text: when are the ides of march? and what did caesar say to the roman senate? i think you are speaking in context of shakespears work,  ceasar was there to discuss the banishment of mettulus's brother, he was rather rude in all of this and full of himself throughout the play, cocky. caesar was a member of a oligarcy of small group of equal rulers.  after he proceed to wage war and defeat them he was sole leader or the roman empireor dictator for life.... where the term czar or kaiser came from......  this is what prompted the senators to go ahead with execution plans in 44bc.     now the ides of march as you have seen above for simplicity sake is generally accepted at the 15th of march.  the term comes from roman mythos which gaves names to the 1st(kalends  -spelling anyone?, 7th (nones)and middle (ides)days of the month.  the calender was supposedly created by the founders of rome romulus and remus.  the rest of the days were described by counting days from or to one of the above days.... example ides of march and five days would be the 19th of march.... think roman numerials.   now some months the ides fell on the thirteenth of the month.  now this term was used all the way until shakeperes time fluently probably due to the classical nature of roman literature.  now it is familar due to shakesperes work.
