Reasons for Start:
The Indian %%Muslims wanted to keep the Khilafat alive%%.
They had a special respect for the Turkish/Ottoman Empire as the %%Sultan of Turkey was also the spiritual head or Khalifa of the entire Muslim world.%%
Finally the Indian Muslims had long been developing fears about the British policy towards them not only in India but in other parts of the world, too.
Reasons for Failure:
The Movement was %%not well organized.%%
%%In August 1920, about 18,000 Muslims left for Afghanistan%% after %%selling their properties%% and %%leaving their jobs%% after their leaders %%had declared India as Dar ul Harb/a land under the enemy rule.%%
Finally, the last nail in the coffin of the Khilafat Movement was driven by the %%Turkish Military leader Kemal Attaturk%% (Mustafa Kemal Pasha).
