Emir Youssef Shehab in the early 1800s brought Christians to the town, in hope of getting better crop and thus better taxes. Since then the village has become a Christian village, with most of its believers members of the Greek Orthodox Church.
The name Douma is of Greek origin meaning "house", "palace" or "castle". Douma is also named "Douma El Hadid" (Douma of Iron or Iron-Douma) due to the abundance of iron found it its soil and the superior craftsmanship of its blacksmiths. The arming industry established under Ibrahimn Basha's regime encouraged many people from Showeir to come and settle in Douma since opportunities of work were plentiful at the time.
The majority of the infrastructure and housing in Douma was built between 1881 and 1914. This was the golden age in the life of Douma financed by the money sent by emigrants in Brazil, Argentina and the USA.
