They speed up the development of the urban economy; and the urban class came into being and quickly became a strong strength. This laid a solid economic foundation and mass-base for the emergence of heresies. At the same time, The Roman church frequently used its economic and political privileges to grab the social wealth, and it seriously hindered the development of citizens. Citizen stratum began to carry out the heresy movement whose feature is against the privileges of Christian Church. Between the12th and13th century, the heresy movement turned into the peak. The heresy was not isolated, and it was a struggle that some class protected their own interests in the society Christianized.
