who hatched the conspiracy?no links pls.pls answer fast

The conspiracy was being hatched for the past many days because Caesar’s non-stop unceasing ambition agitated the senators. Metellus Cimber, Casca, Cassius, Tremulous, and others. Metellus deliberately asked Caesar to grant permission for his brother, Publius Cimber's  return who has been banished from Rome by lawful decree. They were well aware he wishes would be refused. Metellus Cimber and others had anticipated that Caesar would deny and they shall use this unpleasantness and annoyance as an excuse to kill him.  Brutus had been convinced to join since it was the need of the hour as democracy was threatened. The conspirators feared that Caesar would become a dictator so they requested Brutus – the idealist to join them as he was a man of the masses.
