Examples of autocratic leadership styles are dictatorships and absolute monarchies. An autocratic leadership style is exemplified in a system where the majority of decisions are made by a single person, with little to no input from anyone else. Autocratic leaders make exclusive decisions about policies and procedures, and typically are in complete command of those they have authority over.
A ruler of a nation who makes all of the country's decisions, including those concerning judicial, financial and religious matters, is an autocratic ruler. Similarly, a company president who makes all of the decisions about the company's operations from budget to employee policies is an autocratic leader.
The downside of this leadership style is that it is very easy for autocratic leaders to abuse their powers. Because they have virtually all control of the decision-making processes, their influences have very few limitations, and the only way for them to be replaced is for a majority to rise up against them.
However, there are some benefits to an autocratic leadership style. The decision-making process is much faster because few, if any, people must be consulted in making decisions. When time is of the essence, this is a positive. Autocratic leadership is also good for task-oriented situations when it is in the best interests of the group for each individual to be able to focus on their own tasks.
