Today we’re very lucky to be joined by Kalathmika Natarajan, who has just published a must-read intervention in migration history: Coolie Migrants, Indian Diplomacy: Caste, Class and Indenture Abroad, 1914–67 – Get a copy here! Kala is Lecturer in South Asian History, and in this conversation she takes us through the entanglement of emigration, indenture, and diplomacy in 20th century India. We discuss indentured labour in Ceylon, the appearance of Hindu missionaries in the Caribbean, and the decisive influence of caste. We had to cut this one a little short due to the sudden recollection that we both had to teach.
