9.7% of Sri Lankans adhere to Islam; mostly from the Moor and Malay ethnic communities on the island. Christianity According to a Christian tradition, Christianity was introduced by Thomas the Apostle in Sri Lanka (as well as India) during the 1st century. The first evidence of Christianity in Sri Lanka is the account in the 6th-century Christian Topography, which says a community of Persian Nestorians lived on the island. The Anuradhapura cross, discovered in 1912, is probably a relic of this community. However, the population of Christians in Sri Lanka didn't dramatically increase until the arrival of Portuguese missionaries during the 15th century. In the 17th century, the Dutch took over Sri Lanka and Dutch missionaries were able to convert 21% of Sri Lanka's population to Christianity by 1622. In 1796 the Dutch were displaced by the British and in 1802 Ceylon became a Crown colony. Anglican and other Protestant missionaries arrived at Sri Lanka during the early 19th century, when the British took control of Sri Lanka from the Dutch. Under British rule missionary work was undertaken by English societies: Baptist, Wesleyan Methodist, the CMS and SPG. The Salvation Army and Jehovah's Witnesses are also present in Sri Lanka. The percentage of Christians has slowly declined from the height of 13% in 1891 they were 12.6% and numbered were 302,000. In 2012 they 7.4%. By the 1980s, the population of Christians was mostly concentrated in the northwest of Sri Lanka and in the capital where they are 10% of the population. Of these Christians, over 80% are Roman Catholics while the rest are predominantly Anglicans, Methodists and other Protestants. Baháʼí Faith Adherents of the Baháʼí Faith have been present in Sri Lanka since 1949. The first Baháʼí resident in Colombo was a physician from India, Dr. M.E. Lukmani. Its population grew in the 1950s and by 1962, its first administrative body for the national level (the National Spiritual Assembly of the Baháʼís of Sri Lanka) was elected.
