After Petunia's sister Lily and brother-in-law, James Potter, were killed by Voldemort in their own home, Petunia remained the sole surviving blood relative of Harry's. Both Wizard and Muggle law demanded that Petunia and Vernon be the new legal guardians of Harry Potter, which they accepted (albeit reluctantly).
When he was just a baby, his parents were killed in their home while trying to protect Harry from the purest evil in the Wizarding World, the noseless Lord Voldemort. Because his parents suddenly died, he was sent to live with his next of kin, his mom's sister Petunia Dursley.
Petunia never showed any love and affection at all towards Harry because he reminded her of Lily and the wizarding world. She treated him as a waste of space, giving him the cupboard under the stairs at first and making him do all the chores. She, along with Vernon, ignored most of Harry's birthdays.

Why did Malfoy's mom save Harry?
Narcissa may have been many things; she was cruel and distant and happy to watch her family return to Lord Voldemort's side as he rose again, but she was also self-sacrificing; she loved her son and her husband and she thought nothing of putting herself in danger to protect them.
JK Rowling revealed in an interview (via Mugglenet) that both Harry's paternal and maternal Grandparents had died, leaving Aunt Petunia as Harry's only blood relative. Rowling explains, disposing of Harry's Grandparents was purely to provide a more interesting backstory for Harry.
Several years later, however, Hermione was forced to alter her parents' memories and give them new identities as Wendell and Monica Wilkins, to protect them from the Death Eaters. After the Second Wizarding War ended, Hermione found Mr Granger and his wife in Australia and returned their memories.
Many of the first memories that Harry had gazed upon depicted his future Aunt Petunia and unwittingly explained to him the reasons for her hatred of him and magic overall, such as: her falling out with his mother as children, Petunia's jealousy of Lily's magical abilities and her childhood enmity with Snape.
In Harry Potter and the Deathly Hallows, Harry observed a memory that revealed that Petunia's biggest secret was that she had once been desperate to go with her sister to Hogwarts. She felt rejected by the wizarding world and therefore resented it, and that only grew worse when Lily was killed.
Mrs. Dursley — wife of Dudley and mother of at least two children. Marjorie Dursley — sister of Vernon; a breeder of bulldogs. Petunia Dursley née Evans — wife of Vernon and mother of Dudley; a housewife.
Who took care of Harry Potter after his parents died?
Since Harry was so young when his parents died, he has no memory of them (or their deaths) and relies on information from other people in his life. Unfortunately for Harry, he was raised by his Aunt Petunia (Lily's sister) and Uncle Vernon Dursley….
The two children of Dudley Dursley and his wife were Muggles. They were occasionally visited by their magical second cousins, the two sons and daughter of their father's cousin Harry Potter. It is unknown whether they knew of their cousins' magical heritage.
Hermione also knew that her parents, and anyone else she associated with, would be in serious danger because of her friendship with Harry. And so, she chose to erase herself from her parents' minds. Hermione wanted to keep her parents safe from Voldemort by ensuring he had no reason to come knocking.
Ginny is introduced in the first book Harry Potter and the Philosopher's Stone, as the youngest sibling and only daughter of Arthur and Molly Weasley. She becomes Harry's main love interest and eventually marries him at the end of the series. She is portrayed by Bonnie Wright in all eight Harry Potter films.
One of Petunia Dursley's biggest secrets was the promise she made to Albus Dumbledore. When James and Lily were killed at the hand of Voldemort and Harry was dropped off on the doorstep of 4 Privet Drive, there was a letter accompanying him.
When Harry says Aunt Petunia never really loved him, Albus Dumbledore explains that by taking him in, she sealed the charm Dumbledore placed upon him. "You need return there only once a year, but as long as you can still call it home, there he cannot hurt you," explains Dumbledore.
Harry describes Umbridge to Sirius Black, saying that she's vile enough to be a Death Eater, despite not being one. Umbridge is also depicted to be a prejudiced person, despising half-breeds and Muggle-born witches and wizards to the point of firing Hagrid due to his half-giant birth status.
She and her husband were proud and accepting of their daughter's identity as a witch, which explained some strange things which happened around her when she was a child. They entered the magical world in 1992 to buy Hermione's school supplies, and were assisted by Arthur Weasley.
Rose Granger-Weasley was the daughter of Ron Weasley and Hermione Granger. She attended Hogwarts for the first time in the same year as Albus Potter and Scorpius Malfoy. Unlike the boys, Rose was sorted into Gryffindor, following in the footsteps of her parents.
As a single werewolf, it is understandable that Remus could not take care of Harry after his parents died. It's also possible he was not informed where Harry was placed and thus couldn't write to him in his early years at the Dursleys.
James Potter was killed trying to save his wife and child. Lily Potter then shielded her infant son when Voldemort unleashed the Killing Curse, causing it to bounce back and disintegrate his physical body. Harry survived but was left with a lightning-shaped scar on his forehead and a nickname: "The Boy Who Lived."
The children of Harry and Ginny Potter were considered half-bloods because although Ginny was pure-blood, Harry's mother was Muggle-born. The term was used as an insult from members of fanatical pure-blood families.
