Explanation:

The fall of the Roman Republic relates to a long period of political instability and social unrest from around 134 BC. C. to 44 a. C., which culminated in the the advent of the Roman Empire and disappearance of the Roman Republic.

The definite dates of the crisis are unclear because "Rome has been oscillating between normality and crisis for many decades".

Likewise, the causes and characteristics of the crisis have changed over the decades, including forms of slavery, brigades, internal and external wars, land reforms, the invention of intolerable new punishments, the expansion of Roman citizenship, and even the changing composition of the Roman army.

Modern scientists also don't agree on the nature of the crisis. Traditionally, the expansion of citizenship (with all its rights, privileges, and duties) has been negatively assessed by Sallust, Gibbon, and others at their schools, as it has led to internal disagreements, conflicts with Rome's Italian allies, slave riots, and riots. However, other scientists have argued that the majority of the population, the poor and the disenfranchised cannot be accused of clearing up their legitimate and legal complaints since the Republic should be respublica.
