Socotra
Religion

The earliest account concerning the presence of Christians in Socotra stems from the early-medieval 6th century CE Greek merchant Cosmas Indicopleustes Later the Socotrans joined the Assyrian church. During the 10th century, Arab geographer Abu Muhammad al-Hasan al-Hamdani recorded during his visits that most of the islanders were Christian.

Christianity went into decline when the Mahra sultanate took power in the 16th century, and the populace had become mostly Muslim by the time the Portuguese arrived later that century. An 1884 edition of Nature writes that the disappearance of Christian churches and monuments can be accounted for by a Wahhabi excursion to the island in 1800. Today the only remnants of Christianity are some cross engravings from the first century CE, a few Christian tombs, and some church ruins.
