Ahmadiyya in the United Kingdom began in 1913 with the pioneering efforts of Chaudhry Fateh Muhammad Sial. Sial was the first missionary sent to the UK under the direction of Hakeem Noor-ud-Din. Hakeem was the first successor of Mirza Ghulam Ahmad, whom the Ahmadis consider the promised messiah. Not many years later, the need for a mosque in the UK became evident and in 1925, Fazl Mosque was constructed became the city's first mosque. The sect expanded to include Ahmadi mosques and mission houses across the country. The Baitul Futuh mosque stands as the largest in western Europe.
