19101930

19101930 denotes the span of years from 1910 to 1930, a period historians often study as a bridge between late 19th‑ and early 20th‑century modernization and the harsher realities of the interwar era. It includes the final years of empires, a world war, and the beginnings of a new international order.

Political and military developments: The decade saw rising nationalism, technological change in warfare, and mass politics. The First World War (1914–1918) irreversibly altered borders and governance, leading to the collapse of the Austro-Hungarian and Ottoman Empires. In 1917–1918 Russia underwent revolution and civil conflict, while 1919–1920 treaties redrew Europe and the Middle East. The League of Nations, established in 1920, aimed to provide collective security and dispute settlement, though it faced sovereignty constraints and limited effectiveness.

Economic and social change: The 1920s included urbanization, industrial growth, and expanding consumer cultures in many nations, accompanied by social reforms and the extension of suffrage. The period also saw cultural innovations in art, music, film, and literature, and advances in science and technology, such as aviation, automobile use, and radio broadcasting.

End of era and transition: The 1929 stock market crash triggered the Great Depression, with lasting economic and political repercussions worldwide. In many countries, economic distress contributed to political extremism and social upheaval during the 1930s, shaping policies and conflicts that followed the 1910–1930 timeframe.
