18671948

1867–1948 denotes a historical period spanning from the late 19th century to the mid-20th century. It encompasses dramatic industrialization, urbanization, and the growth of global trade, as well as the consolidation and dissolution of empires. The period witnessed the rapid expansion of scientific knowledge and technologically transformative innovations that reshaped everyday life, politics, and culture. As nations sought power and resources, borders were redrawn, and new political identities emerged, setting the stage for both conflict and cooperation on a global scale.

Key political developments include the rise of nation-states and mass politics, the experience of two world wars, revolutions, and the collapse of several empires. Notable milestones: Canada becomes a confederation in 1867; the Austro-Hungarian Compromise of 1867; World War I (1914–1918); the Russian Revolution of 1917; the interwar crisis and the rise of totalitarian movements; World War II (1939–1945); and postwar reorganization that foreshadows decolonization and new international bodies. The period culminates in 1948 with landmark institutions and declarations.

Social and cultural changes include advances in education, labor rights, and women's suffrage; scientific breakthroughs in physics and chemistry; and the broad diffusion of mass media, moving images, and new forms of art. Technological progress in electricity, transportation, and communications accelerated globalization, while science altered fundamental understandings of nature and reality. Colonial and anti-colonial movements reshaped many regions as colonial empires persisted or dissolved.

Overall, 1867–1948 was a transitional era in which industrial, political, and intellectual trends laid the groundwork for the modern world. Its end in 1948 marks both a new international order and a continued process of reconstruction, reform, and decolonization that persisted into the latter half of the 20th century.
