In 1841, the Welsh sent their first missionary, Thomas Jones, to evangelise the tribal peoples of the Khasi Hills of north-east India. This book follows Jones from rural Wales to Cherrapunji, the wettest place on earth and now one of the most Christianised parts of India. As colonised colonisers, the Welsh were to have a profound impact on the culture and beliefs of the Khasis. The book also foregrounds broader political, scientific, racial and military ideologies that mobilised the Khasi Hills into an interconnected network of imperial control. Its themes are universal: crises of authority, the loneliness of geographical isolation, sexual scandal, greed and exploitation, personal and institutional dogma, individual and group morality. Written by a direct descendant of Thomas Jones, it makes a significant contribution in orienting the scholarship of imperialism to a much-neglected corner of India, and will appeal to students of the British imperial experience more broadly.
