The Seditious Meetings Act was passed in 1907 during the British Raj in India. This act was enacted to suppress the growing Indian nationalist movement. The act prohibited public meetings of more than 20 people without prior permission from the authorities. The act also restricted the freedom of speech and assembly of the Indian people.

2. Indian Press Act:
The Indian Press Act was passed in 1910. This act gave the British government the power to censor and control the press in India. The act also required newspapers to obtain government permission before publishing any material. The Indian Press Act was another attempt by the British government to suppress the growing Indian nationalist movement.

3. Explosive Substances Act:
The Explosive Substances Act was passed in 1908. This act was enacted to control the manufacture, possession, and use of explosive substances in India. The act was passed in response to the increasing use of explosives by the Indian nationalist movement. The act made it a crime to possess or use explosive substances without a license.

The Annulment of Partition refers to the revocation of the partition of Bengal in 1911. The partition of Bengal was a controversial move by the British government to divide the province of Bengal into two separate entities. The move was seen as an attempt to weaken the Indian nationalist movement. However, the partition was annulled in 1911 due to widespread protests by the Indian people.
