We have today launched an appeal to those of you who played any part in the revolutionary events of 1968 to come forward and share your memories of that historic year.
"A storm swept the world in 1968," wrote Tariq Ali in the Guardian last month. "It started in Vietnam, then blew across Asia, crossing the sea and the mountains to Europe and beyond. A brutal war waged by the US against a poor south-east Asian country was seen every night on television. The cumulative impact of watching the bombs drop, villages on fire and a country being doused with napalm and Agent Orange triggered a wave of global revolts not seen on such a scale before or since."
Wherever you were around the world in '68 - Britain, Germany, Italy, Belgium, Argentina, Brazil, Colombia, Pakistan, Japan or elsewhere - we want to hear from you.
What was your level of involvement? Did you watch a protest take place or help run a movement? Were you part of that generation? What were your hopes and ideals? And what do you feel is the legacy of '68?
The worker strikes, student protests, riots, citizen occupations and anti-war demonstrations that threatened to topple governments and change the world order have all been well-documented, but what did it really feel like to be there?
In this interactive gallery, you can view seven images from landmark protests across the world, and magnify faces to see if you or anyone you knew is among the crowd. But don't worry if you aren't in these particular photographs, we still want to hear your memories.
And if you were too young to take part, or not even born, perhaps you can share the experiences of your parents, other relatives or friends who were out on the streets that year.
