The main changes were around the plebeian tribunes and the
plebeian council which were formed by the plebeian movement in its
first rebellion (the 1st plebeian secession). The council and the
tribunes were recognised, but the laws voted by the plebeian
council were not recognised as laws binding on all citizens,
including the patricians. Eventually they were recognised as
binding on all, and the plebeian tribunes became the main proposers
of laws and the plebeian council the main deliberative body. The
leaders of the plebeian movement gained access to all offices of
state, the senate and the priesthoods. These leaders were rich
plebeians who were co-opted into what became a patrician-plebeian
oligarchy with the help of liberal patricians who supported this
development. The rich plebeians then turned the backs on the poor
plebeians who had been the driving force of the plebeian movement.
The economic grievances of the poor plebeians were not addressed
properly.
