The winner takes it all - also the course of history

From time to time there is this question appearing in my head, why everybody refers to Napoleon Bonaparte as "short", compared to his contemporaries.
Newer research actually found that Napoleons 160 something cm were around average in late 18th early 19th century France. So why is he still referred to as "short"?
It's not a secret that the story of events are being written by the winners. So, when Napoleon were defeated by the European alliance in 1815, they were the ones able to tell the tale of Napoleon 1st of France.

So, the fact is not that important, as long as the myth suits your agenda.

So, this only makes it harder to interpret the courses of history, and to create an accurate picture of the events that created the society we live in today. So is it possible to create an accurate and unbiased picture of history, and thereby today's society?

Hopefully, but not necessary.

Zee ya!
