Rise of Neville Chamberlain [SEP] Introduction
After returning to England in 1897, Chamberlain became a successful businessman in his home city of Birmingham. He was interested in social affairs, and successfully stood for Birmingham City Council in 1911. He became Lord Mayor of Birmingham in 1915. His second term was interrupted in December 1916 when Prime Minister David Lloyd George asked him to become Director of National Service. Chamberlain received little support from Lloyd George in the post, and his eight-month tenure sparked a hatred between the two which lasted Chamberlain's lifetime.
