Congratulations to Patricia O’Brien for the publication of her new book, a biography of Ta’isi O. F. Nelson, a leading Sāmoan businessman who was blamed for instigating Sāmoa’s long-running non-violent campaign for justice (the Mau) that challenged New Zealand, Britain and the newly minted powers of the League of Nations between the wars. Using many new sources, this book adds new layers to the story of Indigenous resistance and the global crisis of empire after World War I.
