Timelines of modern history

Timelines of modern history are timelines of events that happened in recent times. They often start at around the year 1900 and go up until today. Each year is marked on the timeline with important events written on it. Timelines help us understand what happened in the world in different years and in what order those events happened. They tell us about the history of the world and how it has changed over time. Timelines are often shown on a graph with time on one axis and the different events on the other axis. They help us connect what happened in one year to what happened in another. Looking at a timeline of modern history is like looking at a picture of the world and it's past.
