Chief Rabbi Shlomo Amar installed Rabbi Yoel Kaplan as the country's first Chief Rabbi. Recognition of Judaism as an official religion and Rabbi Kaplan as Chief Rabbi were the result of Prime Minister Sali Berisha's efforts. Baháʼí Faith The Baháʼí Faith in Albania was introduced in the 1930s by Refo Çapari, an Albanian politician. Over the recent years several Baháʼí education centres have also been founded. Irreligion Irreligion is and has been historically present among Albanians. Nowadays, estimations of the size of the irreligious population vary widely. The self-declared atheist population has been given figures ranging from 2.5% to 8% to 9% while other estimates of irreligiosity have reported figures of 39% declaring as "atheists"(9%) or "nonreligious"(30%), 61% not saying religion was "important" to their lives, and 72% "non-practising". Albanian national revivalists in the 19th century such as Faik Konica, Jani Vreto, and Zef Jubani were often anti-clerical in rhetoric (Konica said in 1897: "Every faith religion makes me puke", or ), but the first advocate of atheism in modern Albania is thought to have been Ismet Toto, a publicist and revolutionary whose 1934 anti-religious polemic, Grindje me klerin'', was one of the first known works advocating against the practice of religion itself in the Albanian language. Under Socialist rule in 1967, leader Enver Hoxha persecuted and outlawed public religious practice and adopted state atheism. Some well-known Albanian contemporary atheists include Ismail Kadare, Dritëro Agolli, Ben Blushi, Fatos Lubonja, Mustafa Nano, Saimir Pirgu, Diana Çuli, Gilman Bakalli, Fatos Tarifa, Blendi Fevziu , , Elton Deda, and . Religious demography In the 2011 census, 56.7% of Albanians declared themselves to be Sunni Muslims, making Islam the largest religion in the country. Christianity was declared by 16.99% of the population, making it the 2nd largest religion in the country. The remaining portion of the population is either irreligious or belongs to other religious groups. Muslims are found throughout the country, while Orthodox followers are concentrated in the south and Catholics are concentrated in the north. However, this division is not strict, particularly in many urban centers, which have mixed populations. Members of the Greek minority, concentrated in the south, are almost exclusively Orthodox and belong to the Orthodox Church of Albania. In addition to the four traditional religious groups, there are substantial numbers of followers of Protestant denominations, Baháʼís, Jehovah's Witnesses, the Church of Jesus Christ of Latter-day Saints (Mormons), and other
