Why Did Britain Declare War on Germany?

During World War II over 70,000,000 people were killed, the majority of whom were civilians. This was the deadliest conflict in human history. Sir Winston Churchill was the Prime Minister of Britain during this time. The Axis powers (Germany, Italy and Japan) were on a quest for world domination. Britain had no choice but to join the allies in order to put an end to this attempt at world domination by Hitler’s Third Reich and the others. For more information, look here:
