The Blitz was a sustained bombing campaign carried out by Nazi Germany against the United Kingdom during World War II, primarily from September 1940 to May 1941. The main target was London, but other cities like Coventry and Birmingham were also heavily bombed. The goal was to weaken British morale and disrupt war production. During the Blitz, the German Luftwaffe dropped thousands of tons of bombs, causing significant destruction and loss of life. Despite the devastation, the British people showed resilience, using air raid shelters and blackout measures to protect themselves. The Blitz ultimately failed to break British resolve, contributing to the eventual defeat of Germany.
