On 30 July 1912 the Meiji Emperor died and on that day the Taisho era commenced. Emperor Taisho, of weak mental and physical health, had none of the charisma of his father. This marked the end of an era, during which Japan had exerted herself to the utmost of her strength in order to catch up with the western powers. In February 1913, the military-clique-led cabinet was forced to resign, for the first time in Japan's modern history, by popular protest from both inside and outside the Diet. This led to the emergence of a male suffrage movement and the vague term ‘Taisho democracy’, and eventually to the formation of a party-led cabinet with the first common people premiership, Kei Hara. Indeed, because of rising prices, there were serious rice riots in 1918. In international relationships, Japan, with the Anglo- Japanese Alliance still in place, played a modest part on the Allied side in the First World War. The Japanese military, backed by strong anti-western right-wing activists, increasingly showed aggression by taking the opportunity of fishing in troubled waters in China and elsewhere. Shortly after the declaration of war against Germany in August 1914, the Japanese military took over the German territories on the Chinese mainland and presented to the Chinese the notorious Twenty-One Demands. The Russian Revolution of 1917 induced Japan, in co-operation with the western powers, to intervene in Siberia, which extended until 1925. The Taisho era, of less than fourteen years, was a period of tension, but at the same time there was an astonishingly rapid growth of the economy which produced a prosperous banking sector.
