In this article, the authors describe the way that leadership research has dramatically changed over the last 30 years and how leadership development programs have not kept pace with some of the important changes. In particular, the authors propose that five revolutionary leadership concepts have been overlooked and should be included in future programs. The five areas described are: educating non positional leaders and fostering empowerment, abuses of leadership power, grassroots leadership, context and cultural leadership, and the spiritual and emotional dimensions of leadership.
