Intelligence History

The history of intelligence involves the development and use of information-gathering methods by governments and organizations to understand threats, inform decisions, and protect interests. It dates back thousands of years, with early examples like spies and messengers. Modern intelligence emerged in the 19th and 20th centuries alongside advances in technology, including signals interception, cryptography, and surveillance. Key moments include World Wars and the Cold War, which drove innovations in espionage, counterintelligence, and covert operations. Today, intelligence continues to evolve with digital technology, cybersecurity, and data analysis, playing a vital role in national security and global stability.
