Imperial Island, by Charlotte Lydia Riley

Historian Charlotte Lydia Riley traces how post-WWII Britain evolved from ruling a quarter of the world's population to a nation confronting waves of immigration from its former colonies and the question of who counts as truly British. Drawing on original research and personal testimony, she connects events from the Notting Hill Carnival and the Suez Crisis to the Iraq War and Brexit, arguing that imperial history still shapes debates over national identity today.
