Lots of people can consider historical fact and events that happened in the past as the same thing. To be honest I have never thought about that as two completely different things. After lecture and my own consideration, I am surprised that there is a huge difference between both.
When I hear “historical fact” I have in my mind something what was or happened in a time and space. It is also something which is put in a right time and place and has a historical base. Regarding to “something that happened in the past” I can tell that it may be accurate, but we do not take it to be fact. It might be considered as all things which happened before right new. Everyone can refer to the same thing which had place in the past, but every single person may remember different things which are important to he/she.
Some facts about the past are recorded and remembered because they have meaningful influence on development of historical occurrence, they had an importance for the history process. Some of them could focus of the history of mankind. Other may not be considered worthy of committing to memory because concern only small groups or individuals.
