The latest issue of BBC History Magazine is now on sale and is sporting a brand new design. In our new edition Charlotte Higgins investigates why ancient Britons waged guerrilla war against their Roman conquerors.
Elsewhere in the magazine, Robert Cook traces the origins of Martin Luther King's iconic "I Have a Dream" speech, and considers its impact on the civil rights movement.
The August issue also features Linda Porter, who considers the downfall of Mary, Queen of Scots – from throne to scaffold.
Also in this issue, Ben Wilson tells the story of ace U-boat hunter Johnnie Walker, the scourge of German submarines during the Battle of the Atlantic.
Meanwhile, Mark Ormrod assesses the impact of immigrants hailing from across Europe and beyond on 15th-century English society and BBC History Magazine's Spencer Mizen speaks to three leading figures in the Bristol bus boycott of 1963.
Plus, in the first of a new series, Sarah Foot visits Thanet in Kent, the site of St Augustine's arrival in AD 597, to find out more about the rise of Christianity in England.
