N/A (Legislative Response)	1870	Section 124A of the Indian Penal Code (Sedition Law) was introduced, criminalizing speech or writing that brought or attempted to bring into hatred or contempt, or excited or attempted to excite disaffection towards the Government established by law in British India.	This law became a primary tool for suppressing nationalist writings and speeches, including those of revolutionaries. It was used to prosecute numerous leaders and journalists, effectively curtailing freedom of expression and assembly, and was a constant threat to any form of dissent, violent or otherwise.
N/A (Legislative Response)	1908	The Explosive Substances Act was enacted, making it a criminal offense to possess or manufacture explosive substances with unlawful intent. The Criminal Law Amendment Act was also passed, allowing for summary trials and special tribunals for political offenses, including those related to revolutionary activities.	These acts were direct responses to the surge in bomb-making and political violence, particularly in Bengal. They provided the British government with enhanced legal powers to swiftly prosecute revolutionaries, bypassing normal judicial procedures and imposing harsher penalties, thereby crippling their operational capabilities.
N/A (Legislative Response)	1915	The Defence of India Act was passed during World War I, granting the government extraordinary powers to curb civil liberties, including detention without trial, censorship, and control over publications. It was primarily aimed at suppressing the Ghadar movement and other revolutionary activities during wartime.	This act provided the British with sweeping powers to deal with any perceived threat to national security, effectively suspending many civil rights. It was used extensively to arrest, detain, and try Ghadarites and other revolutionaries, severely disrupting their plans for armed insurrection during the war.
N/A (Legislative Response)	1919	The Anarchical and Revolutionary Crimes Act, popularly known as the Rowlatt Act, was passed, allowing the government to imprison any person suspected of terrorism for up to two years without trial, and giving the police the power to search a place without a warrant.	This act was a direct response to the recommendations of the Sedition Committee (Rowlatt Committee) to counter the revolutionary threat. It was widely condemned as 'no vakil, no appeal, no daleel' (no lawyer, no appeal, no argument) and sparked widespread protests, including the Jallianwala Bagh massacre, demonstrating the British government's determination to crush dissent at any cost.
