History is the study of what happened in the past. At the moment generally everything that happened during the 20th Century and before is history while what happened from the start of the 21st Century to the present is Geography or Current affairs.
Those who cannot remember the past are condemned to repeat it 
The rise of far right now, for example, is very similar to the rise of the right in Europe before the World War II. Sometimes we can learn from the past but other times conditions have changed so much that history cannot repeat itself.
