It is impossible to answer this question in its current form, because you are requesting information about more than one hundred years of history without narrowing it to a certain part of the world, or focusing on a certain country. There were different events in US history, for example, as opposed to British history, or French history, or Chinese history.
Some of these events affected many countries at the same time, such as two world wars, both of which occurred in the twentieth century-- the first, beginning in 1914, and the second developing gradually during the 1930s and entered by the USA in 1941. But in addition to wars, there were numerous developments and advances in communication, transportation, and science. From the late 1840s on, new inventions (the telegraph, the telephone, Photography, radio) changed life in a number of countries as well.
