1900s

The 1900s (pronounced "nineteen-hundreds") was the decade that began on January 1, 1900, and ended on December 31, 1909. The Edwardian era (1901–1910) covers a similar span of time. The term "nineteen-hundreds" is sometimes also used to mean the entire century from January 1, 1900, to December 31, 1999 (the years beginning with "19"). The Scramble for Africa continued, with the Orange Free State, South African Republic, Ashanti Empire, Aro Confederacy, Sokoto Caliphate and Kano Emirate being conquered by the British Empire, alongside the French Empire conquering Borno, the German Empire conquering the Adamawa Emirate, and the Portuguese Empire conquering the Ovambo. Atrocities in the Congo Free State were committed by private companies and the Force Publique, with a resultant population decline of 1 to 15 million. From 1904 to 1908, German colonial forces in South West Africa led a campaign of ethnic extermination and collective punishment, killing 24,000 to 100,000 Hereros and 10,000 Nama. The First Moroccan and Bosnian crises led to worsened tensions in Europe that would ultimately lead to World War I in the next decade. Cuba, Bulgaria, and Norway became independent. The deadliest conventional war of this decade was the Russo-Japanese War, fought over rival imperial ambitions in Manchuria and the Korean Empire. Russia suffered a humiliating defeat in this conflict, contributing to a growing domestic unrest which culminated in the Russian Revolution of 1905. Unconventional wars of similar scale include insurrections in the Philippines (1899–1913), China (1899–1901), and Colombia (1899–1902). Lesser conflicts include interstate wars such as the Second Boer War (1899–1902), the Kuwaiti–Rashidi war (1900–1901), and the Saudi–Rashidi War (1903–1907), as well as failed uprisings and revolutions in Portuguese Angola (1902–1904), Rumelia (1903), Ottoman Eastern Anatolia (1904), Uruguay (1904), French Madagascar (1905–1906), Argentina (1905), Persia (1905–1911), German East Africa (1905–1907), and Romania (1907).
