Autocratic Governments in Ancient Rome
The sole rule of the king was replaced in the Roman state around the 6th century B.C. (in the context of the efforts of the city of Rome to gain independence from Etruscan rule) by the republic, in which the city nobility (patricians) initially possessed state power, in which the lower strata of the Roman citizenry (the "people") later also participated.
In times of war and crisis in the Roman Republic there was the possibility of appointing a dictator with very far-reaching powers for six months. This dictator held the summum imperium, i.e. all offices of the magistrate were under his control (for a limited period of time). The powers of the tribunes of the people were suspended during the dictatorship, as was the right of Roman citizens to appeal to the criminal courts. The dictator, however, was not allowed to change the constitution or declare wars or levy new taxes. He could not himself be prosecuted for acts committed while in office. A comparable "sacrosanct" (Latin sacrosanctus, "inviolable") position was otherwise only held by the tribunes of the people as specially protected representatives of the people. The Roman dictatorship can hardly be equated with dictatorial regimes of the modern era, since it was a legitimate institution that was limited in the extent and duration of its power. In the late period of the Republic, however, it was increasingly in danger of being misused for despotic purposes by individual political actors. Thus, shortly before his assassination, Caesar is said to have attempted to have a lifelong dictatorship bestowed upon him.
When the principate was founded in the imperial period, the rights and powers of the tribunes of the people in particular were transferred to the princeps ("first", from which the titles prince and prince arose), who functioned as an unlimited autocrat and used the titles Augustus and Caesar (from which: emperor). The appearance of an exceptional government acting in the sense of the republican state constitution was preserved. The title Imperator ("commander", actually the honorary title of a military commander), which was also used by most Roman emperors, corresponded to the term Autokrator ("autocrat") in the Greek imperial titulature, which was used parallel to or instead of the Latin designations, especially in the later phases of the Roman Empire.
Autocratic governments in Russia
In the Russian Empire, from 1721 onwards, the tsar officially bore the title of autocrat for a long time and called himself the "Autocrat of All the Russias" (Russian Император и Самодержец Всероссийский Imperator i Samodershez Vserossiysky, literally "All-Russian Emperor and Autocrat"), i.e. "autocrat of all Russia". The form of government of the Russian tsars since the abolition of the ecclesiastical patriarchal office by Tsar Peter I is also known as Caesaropapism. Although the secular ruler did not directly unite secular and spiritual power in one person, the church was directly subordinate to the state authorities.
After the Russian Revolution and the introduction of the Soviet system, this was realized in the form of autocratic rule by the Communist Party, as it came to fruition in particular in the constitution of the Soviet Union in force from 1936 to 1977.
