When chatting to Ryan Seacrest on the red carpet, Wu described Crazy Rich Asians as a "historic" moment, as it saw a major studio telling a story centred on her experience as an Asian-American.
Hannah Beachler made history as she became the first black person to win the Oscar for production design, for her work on Black Panther with Jay Hart.
She thanked director Ryan Coogler for giving her "a safe space" and "brotherhood", and she had a message for the next generation.
Other than crazy red carpet moments and glamorous gowns, the Oscars is often a chance for actors to inspire fans with their speeches.
Some call for social and political change, like Spike Lee who exhorted the audience to "mobilise" ahead of the 2020 US presidential elections.
Others, like Olivia Colman, take the time to thank their nearest and dearest.
Here are some of the most inspiring moments of the night.
There's nothing more fun than seeing celebrities fawn over other celebrities - it helps us remember we're all the same.
And Richard E Grant is truly all of us when we see Barbra Streisand.
As Olivia Colman accepted her award for best actress, her speech was filled with many emotional and charming moments that made the world love her even more.
But the most-talked about moment was probably when she thanked and marvelled at Lady Gaga, while blowing her a kiss - because what else would you do when standing in front of greatness?
Lady Gaga and Bradley Cooper performed perhaps their steamiest rendition yet of Shallow, from their film A Star is Born.
The pair gazed adoringly at each other as they sang the song, with Gaga standing opposite Cooper before taking her place behind the grand piano.
As the song came to an end, Cooper sat beside Gaga and laid his head on hers as they belted out the final lyrics - which was probably around the same time Twitter imploded.
While introducing best picture nominee Black Panther, South African comedian Trevor Noah poked fun at people who think Wakanda, the fictional African nation in which it's set, is a real place.
"Growing up as a young boy in Wakanda, I would see T'Challa flying over our village, and he would remind me of a great Xhosa phrase," he said.
"'Abelungu abazi ubu ndiyaxoka', which means: 'In times like these, we are stronger when we fight together than when we try to fight apart."
And while it sounded beautiful and uplifting, that's not quite what the phrase actually means.
The BBC's Pumza Fihlani said the actual translation into English is: "White people don't know that I'm lying."
While most of the audience in Hollywood was none the wiser, Xhosa speakers on social media relished in the cheeky moment.
The Academy Awards going hostless for the first time since 1989 may have been a controversial move, but it seemed no-one really minded.
That's probably because everyone was far too busy tweeting about Lady Gaga and Bradley Cooper's sizzling chemistry or laughing about Trevor Noah trolling the audience.
Here are some of the Oscar moments that ruled social media.
The Duke and Duchess of Sussex are on a three-day visit to Morocco aiming to support girls' education and strengthening links with the UK.
