Most nations in Asia, Latin America, and Africa experienced some form of "land reform" in the twentieth century. But what is land reform? In her book, The Long Land War: The Global Struggle for Occupancy Rights, Professor Jo Guldi approaches the problem from the point of view of Britain's disintegrating empire. She makes the case that land reform movements originated as an argument about reparations for the experience of colonization, and that they were championed by a set of leading administrators within British empire and in UN agencies at the beginning of the postwar period. Using methods from the history of technology, she sets out to explain how international governments, national governments, market evangelists, and grassroots movements advanced their own solutions for realizing the redistribution of land. Her conclusions lead her to revisit the question of how states were changing in the twentieth century -- and to extend our history of property ownership over the longue durée.
