Vladimir Lenin arrived in Russia after a decade of self-imposed exile.

Lenin, the leader of the Bolshevik Party, had left Russia in 1907 after Tsar Nicholas II cancelled many of the reforms he had promised following the 1905 revolution. While abroad he remained busy organising Bolshevik groups and publishing Marxist works, but following the February Revolution and the abdication of the Tsar in 1917 he began making plans to return to Russia.

The country had been weakened by the exhausting toll of the First World War and this, combined with disastrous food shortages, had prompted the popular revolt that overthrew the Tsar. In his place the Provisional Government ruled the country, and they opted to continue the war effort despite strong opposition from the Russian people.

German officials were keen to further destabilise the situation. Despite being at war, Lenin and other Bolshevik exiles were granted permission to return to Russia from Switzerland through Germany in a ‘sealed train’. This meant that Lenin and his companions were never legally recognised as being in Germany.

The group then took a ferry to Sweden followed by a second train to Finland, arriving at Finland Station in Petrograd on 16 April. The next day Lenin published the April Theses in which he denounced both the Provisional Government and the First World War, and claimed that Russia was “passing from the first stage of the revolution…to its second stage, which must place power in the hands of the proletariat and the poorest sections of the peasants.”

Less than seven months later the Bolsheviks overthrew the Provisional Government in the October Revolution.

On the 11th February 1979 Mohammad Reza Shah Pahlavi, the last Shah of Iran, was overthrown as a result of the Iranian Revolution. His overthrow saw the end of the 2,500 year old monarchy in Iran and ushered in a theocracy overseen by the Ayatollah Khomeini.

Under the Shah, Iran enjoyed immense wealth built on an abundant supply of oil, although the vast majority of the population continued to live in poverty. The Shah, who had come to power in 1941, tried to secure support by using oil money to modernize Iran. However these reforms, known as the ‘White Revolution’ were interpreted by some as pandering to Western ideals that went against Iran’s traditions.

Despite the establishment of the brutal SAVAK secret police, a growing number of Iranians were increasingly turning against the Shah. They found a leader in the Muslim scholar Ayatollah Khomeini who, despite being forced into exile in 1964, continued to be a vocal critic of the Shah’s government. He played down his intention to establish an Islamic government, focusing instead on his desire to overthrow the Shah.

On September 8th 1978, over 500 people were killed by soldiers on what became known as ‘Black Friday’. The Shah’s attempts to restore calm had no effect on the public, who continued to call for his removal.

Recognising that his overthrow was becoming inevitable, the Shah and his wife left Iran on January 15 for the USA. Khomeini returned to Iran two weeks later. Finally, on the 11th February the Supreme Military Council ordered all troops back to their barracks, effectively handing control to Khomeini and his supporters.

On the 22nd January 1905, the Bloody Sunday massacre took place in the Russian capital Saint Petersburg. Soldiers of the Imperial Guard fired on protesters led by the Orthodox Priest Father Georgy Gapon as they marched towards the Winter Palace where they planned to present a petition to Tsar Nicholas II.

By 1905 there was growing discontent amongst the urban working class. Father Gapon had established the “Assembly of the Russian Factory and Mill Workers of the City of St. Petersburg” to promote workers’ rights in 1903, but after four Assembly members from the Putilov ironworks were sacked from their jobs in December 1904, workers across the city went on strike. Capitalising on the situation Father Gapon drafted a petition to the Tsar calling for improved working conditions and various other reforms that received 150,000 signatures.

On the morning of the 22nd January workers marched with the petition to the Winter Palace, alongside religious icons and pictures of the Tsar. Gapon had already notified the authorities of the petition and the march, and in response approximately 10,000 troops from the Imperial Guard were placed around the palace. However, why they began firing on the peaceful march is unclear. Even the number killed or injured is uncertain with estimates ranging from the government’s official figure of 96 dead to revolutionary claims of more than 4,000.

The Tsar was not in the palace at the time, and did not give an order for the troops to fire, but was widely blamed for the massacre. In response strikes and protests spread around the country, and eventually developed into the 1905 Revolution.

On the 7th November 1917, Red Guards entered the Winter Palace in St Petersburg in a defining event of the Bolshevik Revolution. Sometimes referred to as the October Revolution, the 7th November is the date from the modern Gregorian calendar that aligns with the 25th October on the old style Julian calendar, from which the revolution got its alternative name.

On the night of the 6th November Leon Trotsky led the Red Guards to take control of key government buildings and communication points such as post offices, bridges and the State Bank. Although the Red Guards were armed, historians generally accept that the takeover was carried out without bloodshed or indeed any shots being fired.

Throughout the 7th November large crowds of troops sympathetic to the Bolsheviks began to surround the Winter Palace. The actual attack on the palace began after a signal shot fired from cruiser ship Aurora. Soviet accounts of the night, portrayed most powerfully in Sergei Eisenstein’s film reenactment, present the takeover of the Winter Palace as a huge battle. However, this popular image is a fabrication. The large number of Red Guards marching towards the palace led to the Cossacks guarding the palace to desert their posts, while the remaining Cadets and volunteers from the Women’s Battalion laid down their weapons and surrendered after the Red Guards found their way inside the palace through an open door.

The remnants of the Provisional Government were discovered in a small dining room and arrested. Meanwhile the wine cellar was looted, leading to what historian Orlando Figes suggested was perhaps, “the biggest hangover in history”.

Mussolini, who was determined to restore the glory of the Roman Empire following the ‘mutilated victory’ of the First World War, had formed the precursor to the Fascist Party in 1919. His skill as an orator, the intimidating power of his Blackshirts, and the relative weaknesses of the existing liberal government all contributed to the speed at which the Fascists gained influence.

On 24 October 1922 Mussolini went on stage at the Fascist Congress in Naples to declare his willingness to use the power of the Fascist movement to overthrow the government of liberal Prime Minister Luigi Facta. Four days later approximately 30,000 Blackshirts from around the country gathered in the capital in an event known as the March on Rome. As they filled the streets and occupied public buildings, they called for Facta’s resignation.

The Prime Minister chose to oppose the attempted revolution, but King Victor Emmanuel III refused his request to declare martial law. Stunned by the King’s rejection of military action, Facta offered his resignation which was immediately accepted. Victor Emmanuel later invited Mussolini to form a government, whose cabinet was sworn in on 31 October in front of the King himself.

The establishment of Mussolini’s government was greeted by a victory march by tens of thousands of Blackshirts. In time the March on Rome would achieve mythical status among Fascists as a revolutionary seizure of power, but the reality is that Mussolini was granted power the King. Within a few years, however, he would transform the country into a dictatorship.

On the 6th October 1981 Egyptian President Anwar Sadat was assassinated by members of the Egyptian Islamic Jihad, a terrorist group that was enraged by the peace treaty he had negotiated with Israel. His assassins were arrested, put on trial and executed, while the death of the President led to Vice President Hosni Mubarak becoming the premier just eight days after the assassination. He went on to rule for almost 30 years before he stepped down during the 2011 Egyptian Revolution.

Three years before his assassination, Sadat had signed the Camp David Accords and jointly received the Nobel Peace Prize with Israeli Prime Minister Menachem Begin. The Accords led to Egypt signing the Egypt–Israel Peace Treaty in 1979, which marked the first time that an Arab nation had formally recognised Israel. Although the treaty ended 40 years of almost continuous war between the two nations, it was met with hostility by some people in Egypt who felt that Sadat had betrayed the Palestinian cause and the honour or Egypt.

With hostility to his rule growing at home, Sadat was surrounded by security as he observed the 6th October parade that marked the Egyptian crossing of the Suez Canal at the start of the Yom Kippur War. The assassins were in the procession on board an artillery truck that stopped directly in front of Sadat and allowed them to approach the President. Believing that this was part of the proceedings, Sadat stood to salute them but was killed in a hail of grenades and indiscriminate firing of AK-47s. He died in hospital two hours later.

The Reign of Terror began in France when Bertrand Barère, a member of the Committee of Public Safety, made a speech in favour of it that ended with the exclamation, “Let’s make terror the order of the day!”

Although there is debate amongst historians regarding the exact date that the Reign of Terror began, Barère made his speech at a time that Paris Commune was agitating for a more proactive approach against enemies of the revolution. Less than two weeks later the National Convention passed the Law of Suspects. This led to the arrest of both declared and suspected opponents of the government. This was one of the key causes of the more than 16,000 executions that took place during the Terror.

The following February Robespierre himself justified the government’s policy as ‘nothing more than speedy, severe and inflexible justice’. While some historians disagree with Robespierre’s argument that the Terror was necessary to combat counter-revolutionary elements in French society, there can be little doubt that France’s fortunes improved during its time.

However, the Terror had also begun to face opposition. By the end of 1793 two factions – one calling for an escalation, the other for moderation – had emerged. Although the leaders of both groups were executed, Robespierre’s dominance of the Committee of Public Safety was now seen as a threat to the National Convention itself.

In the session on 27 July 1794, members of the Convention turned against Robespierre and his allies. Shouts of “Down with the tyrant! Arrest him!” were heard in the chamber. Robespierre and 21 followers were arrested, and later executed, in what became known as the Thermidorian Reaction.

At around 11pm on the 20th August 1968, troops from the USSR, Bulgaria, Poland and Hungary entered Czechoslovakia in an invasion that brought the Prague Spring to an end. The invasion, known as Operation Danube, led to almost half a million soldiers crossing the border to bring Alexander Dubček’s reforms to an end.

The Prague Spring began in early January, shortly after Dubček became the leader of Czechoslovakia. Keen to push forward with de-Stalinisation within the country, he granted greater freedom to the press and introduced a programme of ‘socialism with a human face’ by which he intended to decentralise parts the economy and introduce some limited democratic reforms.

This new openness saw open criticisms of the Czechoslovakian government begin to appear in the press, which concerned the other Warsaw Pact countries. János Kádár, the leader of Hungary who came to power after the fall of Imre Nagy in 1956, even warned that the situation in Czechoslovakia seemed “similar to the prologue of the Hungarian counterrevolution”.

Concerned that Dubček’s reforms might spread to other Eastern Bloc countries and threaten the USSR’s security, the Soviet leader Brezhnev chose to open negotiations with the Czechoslovakian leadership that lasted into August. The talks ended in compromise, but Brezhnev continued to be unhappy with the situation and began to prepare military intervention.

Overwhelmed by the military invasion, Dubček asked his people not to resist. 72 Czech and Slovak soldiers and 108 civilians were killed, with a further 500 civilians injured. It later emerged that members of the Czechoslovakian government had asked for Soviet assistance against Dubček’s reforms.

On the 19th August 1991 Mikhail Gorbachev, the President of the Soviet Union, was placed under house arrest in what is known as the August Coup. Opposed to Gorbachev’s reforms, the leaders of the coup believed that the new Union of Sovereign States, which had been approved in a union-wide referendum, threatened the complete disintegration of the USSR. A number of individual states had already declared their independence, but the New Union Treaty would devolve much of the Soviet Union’s remaining power to individual states.

It was while Gorbachev was on holiday in Foros, a resort in the Crimea, that the coup was launched. On the 17th August, the coup’s leaders met with Gorbachev and demanded that he either declare a state of emergency or resign. Although the specific details of the conversation are unclear, the outcome was that Gorbachev refused.

Gorbachev was placed under house arrest, and the leaders of the coup – known as the Gang of Eight – created the State Committee of the State of Emergency to govern the USSR due to Gorbachev suffering from an “illness”. The changes in government were announced on state media on the morning of the 19th but, having chosen not to arrest Russian President Boris Yeltsin, the coup faced a blow when he began speaking against it. Two days later, the military supporting the coup failed to take control of the Russian parliament building in the face of civil resistance.

The coup collapsed on the 21st August, but the USSR was left seriously weakened. Just over four months later the Soviet Union was officially dissolved.

On the 10th August 1792, French revolutionary troops stormed the Tuileries Palace in Paris. Referred to by some historians as ‘the Second Revolution’ the events of the 10th August suspended the monarchy under King Louis XVI.

The royal family had lived in the Tuileries since the October Days of 1789 saw them brought back to Paris from Versailles. Louis and his family were virtually imprisoned, as proved when crowds barred them from moving to their summer residence in April 1791. This may have influenced Louis to carry out the failed Flight to Varennes two months later, after which the family were more officially held under house arrest in the Tuileries Palace.

The relationship between the royal family and the people of Paris continued to decline throughout 1792. The king did himself no favours by vetoing a range of decrees passed by the Legislative Assembly, but the situation grew worse with the threat of invasion from foreign armies. By the time of the Brunswick Manifesto on 1st August that lent foreign support to the royal family, the crowds of Paris held Louis and the concept of monarchy in absolute contempt.

On the morning of the 10th August, crowds massed outside the Tuileries. With Louis opting to take shelter in the Legislative Assembly building, his Swiss Guard who were left to defend the palace were eventually overrun after they ran out of ammunition. Approximately 800 people on the king’s side were killed, and Paris was put in the hands of the revolutionaries while the royal family were sent to the Temple prison.
