A state of anarchy（无政府状态） exists when a country has no effective government.
In an anarchy, there is nobody to make decisions or enforce the laws.
An autocracy（[ɔːˈtɑːkrəsi] 专制制度） is the simplest form of government.
In autocracy, the government is controlled by single individual, known as the autocrat（[ˈɔːtəkræt] 独裁者）.
Whether or not an autocracy is successful depends on the character and ability of the leader.
In an oligarchy（寡头政治 [ˈɑːləɡɑːrki]）, a small group of people controls the government.
Membership in this group often depends on family connections, wealth, or military power.
In a republic（共和国）, individuals are elected（选举） to represent the citizens.
The power of the government in a republic is limited by a constitution（宪法）.
A constitution is a written document that makes the rules for a government to follow.
This limits the power of the government.
A constitution defines the relationship between the government and its citizens.
