Anagarika Dharmapala was a Sri Lankan Buddhist revivalist who played a central role in the 19th-century revival of Sinhala Buddhism and its spread to the West. He founded the Maha Bodhi Society in 1891 to restore the Mahabodhi Temple at Bodh Gaya to Buddhist control, and represented Buddhism at the World Parliament of Religions in Chicago in 1893.
Dharmapala means 'protector of the dharma' in Pali, while Anagārika means 'homeless one,' describing a formal status midway between monk and layperson. Dharmapala was the first person in modern times to adopt this status as a permanent, full-time vocation.
Anagarika Dharmapala was born on the 17th of September 1864 in Colombo, Ceylon. His birth name was Don David Hewavitarne, and his parents, Don Carolis Hewavitharana and Mallika Dharmagunawardhana, were among the wealthiest merchants in Ceylon at the time.
Dharmapala founded the Maha Bodhi Society in Colombo in 1891, moving its offices to Calcutta in 1892. Its central aim was the restoration of the Mahabodhi Temple at Bodh Gaya to Buddhist management.

Protestant Buddhism is a term coined by scholar Gananath Obeyesekere to describe a form of Buddhism shaped by Protestant ideals such as freedom of conscience and the importance of the laity, and serving as a protest against Christian missionary activity and colonialism. Dharmapala is regarded as the paradigmatic example of this tradition, with his writings consistently presenting Buddhism as compatible with modern science and rational inquiry.
Anagarika Dharmapala died on the 29th of April 1933 at the Mulagandhakuti Viharaya in Sarnath, Uttar Pradesh, India. He was 68 years old and had taken his higher ordination as a Buddhist monk just two years before his death.
