Sulla took charge of the constitution in 81 BC. All the power of the state would henceforth lay in the hands of the senate.The Tribunes of the People and the people's assemblies had been by the democrats to overthrow the senate. Tribunes were to be barred from all further office and the assemblies were deprived of the power of initiating any legislation. The senatorial control of the courts was restored at the expense of the equestrians.
There were to be no more repeated consulships, like those of Marius and Cinna.
Consuls were not to hold military command until, after their year of office, they went abroad as proconsuls, when their power could only be exercised in their respective province.
Then in 79 BC Sulla lay down his powers as dictator and devoted his remaining months to the enjoyment of wild parties. He died in 78 BC.
Although the Roman Republic technically still had some fifty years to go, Sulla pretty much represents its demise. He should stand as an example to others to come that is was possible to take Rome by force and rule it, if only one was strong and ruthlessness enough to do what ever deeds were required.
