It was taken on what would be the final day of protests by students in the ceremonial space in Beijing. 'Tianemen' is the name of the Gate of Heavenly Peace, a monument in China, of which the square is named after. It was also the stage for the 1919 'May Fourth Movement' and where Mao had declared a 'People's Republic' in 1949.
Students had occupied the square for 7 weeks to protest for greater democracy in the one party state. Protests were also taking place at that time Shanghai.

Late evening on 3 June Chinese government tanks entered the square along with 10,000 soldiers on the streets.
In the morning hundreds were massacred.
In China it is referred to as the 'June Fourth Incident' by those seeking to downplay the horrific events which took place. The country's censors suppress all mentions of the massacre, going as far as blocking combinations of the numbers 4, 6, and 1989.
The image persists, despite the day's bloodshed and defeat for the protestors.
Here are 5 other images which similarly capture moments of defiance from dates that should remain relevant for years to come.

Fernandes and others were accused of planning to use dynamite to blow up railways in the 'Baroda dynamite' case.
The defiant image of Fernandes, holding up his chains to photographers came to symbolise the crisis for the Indira Ghandi's Congress Party in government.
He was released, but not before being elected to the lower house of parliament from his jail cell.
Fernandes went on to be a Railway Minister and a Defence Minister in India's federal government.
Bree Newsome climbed the flag pole in Columbia, South Carolina and removed the Confederate Flag. Despite the defeat of the confederacy in 1865, and South Carolina's return to the Union, the flag had continued to fly.
Newsome was arrested, and days after released an essay explaining her actions.
For far too long, white supremacy has dominated the politics of America resulting in the creation of racist laws and cultural practices designed to subjugate non-whites. And the emblem of the confederacy, the stars and bars, in all its manifestations, has long been the most recognizable banner of this political ideology. It’s the banner of racial intimidation and fear whose popularity experiences an uptick whenever black Americans appear to be making gains economically and politically in this country.
The flag was taken down permanently in July 2015, despite opposition from KKK protestors.
