One morning, toward the end of february 1848, i sat quietly in my attic-chamber, working hard . . . . when suddenly a friend rushed breathlessly into the room, exclaiming: "what, you sitting here! do you not know what has happened?" "no; what?" "the french have driven away louis philippe and proclaimed the republic!" according to the passage, which historical event made the author’s friend so excited? the defeat of the french army at waterloo the end of the congress of vienna the french revolution of 1848 napoleon iii’s election in 1848
