The names of the most famous and dangerous intelligence agencies in the world, such as the KGB, Stasi, CIA, and Mossad, are familiar to many. In its time, one of the strongest was the Romanian Securitate, founded by the descendant of Russian emigrants, Mikhail Nikolaevich Moruzov. He began his career in the police, but due to his business qualities and analytical mind, he quickly advanced in service. During World War I, Moruzov transitioned to military intelligence and actively operated, identifying 156 German and Bulgarian agents. A particular success was the exposure of a group of Soviet Bolsheviks attempting to spread counterfeit currency in Romania. After this, Moruzov became the leading counterintelligence officer in the country.

In 1924, he headed the new special service, Securitate, which means 'security.' Thanks to a wide network of informants, Mikhail Nikolaevich quickly obtained the necessary information and even recruited several agents from British MI-6 and German counterintelligence. Moruzov was an advocate of technological progress and recommended his staff use phone tapping and audio recordings. His office was equipped with one-way mirrors for covert observation of visitors. He also did not shy away from gathering compromising material on high-ranking officials.

The greatest activity of the Romanian counterintelligence occurred in the late 1930s. By this time, Moruzov had acquired many enemies, among whom the members of the pro-fascist organization 'Iron Guard' were particularly dangerous. In 1940, when Marshal Antonescu came to power, entering into an alliance with Hitler, a hunt for undesirable individuals began. Mikhail Nikolaevich did not manage to escape, was arrested, and later killed in prison. However, the intelligence network he created continued to function, identifying spies until the end of the 1940s.
