This is a new edition of Geoffrey Parker's much-admired illustrated account of how the West, so small and so deficient in natural resources in 1500, had by 1800 come to control over one-third of the world. Parker argues that the rapid development of military practice in the West constituted a 'military revolution' which gave Westerners an insurmountable advantage over the peoples of other continents. This edition incorporates new material, including a substantial 'Afterword' which summarises the debate which developed after the book's first publication.
