Why did the Caliphate system fail. Why did it not continue until
today. Don't you think we need one "just" leader for the whole
ummah (World Muslim Community) ?
Whilst individual caliphates had their shortcomings, after all we are
all human, as a ruling system it did not fail but was brought down
when the Young Turk movement was helped by outside powers to
conspire for its abolition. For more detail see the article:
Leadership is an essential requirement for any political order, and
whilst Islam is open to various models of governance, with differing
options for the authority, entitlements and obligations of the leader,
the checks on his power, the involvement of subordinates in various
decisions etc., there has to be an unambiguous command
structure for such an order to be effective, and at the present time,
with the Muslim entity divided into individual nation states, that is
not the case. Leadership, however, cannot be imposed, a leader
must emerge from his people by agreement.
