Neville Chamberlain was a British politician who served as Prime Minister from 1937 to 1940. He is best known for his policy of appeasement towards Nazi Germany, particularly his negotiations with Adolf Hitler in the lead-up to World War II. Chamberlain's approach was criticized after the war, as it was seen as having failed to prevent the outbreak of conflict. However, he also made significant domestic policy reforms during his time in office, particularly in the areas of social welfare and housing. Chamberlain's legacy remains a subject of historical debate.
