Adra is identified with the Biblical town of "
Hadrach" mentioned by
Zechariah who noted the city, which was defended by Damascus, was condemned. The
Ghassanids, who were
Arab Christians, dominated Adra and fought against the
Arab Muslim invaders commanded by
Khalid ibn al-Walid in the
Battle of Marj Rahit in July, 634 CE. The battle resulted in a decisive
Rashidun victory and largescale
Islamization took place in the area soon after. Adra contains several graves of
sahaba ("companions" of
Islamic prophet
Muhammad), including most notably that of
Hujr ibn Adi. The
Zengid ruler
Imad al-Din Zengi encamped at Adra in early 1135 before attempting to besiege
Damascus which was controlled by the
Burids. In the early 19th-century a ruined
khan ("
caravansary") was reported by Western travelers to be near the village of Adra. In 2013, it was the site of the
Adra massacre conducted by
Islamist rebels against Syrian minorities. ==References==
