Abdullah Quilliam: The Englishman Who Built Britain’s First Mosque

In the heart of Victorian Britain, at the height of the British Empire, one man made history by embracing Islam and laying the foundations for organised Muslim life in the UK. His name was Abdullah Quilliam—a Liverpool-born solicitor, writer, and scholar who went on to become the first official Shaykh al-Islām in Britain, appointed by the Ottoman Caliph Sultan Abdul Hamid II.

From Law to Islam

Born William Henry Quilliam in 1856 to a Methodist family, he was deeply influenced by ethical values and social reform. A journey to North Africa in the early 1880s exposed him to the spiritual depth of Islam, leading to his conversion in 1887. Upon returning to Liverpool, he publicly embraced Islam and became a passionate voice for dawah and interfaith dialogue.

Britain’s First Mosque and Islamic Institute

Quilliam quickly established the Liverpool Muslim Institute, the first functioning mosque in Britain, along with a publishing house and a school for Muslim children. His book The Faith of Islam was widely circulated and translated, becoming a cornerstone of English-language Islamic literature in Europe.

Appointed by the Caliph

In 1893, Quilliam received official recognition from the Ottoman Caliphate and was appointed Shaykh al-Islām of the British Isles—a role that involved both religious leadership and diplomatic representation of the Caliph in the West. He also represented the Ottoman Sultan at mosque inaugurations in West Africa and maintained close ties with Muslim communities across the globe.

Defender of the Ummah

Quilliam used his platform to defend the Ottoman Caliphate, counter British imperial policies, and oppose anti-Muslim propaganda in Victorian society. His leadership saw over 50 Britons embrace Islam under his guidance. He maintained strong relations with Muslim leaders in Africa, India, and the Middle East.

Legacy

Following the fall of Sultan Abdul Hamid II and growing anti-Ottoman sentiment in Britain, Quilliam’s influence declined. He continued to support Islamic causes discreetly under the name Haroon de Leon until his death in 1932. He was buried in Woking, alongside other early British Muslims.

Today, Abdullah Quilliam is remembered as a pioneering figure in British Islamic history—a man who bridged cultures, defended the Ummah, and left behind a legacy that still resonates.
