How transformational leadership differs from previous leadership concepts?

Transformational Leadership differs from previous leadership concepts in that it focusses on the relationship between the leader and follower. There is an increased level of moral and ethical focus, and the leader is interested in the well being of the person being lead, not just getting the job done. Previous leadership concepts focus on the leader themselves, and what traits and behaviours the leader has. Typically they are focussed on a transactional interaction between leader and follower: ie:

You do this job, and get this reward, or punishment, accordingly. Transformational leadership is focussed more on the quality of interation between people. It has an inspiring, uplifting, stimulting and individualised focus. The results are still important, but it is about long term relationship building.
