جند الأردن
The most notable use of the term was in Syria, where already the Rashidun Caliph Abu Bakr is credited with dividing the region into four "ajnad": Hims (Jund Hims), Damascus (Jund Dimashq), Jordan (Jund al-Urdunn), and Palestine (Jund Filastin). The Umayyad Caliph Yazid I then added the district of Qinnasrin (Jund Qinnasrin). This practice remained unique to Syria and was not emulated in any other province of the Caliphates, which were usually headed by a single governor; hence they were often referred to collectively as "al-Shamat", "the Syrias".
