Abstract: The history of tolerance develops along with the history of intolerance. The hum an desire to survive in primitive society made autocracy some kind of a necessit y when tolerance was not known to people. In the city-state era, tolerance slow ly infiltrated into people's political life. Because of the multi-gods worship, the tolerance first got the meaning of the original "freedom". While in the m iddle ages, people were panic-stricken when they heard of religion Magistrates and the publication examination was grave to the extreme but the value of tolera nce was not denied. On the contrast, it had already developed silently. "Tolera nce" in the modern political sense derives from religious tolerance in the 16th and the 17th centuries, and forms the basic principles and standards for tolera nce. Today, tolerance has gone through two major historical changes: one in the private sphere, and the other in the field of international relations.
