This chapter has reviewed modern theories of leadership, discussing and outlining various definitions of leadership. The results of the literature review indicate that traditional leadership behaviors that work in a proximate environment may encounter challenges in a virtual setting. Followers exposed to little face-to-face contact require empowerment by supervisors and subsequently a higher degree of selfleadership. Reviewing theory on distance leadership it became clear that no grounded definition of distance leadership existed. In addition to a vague understanding, distance leadership links disciplines of leadership theory with communication theory and vertical dyad-linkage theory. In the course of the review, Full Range Leadership has been identified as the most prominent theory in current leadership research. According to the work of many researchers, three distance dimensions have shown to be the potentially main influencers of the leader-follower relationship: physical distance, relationship quality, and interaction frequency. These parameters serve as subjects of interest to the following hypotheses.
