The move to Hafeld coincided with the onset of intense father-son conflicts caused by Hitler’s refusal to conform to the strict discipline of his school. Alois Hitler’s farming efforts at Hafeld ended in failure, and in 1897 the family moved to Lambach. The eight-year-old Hitler took singing lessons, sang in the church choir, and even considered becoming a priest. In 1898 the family returned permanently to Leonding. Hitler was deeply affected by the death of his younger brother Edmund, who died in 1900 from measles. Hitler changed from a confident, outgoing, conscientious student to a morose, detached boy who constantly fought with his father and teachers.
