Which is the oldest intelligence agency of Pakistan, established even before the country’s independence?

The Intelligence Bureau (IB) is the oldest intelligence agency of Pakistan, established in 1947, right after independence. However, its roots go back to 1885 in British India, where it was originally created to monitor political movements against colonial rule. After the partition, IB was inherited by Pakistan and became the country’s first civilian intelligence agency. Today, it plays a central role in domestic intelligence, counter-espionage, and internal security matters. This information is frequently tested in Pakistan Studies MCQs, as it highlights the historical background of Pakistan’s key institutions.
