During which years did the Second World War take place?
1939 to 1945.
The Second World War lasted from 1939 to 1945, six years that reshaped Britain and the world. It follows directly from the earlier history of rising tensions in the 1930s and comes right before 1948, when the NHS began in the aftermath. Learning the war's dates alongside its aftermath makes both easier to hold onto.
Why it matters: This is one of the highest-relevance dates in the chapter and the anchor point for everything that follows in modern British history.
Memory hook: Thirty-nine to forty-five. World War Two stayed alive.
