnasrin by Caliph Harun al-Rashid. As centralized Abbasid rule over Bilad al-Sham collapsed in the 10th century, control over the region was divided by several potentates and the ajnad only represented nominal divisions. The Abbasids and the Egypt-based Fatimid Caliphate continued to officially recognize the province and its ajnad until the Crusader invasions of the coastal regions in 1099.

Hassan ibn Malik ibn Bahdal al-Kalbi (Arabic: حسان بن مالك بن بحدل الكلبي, romanized: Ḥassān ibn Mālik ibn Baḥdal al-Kalbī, commonly known as Ibn Bahdal (Arabic: ابن بحدل, romanized: Ibn Baḥdal; d. 688 or 689), was the Umayyad governor of Palestine and Jordan during the reigns of Mu'awiya I (r. 661–680) and Yazid I (r. 680–683), a senior figure in the caliph's court, and a chieftain of the Banu Kalb tribe. He owed his position both to his leadership of the powerful Kalb, a major source of troops, and his kinship with the Umayyads through his aunt Maysun bint Bahdal, the wife of Mu'awiya and mother of Yazid. Following Yazid's death, Ibn Bahdal served as the guardian of his son and successor, Mu'awiya II, until the latter's premature death in 684. Amid the political instability and rebellions that ensued in the caliphate, Ibn Bahdal attempted to secure the succession Mu'awiya II's brother Khalid, but ultimately threw his support behind Marwan I, who hailed from a different branch of the Umayyads. Ibn Bahdal and his tribal allies defeated Marwan's opponents at the Battle of Marj Rahit and secured for themselves the most prominent roles in the Umayyad administration and military.

Tiberias (/taɪˈbɪəriəs/ ty-BEER-ee-əs; Hebrew: טבריה, Ṭəveryā; Arabic: طبريا, romanized: Ṭabariyyā) is a city on the western shore of the Sea of Galilee in northern Israel. A major Jewish center during Late Antiquity, it has been considered since the 16th century one of Judaism's Four Holy Cities, along with Jerusalem, Hebron, and Safed. In 2023 it had a population of 51,476.

Tiberias was founded around 20 CE by Herod Antipas and was named after Roman emperor Tiberius. It became a major political and religious hub of the Jews in the Land of Israel after the destruction of Jerusalem and the desolation of Judea during the Jewish–Roman wars. From the time of the second through the tenth centuries CE, Tiberias was the largest Jewish city in Galilee, and much of the Mishna and the Jerusalem Talmud were compiled there. Tiberias flourished during the Early Muslim period, when it served as the capital of Jund al-Urdunn and became a multi-cultural trading center. The city declined in importance over time due to earthquake damage and foreign incursions. After the Galilee earthquake of 1837 the city was rebuilt and grew steadily following the First Jewish Aliyah in the 1880s.

Abu al-A'war Amr ibn Sufyan ibn Abd Shams al-Sulami (Arabic: أبو الأعور عمرو بن سُفيان بن عبد شمس السلمي, romanized: ʾAbū al-ʾAʿwar ʿAmr ibn Sufyān ibn ʿAbd Shams al-Sulamī), identified with the Abulathar or Aboubacharos (Greek: Ἀβουλαθάρ, Ἀβουβάχαρος) of the Byzantine sources (fl. 629–669), was an Arab admiral and general, serving in the armies of the Rashidun caliphs Abu Bakr (r. 632–634), Umar (r. 634–644) and Uthman (r. 644–656) rejecting the fourth Rashidun caliph Ali (r. 656–661), instead serving Umayyad caliph Mu'awiya I (r. 661–680).

He was one of the last prominent members of the Banu Sulaym tribe to convert to Islam, and fought against Muhammad at the Battle of Hunayn in 630. After becoming a Muslim, he took part in the conquest of Syria in the 630s and fought at the Yarmuk. Later, he commanded the Arab navy during the campaigns against the Byzantines in the eastern Mediterranean, including the decisive Muslim victory at the Battle of the Masts in 654. His army was also allegedly responsible for the destruction of the colossus of Rhodes. From the First Fitna until his disappearance from the historical record in the 660s, Abu al-A'war served Mu'awiya in a number of capacities, including as a commander and negotiator at the Battle of Siffin, an operative of Amr ibn al-As in Egypt, a tax administrator in Palestine and the governor of Jordan; he had held the latter post since the reign of Uthman.
