Ron is a member of the pure blood Weasley family. Both of his parents, Arthur and Molly, come from pure blood lines. Draco Malfoy describes the Weasleys as having, “red hair, freckles and more children than they can afford.” He is the fifth Weasley son to attend Hogwarts. His elder brother, Percy, is a prefect and his older twin brothers, Fred and George, excel academically and are extremely popular because of their pranks. Ron and his family don’t really know much about the muggle world and are often fascinated by the things that Harry tells them about that aspect of his life.
Ron has six siblings: Bill, Charlie, Percy, Fred, George, and Ginny. Ron often feels overlooked and left out. During their first meeting in Harry Potter and the Sorcerer Stone, Ron tells Harry, “Every one expects me to do as well as the others, but if I do, it’s no big deal, because they did it first.”
Besides Hagrid, Ron is Harry’s first friend in the wizarding world and at Hogwarts. They meet on the platform 9 ¾ and then share a compartment on the train. They bond when Harry buys all of the tea lady’s sweets to share with Ron who only has homemade sandwiches to eat.
Ron helps Harry defeat Voldemort in Harry Potter and the Sorcerer Stone by directing their trio as they play a life size version of wizard’s chess.

In the second book of the series, Harry Potter and the Chamber of Secrets, Ron and his twin brothers, Fred and George, steal their father’s flying car and drive to the Dursley’s home to rescue Harry. Their father is curious about how this artefact operated, but their mother is livid.
In the fourth book of the series, Harry Potter and the Goblet of Fire, Ron and Harry fall out when Harry is selected as the fourth participant in the Triwizard Tournament.

They don’t reconcile until Ron sees how dangerous the tournament is and realizes that Harry would never sign up for it.
Ron realizes that he may have romantic feelings for Hermione when she is Viktor Krum’s date for the Yule Ball.
Ron’s first girlfriend is Lavender Brown. They start dating during their sixth year at Hogwarts. Part of his reason for doing it is obviously to make Hermione jealous. They spend a lot of time making out (snogging) in public. She gives also gives him the annoying nickname, Won Won.
Ron destroys one of Voldemort’s horcruxes, Slytherin’s Locket, but not before the necklace convinces him to abandon Harry and Hermione. The locket plays on Ron’s insecurities and whispers to him, “I have seen your dreams, Ronald Weasley, and I have seen your fears. All you desire is possible, but all that you dread is also possible. . .Least loved, always, by the mother who craved a daughter. . .Least loved, now, by the girl who prefers your friend. . .Second best, always, eternally overshadowed. . .” Eventually Ron destroys, but not after much temptation and anger.
