DAMASCUS – The Islamic State of Iraq and al-Sham (ISIS) has demanded that Christians in the city of Raqqa pay a levy in gold and curb displays of their faith in return for protection, according to a statement posted online Wednesday, Feb. 26.

ISIS said it would ensure Christians’ safety in exchange for the levy and their adherence to restrictions on their faith, citing the Islamic legal precept of “dhimma.”

It said Christians must not make renovations to churches or other religious buildings, display religious insignia outside of churches, ring church bells or pray in public.

It demanded every Christian male pay a tax of up to 17 grams of gold, a levy that was common in Muslim states centuries ago.

The directive also bans Christians from owning weapons and from selling pork or alcohol to Muslims or drinking wine in public.

The concept of dhimma, governing non-Muslims living under Islamic rule, dates back to the seventh century but was largely abolished during the Ottoman reforms of the mid-19th century.

Raqqa was the first and only city to fall completely under rebel control last year.
