Leadership is governed by over 66 theories which leaves many leaders and leadership scholars searching for an inclusive leadership theory. The existence of too many leadership theories obstructs progressive practice and research of leadership, hence there is need for leadership theory consolidation. This paper is an attempt to integrate leadership theories. The integration efforts are based on representative leadership theories and the review of the wider relevant leader-ship literature. Initially, the integration was to be built around 66 leadership theories but with further study 44 theories were eliminated to avoid either repetition or miniature issues and it was established that the 22 leadership theories are a good representation of the concepts captured in leadership theories. The review of the 22 leadership theories was enriched with insights from the wider leadership literature. The review and synthesis of leadership theories and the wider relevant leadership literature revealed that leadership is built on six (6) foundational domains, namely: character, characteristics, people practices, institutional practices, context and outcomes (CCPICO). The six domains occasioned the development of an integrative leadership model: ethical and effective leadership (EEL). As a consequence of the EEL model, one, the EEL subdomains are highlighted, two, leadership development based on EEL model is proposed, three, leadership definition that is in line with EEL model is suggested.
