Many horrific catastrophes have rocked the world and shaped history forever. However, some of these events were apparently worse than initially perceived. A Reddit question recently went viral ...
A timeline is a list of events displayed in chronological order. [1] It is typically a graphic design showing a long bar labelled with dates paralleling it, and usually contemporaneous events.
