Question

why is there modern art movement? how did its style differs from the previous art movement before modern era?

Answer 1

Explanation:

we can't put a definite reason to that but on paper it started with the painter's want for expressionism in their work

modern art is said to have started with Claude Monet's "First Sunrise". I attached it if you might find that interesting

The major difference in style was that modern art was based on representation by something that one can only imagine

while earlier art was based on realism
