Explanation:

During his presidency, Kennedy's approach toward civil rights was seen as one of lacking commitment. Black people were strongly discriminated, segregated and deprived from many rights and it took him a long time to take action on the subject. Until finally, in June, 1963, he communicated his intentions to make legislative changes regarding this subject, but five months later was assasinated.  

gaius cassius longinus and marcus junius brutus, former enemies of julius caesar who'd joined the roman senate, led caesar's assassination, dubbing themselves "the liberators." and the second one is   the assassination of julius caesar was the result of a conspiracy by many roman senators led by gaius cassius longinus, decimus junius brutus albinus, and marcus junius brutus. they stabbed caesar (23 times) to death in a location adjacent to the theatre of pompey on the ides of march 15 march 44 bc.
