Gaius Cassius Longinus came from a very old Roman family, [[Cassia gens|gens Cassia]], which had been prominent in Rome since the 6th century BC. Little is known of his early life, apart from a story that he showed his dislike of despots while still at school, by quarreling with the son of the dictator [[Sulla]].<ref>[[Plutarch]], ''Brutus'', [https://penelope.uchicago.edu/Thayer/E/Roman/Texts/Plutarch/Lives/Brutus*.html#9 9.1-4]</ref> He studied philosophy at [[Rhodes]] under Archelaus of Rhodes and became fluent in [[Greek language|Greek]].<ref>[[Appian]], ''Civil Wars'', [https://penelope.uchicago.edu/Thayer/E/Roman/Texts/Appian/Civil_Wars/4*.html#67 4.67].</ref> He was married to [[Junia Tertia]], who was the daughter of [[Servilia (mother of Brutus)|Servilia]] and thus a half-sister of his co-conspirator [[Marcus Junius Brutus|Brutus]]. They had one son, who was born in about 60 BC.<ref>[[Plutarch]], ''Brutus'', [https://penelope.uchicago.edu/Thayer/E/Roman/Texts/Plutarch/Lives/Brutus*.html#14 14.4]</ref>
