Riddles...just for the heck of it :3

--------------------
Over the centuries Ive conquered kingdoms and united nations.
alot of hearts and emotions.

Although my forfathers were cold, brute and sinful.
Im different, in all ways possible.
Yet, these days I do more than just conquering.
I create and invent things

Without me, history wont be reality.
It will be just a mere memory
of the things that are used to be.

My conquering character won't fade
Even if I change by time, by style, my colour or my shape.
May I riddle you who I am?
The object used by men.
Take notes of the hints you see
The answer to this riddle and me.
