January 30, 1969. On a rooftop in London, Paul McCartney, John Lennon, George Harrison and Ringo Starr performed together live for the last time ever.
At that time, many fans did not know that the 'Fab Four' were coming to an end.
Fifty years later, the band is still considered one of the most successful and important in the history of music.
But why were the Beatles so important? And how do they compare to a modern-day supergroup, like K-Pop superstars, BTS?
In 1957, a sixteen-year old boy named John Lennon created a group called the Quarrymen, and later his friend, Paul McCartney joined.
Over the next five years, John and Paul's band totally transformed into a new group called The Beatles. They were joined by Paul's friend, George Harrison, on guitar and session drummer Ringo Starr.
They released their first UK No. 1 single 'From Me To You' in 1963, and went on to have 16 more UK No. 1's.
In total, they spent 65 weeks at the top of the UK charts!
And for one week in April 1964, the Beatles achieved something that had never been done before - they took the top five best-selling singles in the United States Billboard chart!
But what was so special about this band?
Many people feel that The Beatles were a groundbreaking band.
At first they were mainly influenced by the rock and roll genre of the '50s, but over time they came up with new ways of making music.
Their original ideas went on to influence hundreds of bands that followed them.
And even 60 years on from their creation, they remain one of the world's most popular music groups of all time.
The Beatles changed their look over the years and set trends for the millions of fans around the world.
As their music evolved, so did their style. Take a look!
In the 1963, the British public had not seen anything quite like the crowds that The Beatles attracted.
The band's popularity with younger audiences, particularly women, became a big talking point in the UK.
Many older people were horrified at how Beatles' fans behaved - many of them screaming, cheering, dancing and at times they tried to storm onto stage!
This fan mania became known as 'Beatlemania', and it followed the group from the UK to the United States.
There performance on the famous Ed Sullivan show was viewed by 73 million people in 1964.
If you can imagine, that's the same as every person in the UK today tuning in to watch one television programme!
Even though the band split up nearly 50 years ago, there are still millions of Beatles fans around the world today.
We wonder how you guys will remember bands like BTS and One Direction 50 years from now!
