Riot between two communities or ethnic groups is not a new feature. It occurs mainly due to the following reasons:
1. Socio-economic condition,
In the year 1921-22, communal jealously did not subside.The Muharram Celebrations had bee attended by serious riots both in Bengal and in the Punjab. In the latter province in particular, communal feeling at Multan reached very serious heights, and although the casualty list was comparatively small, a great deal of property was done.
Though the year 19222-23 was a peaceful year the relations between the two communities were strained throughout 1923-24. But in no locality did this tension produce such tragic consequences as in the city of Kohat.
