It's almost three weeks since George Floyd's death.
There have been protests around the world over the way police treat black people and highlighting racism and inequality in societies.
His family say they don't want his death to be in vain.
Radio 1 Newsbeat has been looking at 10 things that have already changed since George Floyd died.
1. Global tributes and protests
People are protesting with one message - Black Lives Matter.
They have marched in the past when other black people have been killed by police, but this time it's different.
There have been demonstrations in all 50 US states, including in places like Anna, a small village in Illinois - described locally as one of "the most racist places".
Cities in 50 countries have also held demonstrations.
There's a portrait of George Floyd on the side of a bombed-out building in Syria's Idlib province.
2. Statues being taken down
In the UK and the US statues and monuments of people with links to slavery are being toppled by demonstrators.
In the US statues of Christopher Columbus have been defaced or taken down.
Some argue removing statues is erasing history - others say they belong in museums rather than seeming to celebrate individuals.
3. Companies standing in solidarity with BLM
Lots of the world's biggest brands have been quick to pledge their support for the Black Lives Matter movement.
But some companies like L'Oreal Paris have faced criticism.
When it posted support, the transgender model Munroe Bergdorf responded, saying the brand "threw me to the wolves".
She was sacked by L'Oreal in 2017 for posting about "the racial violence of white people".
I have spoken with @loreal, please swipe for full statement.— Black Lives Matter ✊🏾 (@MunroeBergdorf) June 9, 2020
Thank you everyone for having my back with this matter over the past three years, it hasn't been easy.
Looking forward to new beginnings and a new positive relationship with the L'Oreal team.

At the time the company said her comments "are at odds" with their values but the new boss Delphine Viguier has apologised for the way the situation was handled.
4. Police officers charged
Derek Chauvin has been charged with murder and manslaughter over George Floyd's death - three other former officers face charges of aiding and abetting murder.
Other high-profile cases where black men died in police custody haven't led to officers being convicted.
According to the Attorney General in Minnesota - Keith Ellison, "it's not going to be easy to get a conviction", in the George Floyd case.
Only one officer in Minnesota has been convicted of killing a civilian while serving in the role.
5. Police departments are making changes
Minneapolis city council forced the police department to ban chokeholds and neck restraints.
Unannounced police raids, known as "no-knock warrants" have been scrapped in Louisville - where Breonna Taylor died.
She was at home in bed when police officers entered her apartment. She died after being shot eight times.
Defunding the police is another change protestors want - they argue too much cash is given to the police and it should be reduced.
New York City Mayor Bill de Blasio said he would divert money from the city's police department to social services.
6. Donating to charities and bailing out protestors
The George Floyd's memorial fund smashed its $1.5m (£1.19m) goal and became the most donated GoFundMe page on the website.
Millions of donations were also made to other causes related to racism.
Take the Minnesota Freedom Fund, for example. a small project created to help low income people cover the cost of bail - which can cost thousands.
Jameela Jamil, Harry Styles and Chrissey Teigan were amongst the celebrities donating to bail out protestors.
I’m donating to help post bail for arrested organizers.— Harry Styles. (@Harry_Styles) May 30, 2020
Look inwards, educate yourself and others.
LISTEN, READ, SHARE, DONATE and VOTE.
ENOUGH IS ENOUGH.
BLACK LIVES MATTER.
7. "You're a racist"
More people are speaking out about the everyday racism and discrimination they have faced.
Radio 1's Clara Amfo was praised for speaking openly about the impact George Floyd's death had on her and her mental health.
She said what happened had reinforced a feeling among black people "that people want our culture, but they do not want us".
"In other words, you want my talent, but you don't want me," Clara added.
Leona Lewis posted on her Instagram talking about a past experience where the singer says she and her dad were racially targeted in a shop.
She says she was told she was told she was "not allowed" to touch stuff in the store.
When the woman in the shop tried to apologise, Leona confronted her. "I said, 'you're a racist'."
8. Black out Tuesday
On Tuesday 2 June a series of black tiles were posted across social media as part of a protest called Blackout Tuesday.
Its intention was to 'black out' usual activity and take the time to learn about the Black Lives Matter movement.
It started off within the music industry with support from record labels and radio stations.
It was later criticised as the posts filled the BlackLivesMatter hashtag- hiding posts with important information and updates about the on-going protests.
9. Street names changed
Black Lives Matter Plaza is now the name of the street in Washington DC leading up the White House.
The mayor there changed the name because she wasn't happy with the way President Trump reacted to the protests.
The Mayor of New York says a street in each borough will be renamed "Black Lives Matter."
10. Programmes taken off streaming platforms
TV shows that contain "racially insensitive" or inappropriate characters are being removed from streaming services - although many argue we shouldn't judge comedy from previous eras by today's standards.
Little Britain and Come Fly with Me were pulled from iPlayer and Netflix because their use of Black face.
The Mighty Boosh and The League Of Gentlemen were also removed from Netflix.
Keith Lemon recently posted an apology for playing black characters in Bo 'Selecta and showed his support for Black Lives Matter.
