18731924

1873–1924 refers to a historical interval spanning the late 19th and early 20th centuries. The span begins in 1873, a year marked by a global financial crisis that ushered in a longer period of economic adjustment in many regions. The era is defined by rapid industrialization, urbanization, and the expansion of railways and electricity, alongside significant social and political reforms that reshaped governments and economies.

During this period, the world experienced the height of the Second Industrial Revolution, with advances in steel, chemicals, telecommunications, and manufacturing. Imperialism and competition among great powers intensified, helping shape global trade and colonial structures. Urban culture and new ideas in science and the arts challenged traditional norms, contributing to movements such as modernism.

Key historical events include the Russo-Japanese War (1904–1905), the revolutions and reform movements of the early 1900s, and World War I (1914–1918). The war brought about profound political upheaval, revolutions in Russia (1917), and the collapse or transformation of several empires. The postwar period saw new international arrangements, including the Paris Peace Treaties (1919) and the creation of the League of Nations, along with shifts in borders and governance.

In science and culture, this era witnessed advances in physics, psychology, and the arts that helped redefine knowledge and expression. The formation of the Soviet Union in 1922 and the death of Vladimir Lenin in 1924 marked turning points in global politics. By the mid-1920s, many societies were transitioning from wartime economies to new forms of political and economic organization, setting the stage for further upheaval and transformation in the interwar years.
