Answer:
The end of empire
Explanation:
At the end of the 19th and the beginning of the 20th century Europe went through political (ideological) and social turmoil as a consequence of the decline and fall of the classical empires, such as the Habsburg empire. Ideologies emerged like liberalism, conservatism and socialism.
This triggered off a cultural change known as modernism: for example expressionism and surrealism in art; functionalism in architecture; abandoning tonality in music; the break with tradition in literature etc.
