There are many ways
the policies and achievements of Muhammad's successors helped the Arab world.
One of the main achievement was to unite the Arab under one flag instead of
various tribes and communities, as the successors of Muhammad used the term
"Khalifa" which was considered a unanimous leader of all the Muslims
thus any territory that came under Islamic rule or any people who accepted
Islam were united behind "Khlifa" instead of various leaders and
tribal heads.<span>
As there was a central system established in that time of
succession, more focus was placed on developmental structures. For example in
the time of Umar, the second successor various facilities were built for the travelers
and those out on the road.
<span>Trade and commerce evolved due to peace and stability
provided by the central government as opposed to earlier times when caravans
were looted in other tribal territories. </span></span>
Russia’s heavy losses in WWI quickened existing calls for a political revolution against the tsar, as corruption and economic stagnation left millions of Russians in misery. By contrast, America’s economy was booming during the same period, largely due to a system of free enterprise. Political “radicalism” and especially Russian “Bolshevism,” then, were seen as unnecessary and dangerous.
The first one was made from the Clergy, the second one was from the Nobility, and the last one is from the Commoners.
A thief snitched on them.
