Observations on the History of Oil Painting

Who have been the major players throughout the history of oil painting? Why is this so?
I think Van Gogh, Picasso, Andy Warhol all were very important because they all made major statements through their art and revolutionized the meaning of art. But more specifically white men have been the major players through out the history of oil painting. I believe this is so because white men through out history have had more opportunities and have been more privilaged than nonwhites.

Who seems to be missing from the history of oil painting? Why is this so?
I believe that non white people are missing from the history.

Where in the world did most oil painting taking place?
Most oil painting took place in Europe and the US.

Where did all these oil paintings go? Why? How does where these paintings “live” affect who learns about them and why?
They are in some museums in Europe. and these paintings affect Europeans because they will become use to the idea of using oil paints and they will either form a love or dislike for it.

How has subject matter changed over time? Why?
im not sure if it has changed, but it has definitely expanded. I think people have become more creative with their ideas and used prior paintings to influence their works of art.
