Before the appearance of the Islamic state,the Arabs didn,t know
the organization or the right concept of administration.Also,the new
religion which was known by prophet Mohammad(peace by upon
him)was the first step for the administrative system i
n the Arabic
country.But this system was simple,rudimentary and proportional to
the new born Arabic country.After that,the righteous caliphs time
has evolved according to the requirements of public interest of the
country until it reach to the top of its development,and flourish in
theUmayyad period.However,after the transmission of the authority
to theUmayyads after they confound the other cultured people and
be affected by their politic and administration systems ,they
developed this system .So ,after they created and invented ,they put
bases for the administrative organization which became equal to
administration systems which was known to theRoman and
Persians.
