After Brutus, Cassius and other Senators stabbed and killed Julius Caesar, the people turned against them after a speech by Mark Anthony played up the magnanimity of Julius Caesar. They therefore fled Rome and raised armies rather than be captured.
In this except from Julius Caesar, they say their farewells to each other with the word, "everlasting" suggesting that this may be the last time that they would meet because should they die, there would be no other farewells.
