Early dictatorships

Dictatorship is historically associated with the Ancient Greek concept of tyranny, and several ancient Greek rulers have been described as "tyrants" that are comparable to modern dictators. The concept of "dictator" was first developed during the Roman Republic. A Roman dictator was a special magistrate that was temporarily appointed by the consul during times of crisis and granted total executive authority. The role of dictator was created for instances when a single leader was needed to command and restore stability. At least 85 such dictators were chosen over the course of the Roman Republic, the last of which was chosen to wage the Second Punic War. The dictatorship was revived 120 years later by Sulla after his crushing of a populist movement, and 33 years after that by Julius Caesar. Caesar subverted the tradition of temporary dictatorships when he was made dictator perpetuo, or a dictator for life, which led to the creation of the Roman Empire. The rule of a dictator was not necessarily considered tyrannical in Ancient Rome, though it has been described in some accounts as a "temporary tyranny" or an "elective tyranny".

Asia saw several military dictatorships during the post-classical era. Korea experienced military dictatorships under the rule of Yeon Gaesomun in the 7th century and under the rule of the Goryeo military regime in the 12th and 13th centuries. Shoguns were de facto military dictators in Japan beginning in 1185 and continuing for over six hundred years. During the Lê dynasty of Vietnam between the 16th and 18th centuries, the country was under de facto military rule by two rival military families: the Trịnh lords in the north and the Nguyễn lords in the south. In Europe, the Commonwealth of England under Oliver Cromwell, formed in 1649 after the Second English Civil War, has been described as a military dictatorship by its contemporary opponents and by some modern academics. Maximilien Robespierre has been similarly described as a dictator while he controlled the National Convention in France and carried out the Reign of Terror in 1793 and 1794.

Dictatorship developed as a major form of government in the 19th century, though the concept was not universally seen pejoratively at the time, with both a tyrannical concept and a quasi-constitutional concept of dictatorship understood to exist. In Europe it was often thought of in terms of Bonapartism and Caesarism, with the former describing the military rule of Napoleon and the latter describing the imperial rule of Napoleon III in the vein of Julius Caesar. The Spanish American wars of independence took place in the early-19th century, creating many new Latin American governments. Many of these governments fell under the control of caudillos, or personalist dictators. Most caudillos came from a military background, and their rule was typically associated with pageantry and glamor. Caudillos were often nominally constrained by a constitution, but the caudillo had the power to draft a new constitution as he wished. Many are noted for their cruelty, while others are honored as national heroes.
