Abstract: Civil slavishness,traditional custom,absolutism theories by ideologists,meritorious great leaders as well as national wills which are suitable to autocracy,are all the causes for the occurrence and existence of autocracy.However,only three causes are the roots for autocracy,i.e.Asiatic mode of production,the single highest leader,and the human nature of the highest leader to seek the highest power.Regarding the roots and the various reasons for autocracy,autocracy is accidental,possible,and free-choosing under any circumstances,even under the circumstances that all the reasons for the autocracy exist.Autocracy is absolutely accidental,and is not absolutely and historically inevitable.

Key words: autocracy, absolutism, Asiatic mode of production, oriental absolutism
