Step-by-step explanation:
Important Occurrences during the Modern Period
The Modern Period is marked by a series of transformative events with far-reaching effects on society, art, and politics. Two particularly important occurrences are the Industrial Revolution and the series of political upheavals culminating in the Russian Revolutions. The Industrial Revolution, starting in the late 18th century, revolutionized the basic aspects of society such as clothing, food, and transportation, transitioning the world from agricultural bases to industrially and urban centers. During the early 20th century, the Russian Revolutions led to the downfall of the Russian monarchy and the rise of the USSR, including the Bolshevik Revolution, which signified a major shift in political paradigms of the time.
These events influenced not only the economic and political landscapes but also led to significant cultural changes. Modernism, beginning with the Realist Movement and spanning until Abstract Expressionism, questioned traditional norms and embraced progress and innovation across arts and philosophy. Writers, artists, and thinkers throughout this period often demonstrated a sense of disillusionment with established structures while seeking new ways to express the rapidly changing reality of their times.
