it was named after Sir sidney rowlatt.
it was called black bill or black act by indians who protested against it
it gave british more power over indians
according to the act people could be tried in private by 3 high court judges
there was no right to appeal
people could be made to live in particular place
people could be arrested without warrant
could be kept in prison without trial.
jinnah and other indians resigned from imperial legislative council and angry protests began, cuz indians didnt approve of this act. strikes were organised throughout india, and Gandhi began his non-cooperation movement, people joined and huge demonstrations and processions were held
this happened cuz indians who served brits in WWI thought british would reward them with self-rule, instead they established control more firmly, indians felt betrayed hence protested
the passing of the act, led to mad protests which led to JALLIANWALA BAGH INCIDENT
