Final answer:
An autocratic leader rules with a dictatorial style, issuing orders with minimal input from group members, focusing on meeting goals through a top-down communication structure.
Step-by-step explanation:
The type of leader who governs a group with a dictatorial style is autocratic. An autocratic leader, also known as an authoritarian leader, issues orders and assigns tasks with little to no feedback from group members. These leaders are focused on meeting goals and often have a top-down communication pattern.
An autocratic leadership style contrasts with a democratic leader who encourages group participation and consensus building, although this can be time-consuming and potentially create factions. A laissez-faire leader, on the other hand, is very hands-off, allowing group members to make their own decisions, which can be beneficial in a setting with highly motivated individuals but risks lack of progress otherwise.
