I cant remember but who was the man to reform the holy roman empire for the second time?

Answer 1

I believe you are thinking of Emperor Frederick III. He instituted a series of laws that gave the individual Dukes of the empire more say in government. These were known as the Reichsreforms.

Answer 2

i believe it was fredrick I "Barbarossa" but Conrad III started it all
read the following if you want more info.


Conrad III came to the throne in 1138, being the first of the Hohenstaufen dynasty, which was about to restore the glory of the Empire even under the new conditions of the 1122 Concordat of Worms. It was Frederick I "Barbarossa" (king 1152, Emperor 1155–1190) who first called the Empire "holy", with which he intended to address mainly law and legislation.

Also, under Barbarossa, the idea of the "Romanness" of the Empire culminated again, which seemed to be an attempt to justify the Emperor's power independently of the (now strengthened) Pope. An imperial assembly at the fields of Roncaglia in 1158 explicitly reclaimed imperial rights at the advice of quattuor doctores of the emerging judicial facility of the University of Bologna, citing phrases such as princeps legibus solutus ("the emperor [princeps] is not bound by law") from the Digestae of the Corpus Juris Civilis. That the Roman laws were created for an entirely different system and didn't fit the structure of the Empire was obviously secondary; the point here was that the court of the Emperor made an attempt to establish a legal constitution.

Imperial rights had been referred to as regalia since the Investiture Controversy, but were enumerated for the first time at Roncaglia as well. This comprehensive list included public roads, tariffs, coining, collecting punitive fees, and the investiture, the seating and unseating of office holders. These rights were now explicitly rooted in Roman Law, a far-reaching constitutional act; north of the Alps, the system was also now connected to feudal law, a change most visible in the withdrawal of the feuds of Henry the Lion in 1180 which led to his public banning. Barbarossa thus managed for a time to more closely bind the stubborn Germanic dukes to the Empire as a whole.

Another important constitutional move at Roncaglia was the establishment of a new peace (Landfrieden) for all of the Empire, an attempt to (on the one hand) abolish private vendettas not only between the many local dukes, but on the other hand a means to tie the Emperor's subordinates to a legal system of jurisdiction and public prosecution of criminal acts – a predecessor concept of "rule of law", in modern terms, that was, at this time, not yet universally accepted.

In order to solve the problem that the emperor was (after the Investiture Controversy) no longer as able to use the church as a mechanism to maintain power, the Staufer increasingly lent land to ministerialia, formerly unfree service men, which Frederick hoped would be more reliable than local dukes. Initially used mainly for war services, this new class of people would form the basis for the later knights, another basis of imperial power.
