From public campaigns to viral memes, here are all the photos from 2021 we should be celebrating.
The amazing Free Britney campaign â€“ and its victory
After a long and arduous campaign, supporters of the famous pop star Britney Spears were delighted when her conservatorship was called off in November.

Bernie Sanders set the internet ablaze with his mittens
US Senator Bernie Sanders became an overnight sensation when he was pictured with his arms folded, mask and mittens on, and socially distanced from everyone around him, for Joe Bidenâ€™s inauguration back in January.

Covid vaccines were sent all around the world
A total of 58.2% of the worldâ€™s population has now received at least one vaccine, with 9.15 billion doses have been administered all over the world.

Celebrated codebreaker Alan Turing appeared on the Â£50 note
The new Â£50 banknote with the face of World War II codebreaker Alan Turing was revealed in June.
The late mathematician was treated terribly throughout his lifetime. He was prosecuted in 1952 for homosexual acts, and ended up accepting chemical castration treatment instead of going to prison.
However the new banknote was released to coincide with his birthday, a year after he was named the greatest person of the 20th Century by a 2019 BBC series.
Chloe Zhao became the first Asian woman to win the Best Director Oscar

Marcus Rashford was just one of several England footballers who faced abhorrent racist abuse after failing to score during the Euro 2020 finalâ€™s penalty shootout.
A mural of the footballer, who is also a campaigner against child poverty, was then defaced â€“ only for the graffiti to be concealed by loving messages from the local community as they fought back against Rashfordâ€™s abusers.
