The Wizarding World in the Harry Potter series isn't a different magical land, as witches and wizards coexist with Muggles but hide their existence. Within the series' history, this wasn't always the case, as the Statute of Secrecy, established in the 17th century, resulted in the separation of wizards and Muggles. Villains like Voldemort sought to end this facade in the name of wizarding supremacy but did so through brutal means that resulted in many casualties.
There have also been plenty of other cases where witches and wizards have severely harmed Muggles (sometimes vice versa), and this has exposed the Wizarding World. While the majority of such cases were covered up by the Ministry, the impact they had was extreme and continues to be felt.

During Harry's final departure from Privet Drive, he was escorted by his allies in the Order of the Phoenix. Six of his friends from the Order took on his appearance through Polyjuice Potion, making seven Harrys including the real one.
Harry rode the enchanted, flying motorbike, Bill and Fleur were on Thestrals, and the rest were on flying broomsticks.
Upon leaving the protective bubble, the party was ambushed by Death Eaters in the sky after the initial intention of the Order to hide in the clouds was dropped. Following this, the group split away and everyone exposed their use of magic by conjuring dark magic that they shot through the air, with Muggles on the ground witnessing the event.
Moreover, Voldemort arrived without the need for anything to carry himself, as he used his flying powers. All this took place in the middle of London as the group flew toward the Burrow, meaning the city had a full view of the battle.
Harry's Firebolt crashed to the ground, along with part of the motorbike, and Hedwig's cage exploded upon impact.
Non-magical people ended up learning about wizards this way, requiring the Ministry to track the witnesses down to erase their memories. The Wizarding World didn't learn about this, as the Daily Prophet didn't publish the event.
The biggest consequence of this battle was Voldemort's realization that he could openly do magic without worrying about the Ministry, as he then executed the Minister a few days after.Breaks the Statute?

On October 31, 1981, Voldemort was unsuccessful in slaying baby Harry, and his disappearance marked the end of the Great Wizarding War. In celebration, the British Wizarding World dropped all pretense of blending in with Muggles and made public appearances.
The next day, Vernon Dursley noticed a number of people in long, wizarding robes openly talking about Lord Voldemort's downfall, with one even embracing Vernon out of happiness. Across the country, particularly in Kent, wizards used magical fireworks across the sky, which Muggle news reported as shooting stars.
This got to the point where Muggles took their worries to the meteorological department, as no one could explain how those shooting stars were falling. Moreover, wizards sending owls to one another resulted in the birds gathering in great numbers and alarming Muggles.
All this broke the International Statute of Secrecy in many ways and was cause for the impeachment of Minister for Magic Millicent Bagnold. However, she acquitted herself by claiming, "I assert our inalienable right to party."Breaks the Statute?
The Death Eaters' Attack Of The Muggle Family At The Quidditch World CupPhoto: Harry Potter and the Goblet of Fire / Warner Bros. Pictures
The Quidditch World Cup campsite was a Muggle campground in Dartmoor that the Ministry of Magic rented from Mr. Roberts, who was the manager of the ground. Wizards were instructed to pretend to be Muggles so as not to give away their status as magical people, with Obliviators wiping Mr. Roberts's memory whenever he became suspicious.
However, the biggest crime against Muggles and display of magical superiority happened against Mr. Roberts and his family after the World Cup ended. Death Eaters reunited to don their robes and attack the Muggles, comprising Mr. Roberts, his wife, and their two children.
They were levitated off the ground, to the point where the children spun around as high as 60 feet into the sky. Mrs. Roberts was violated by being hung upside down, causing her nightdress to fall down. The entire family was attacked for some time until Ministry officials intervened, but the Roberts family came to know about wizards as a result.
Although the Muggles' memories were wiped, the fallout was enormous, as wizards from abroad began to fear Britain and the Ministry of Magic came under severe scrutiny for allowing the terrible treatment of four Muggles to take place for so long at a public event.Breaks the Statute?
Peter Pettigrew's Explosion Of A Public StreetPhoto: Harry Potter and the Deathly Hallows - Part 1 / Warner Bros. Pictures
After Voldemort's failure to kill Harry, the traitor Pettigrew decided to flee, since he knew Sirius Black would realize he gave up the location of the Potters. However, Sirius managed to track Pettigrew down in a busy London street, where Pettigrew realized he could fake his demise. He loudly accused Sirius of betraying James and Lily, which onlooking Muggles heard and witnessed.
Pettigrew then used a blasting curse that left a massive crater in the street to expose the sewer pipes below, killing 12 Muggles in the process. Pettigrew then fled during the commotion, which also resulted in 50 Muggles learning about wizards as they saw the magic take place, although they mistook Sirius to be the one to cast the spell since Pettigrew fired it behind his back.
Cornelius Fudge, Junior Minister in the Department of Magical Accidents and Catastrophes, had his team erase the memory of the Muggles and arrested Sirius, who was wrongfully convicted of Pettigrew's crime and sent to Azkaban for life, from where he escaped 12 years later.Breaks the Statute?
