The Intelligence Bureau (IB) is India’s oldest and most important internal intelligence agency.

It is responsible for collecting information, analysing threats, and helping the government maintain national security.

IB works under the Ministry of Home Affairs (MHA) and supports the police, armed forces, and government agencies by providing timely intelligence and security updates.

History and Establishment

The IB was originally created by the British Government in 1887 to prevent political uprisings and threats against colonial rule.

After getting established in 1887, the IB works mostly in secrecy and plays a vital role in protecting India from terrorism, espionage, cyber threats, and internal disturbances.

Later after independence, the Government of India reorganized the agency, and it became the country’s primary internal intelligence organization.

Today, the IB continues to operate quietly behind the scenes to safeguard the nation.
