  Many countries jailed those who spoke out against the conflict. These included Eugene Debs in the US and Bertrand Russell in Britain. In the US, the Espionage Act of 1917 and Sedition Act of 1918 made it a federal crime to oppose military recruitment or make any statements deemed "disloyal". Publications at all critical of the government were removed from circulation by postal censors, and many served long prison sentences for statements of fact deemed unpatriotic.
  
  Several nationalists opposed intervention, particularly within states that the nationalists were hostile to. Although the vast majority of Irish people consented to participate in the war in 1914 and 1915, a minority of advanced Irish nationalists had staunchly opposed taking part. The war began amid the Home Rule crisis in Ireland that had resurfaced in 1912, and by July 1914 there was a serious possibility of an outbreak of civil war in Ireland. Irish nationalists and Marxists attempted to pursue Irish independence, culminating in the Easter Rising of 1916, with Germany sending 20,000 rifles to Ireland to stir unrest in Britain. The British government placed Ireland under martial law in response to the Easter Rising, though once the immediate threat of revolution had dissipated, the authorities did try to make concessions to nationalist feeling. However, opposition to involvement in the war increased in Ireland, resulting in the Conscription Crisis of 1918.
  
  Other opposition came from conscientious objectors —some socialist, some religious—who had refused to fight. In Britain, 16,000 people asked for conscientious objector status. Some of them, most notably prominent peace activist Stephen Hobhouse, refused both military and alternative service. Many suffered years of prison, including solitary confinement. Even after the war, in Britain, many job advertisements were marked "No conscientious objectors need to apply".
  
  On 1–4 May 1917, about 100,000 workers and soldiers of Petrograd, and after them, the workers and soldiers of other Russian cities, led by the Bolsheviks, demonstrated under banners reading "Down with the war!" and "all power to the Soviets!". The mass demonstrations resulted in a crisis for the Russian Provisional Government. In Milan, in May 1917, Bolshevik revolutionaries organised and engaged in rioting calling for an end to the war, and managed to close down factories and stop public transportation. The Italian army was forced to enter Milan with tanks and machine guns to face Bolsheviks and anarchists, who fought violently until May 23 when the army gained control of the city. Almost 50 people (including three Italian soldiers) were killed and over 800 people were arrested.
