The July Days refers to events in 1917 that took place in Petrograd, Russia, between 3 July and 7 July (Julian calendar) (16 July – 20 July, Gregorian calendar), when soldiers and industrial workers engaged in spontaneous demonstrations against the Russian Provisional Government. The Bolsheviks tried to provide leadership to the demonstrations. (Dates given in article Gregorian Calendar.)
The military attacked the peaceful demonstration and engaged in repression against the Bolsheviks. Lenin went into hiding, while other leaders were arrested. The outcome of the July Days represented a temporary decline in the growth of Bolshevik power and influence in the period before the October Revolution.
On 15 July 1917 the Kadets walked out of the Russian Provisional Government, threatening the Mensheviks and the Socialist Revolutionaries (SRs) with the breakup of the government coalition. A government crisis was the result.
Anti-war feelings were rife among the populace at that time, due to the recently failed Galician offensive which had caused an estimated 200,000 Russian casualties. These feelings intensified with the news of the failed offensive. Discontented workers started protests which soon spiraled into violent riots.
On 16 July spontaneous demonstrations broke out in Petrograd. They were started by the soldiers of the 1st Machine-gun Regiment, who were influenced by the anarchists. At a secret conference on 15 July the anarchists had decided to call the Petrograd workers and soldiers out to an anti-government demonstration.
The machine gunners’ appeal met with a favorable response from the soldiers of the Moscow, Pavlovsky, Grenadiers, and 1st Reserve regiments. These units marched out in a demonstration under the slogans “All Power to the Soviets”. Workers from factories joined them. The leadership of the All-Russian Central Executive Committee, dominated by Mensheviks and SRs, forbade the demonstration.
The Bolsheviks decided to provide leadership to the movement in order to give it an organized and peaceful character. On the afternoon of 17 July a peaceful demonstration of 500,000 workers, soldiers, and sailors under the slogan “All Power to the Soviets” was held. Anti-government demonstrations were also held in Moscow, Nizhny Novgorod, Krasnoyarsk, and other cities.
The military authorities sent troops against the demonstration, leaving more than 700 people killed and wounded. The SRs and Mensheviks supported punitive measures against the insurgents. They began to disarm workers, disband revolutionary military units, and carry out arrests. On 18–19 July the offices and printing plant of Pravda and the headquarters of the Bolshevik Central Committee were destroyed. On 19 July the Provisional Government issued an order for the arrest of Lenin, who was forced to go underground. On 20 July troops loyal to the regime arrived in Petrograd from the front.
Bolshevik involvement 
The demands which the workers and soldiers took to the streets with in the July Days were influenced by the Bolshevik Party. 'All Power to the Soviets' and other slogans put forth by the Bolsheviks were taken up by the workers and soldiers on the streets. The demonstration was organized by the Bolshevik Military Organization without authorization from the Central Committee after pressure from rank and file soldiers. During the afternoon of 16 July the Central Committee with the support of Kamenev, Trotsky and Zinoviev decided to take action to restrain the developing situation.
Under the pressure of what seemed like a developing mass demonstration of workers and soldiers in the streets, the leadership of the Bolshevik Military Organization, the Petersburg Committee and later on the Central Committee, reversed their decision, coming out in support of the street demonstrations. Both Trotsky and Zinoviev persistently argued that the street protests remain peaceful. After this decision, the Bolshevik Military Organization actively organized and supported the demonstration, mobilizing reinforcements from the front lines and dispatching armored cars to capture key posts including bridges and the Peter and Paul Fortress.
No public record was ever made of the internal debates of the Bolshevik Party around the July Days. There were some within the Bolshevik Party who advocated an intensification of activity on 17 July. Most prominent among those were Nikolai Podvoisky and Vladimir Nevsky, leaders of the Bolshevik Military Organization, V. Volodarsky, a member of the Petersburg Committee and Martin Latis of the Vyborg District Bolshevik Organization, who was highly critical of the Central Committee's decision to hold back the masses. Others in the Bolshevik Party, including V.I. Lenin were split on what to do. On 18 July at two or three o'clock in the morning, after the Provisional Government dispatched a number of loyal troops from the front to the streets of Petrograd and won the support of a number of previously neutral garrisons of troops, the Central Committee of the Bolshevik Party decided to call off the street demonstrations.
Kerensky ordered the arrest of Lenin and the other leading Bolsheviks, accusing them of inciting revolt with German financial backing. Lenin successfully went into hiding, staying first in the apartment of Benyamin Kayurov, before fleeing to Finland, but many other Bolshevik leaders were arrested, including Trotsky, Kamenev and Lunacharskii who were apprehended on 4 August. They remained in prison until Karensky released them in response to the Kornilov Affair.
The government crisis was intensified by the resignation of Prime Minister Lvov. On 21 July Kerensky became prime minister. The SR-Menshevik leadership of thee Soviets proclaimed the Provisional Government acknowledged it to have “unlimited powers.” The soviets became a powerless appendage of the government. The suppression of the demonstrations marked the end of dual power. The peaceful development of the revolution was seen as impossible.
