Final answer:
Brutus intended his speech at Caesar's funeral to justify the assassination as a defense of the Republic and to garner public support for the conspirators' actions against perceived tyranny.
Step-by-step explanation:
Brutus' intention for giving his speech at Caesar's funeral was to justify the assassination of Caesar to the Roman public and to establish the reasons behind the conspirators' actions. He aimed to present the assassination as a patriotic act carried out to protect the Roman Republic from Caesar's perceived ambition and dictatorial tendencies. By doing so, Brutus sought to maintain public order and support for the conspirators' cause, hoping to convince the citizens that the assassination was necessary for the greater good and to prevent the establishment of a tyranny that would dismantle the republic's values and institutions.
