English part of Serbian history
Significant written sources from the Serb history regarding intelligence-security activities date from the period of rule of Czar Dusan. "Dusanov zakonik" (Czar Dusan's Code) is the first historically significant legal document in which a description of such activities can be perceived. Relying on the Byzantine experience, Czar Dusan introduced as many as 70 different titles into the administrative structures of his rule, some of which were connected with intelligence-security activities.

Here is the part of Serbian history From the First Serbian Uprising (1804) up to World War I (1914)
The development of modern security, and in certain forms, intelligence activities on the territory of Serbia, dates from the beginning of the XIX century, namely immediately prior to and during the First Serbian Uprising.

In 1804, at the very beginning of the First Serbian Uprising, the willingness of the rebels to engage in the development of intelligence activities was not evident, especially regarding the organizing of data gathering concerning Turkish intentions and plans. Intelligence work was primarily focused on the military-political segment of the uprising, and the military and civil sectors were not essentially separated. All information regarding Turkish intentions and movements were obtained from war prisoners and civilians coming from areas controlled by the Turkish governors. First examples of double-play, i.e. the re-recruiting of Turkish agents, originate from this period.

Great importance was given to the internal security of the uprising and every incidence of compromise and cooperation was cut down at the roots. Betrayal, defeatism and espionage were, from the very beginning, considered as extremely grave criminal acts and were, as such, severely punished. During the First Serbian Uprising, in the scope of intelligence-security activities, misinforming emerges and it is aimed at deceiving the Turkish population. For the purpose of strengthening the uprising, the rebels were giving different information, primarily for propaganda-mobilization purposes.

The first official document from the time of Karadjordje, significant for the development of intelligence-security activities, is the "Nacertanije" from March 1810. The first article of this document, for the first time, separates police and military work, and establishes the position of "Head of the Police" responsible to the "Popeciteljstvo" (Ministry), and superior to the so-called "liktors" - assistants for the interior, foreign and secret service. In late 1810, as a result of conflicts with some of the Dukes and his desire to strengthen his authority, Karadjordje set in motion an initiative concerning a new session of the Parliament, with the aim to overcome piled up problems between the most prominent Serbian leaders. One of the most significant results of Parliament activities, which held its session in January 1811, was the founding of six Popeciteljstva (Ministries), including the "Popeciteljstvo vnutreni dela" (Ministry of Interior) where Jakov Nenadovic was appointed Minister - the first Serbian Minister of Interior. Apart from ensuring the respect of legality in the work of state bodies, combating haiduk activities (anti-Turkish highwaymen), ensuring the control of roads and crossings, and the sustaining of public law and order, the jurisdiction of the Minister included other activities in the field of state security.

These were the largest accomplishments regarding the organizing of the state administration and the activities of public and state security, since the unsuccessfulness of the First Serbian Uprising marked the collapse of all attempts made by the Serbs to establish, in a more serious manner, state administration bodies in relation to the Central Turkish Government.

In the period of his first rule (1815 - 1839), Prince Milos Obrenovic gave significance to the organizing of intelligence-security activities, in view of the circumstances prevailing at that time and the way in which he came to power. The main task of the bodies in charge of implementing activities from the filed of intelligence-security work, was to secure the rule of Prince Milos, both from the Turks and other foreign political and military factors, and from internal opponents.

From 1830, Prince Milos organizes his rule in compliance with strict centralistic principles. Only then began the organizing of administrative institutions, courts and other state institutions. Intelligence-security bodies at the time of Prince Milos controlled every aspect of social life, they were engaged in all political and administrative activities, they were occupied with the economical aspect of life in Serbia, with the functioning of medical care, education, the press, the Church, the traffic etc. Apart from the internal political life of the country, intelligence activities were also directed at the foreign policy of Serbia of that time.

An important year for the further development of intelligence-security activities in the territory of Serbia up to 1914 was the year 1862 when a centralized state administration in the Principality of Serbia was established, having seven newly formed ministries, including the Ministry of Interior. Apart from public security, the Ministry of Interior was in charge of activities which may be classified as intelligence-security activities based on worldwide experience regarding the development of state security work. By subsequent amendments of the organization of the central state administration, the Department for Confidential Police Work was formed within the Ministry of Interior, responsible for the maintaining of the internal social order and the overall security of the country. This represents a second serious attempt to form civilian intelligence-security bodies in Serbia. After this attempt, it was not until the end of World War I that systematic solutions in this significant field of state administration were reached.
