What was Sirius Black’s relationship with Voldemort?

Why was Sirius Black believed to be Voldemort’s right-hand man?

After the Potters were murdered, Sirius Black was arrested without trial on the testimony of Peter Pettigrew. The wizarding world assumed that Sirius, as the Potters’ Secret-Keeper, had betrayed them to Voldemort. He was branded a Death Eater and sent to Azkaban.

What actually happened?

Sirius was never a Death Eater. He had convinced James and Lily to switch Secret-Keepers to Peter Pettigrew at the last moment, hoping that would throw off Voldemort’s spies. It was Peter who betrayed them and then framed Sirius.

The irony

Sirius’s own clever plan to protect his friends is what made him the perfect scapegoat. The same loyalty that defined him became the rope that tied him to Azkaban for twelve years.

The implication: Sirius Black’s reputation as Voldemort’s lieutenant was entirely manufactured. The Ministry never questioned the false confession Peter planted.

What was Sirius Black known for?

His role as Harry’s godfather

Sirius was named godfather to Harry Potter shortly after the boy’s birth in 1980. After his escape, he risked everything to reach Harry, becoming the closest thing to a parent the boy had.

His time as an Animagus

Sirius, James Potter, and Peter Pettigrew became Animagi in 1974 so they could accompany Remus Lupin during his werewolf transformations. Sirius’s form was a large black dog, earning him the nickname Padfoot.

His involvement in the Order of the Phoenix

Sirius was a member of the original Order of the Phoenix during the First Wizarding War). After his escape, he rejoined the re-formed Order and fought until his death.

The pattern: Every major achievement in Sirius’s life—from the Marauders to the Order—was driven by loyalty to a small group of friends. That same loyalty cost him everything.

Why did Sirius Black turn bad?

The betrayal and framing by Peter Pettigrew

Sirius did not turn bad. He was framed by Peter Pettigrew, who murdered twelve Muggles and then faked his own death. Sirius was the one who suggested switching Secret-Keepers—a decision he regretted for the rest of his life.

His escape from Azkaban

Sirius escaped Azkaban in 1993 after learning that Peter Pettigrew was still alive. He transformed into his dog form and swam to the mainland, the only known unassisted escape from the fortress.

What to watch

The Ministry’s failure to conduct a fair trial meant that an innocent man rotted in Azkaban for over a decade. When he finally broke free, he became a fugitive who could never clear his name in his lifetime.

The catch: Sirius’s escape succeeded because the Dementors couldn’t sense his positive emotions—he was consumed by revenge.

Why did Sirius Black never marry?

His dedication to the war against Voldemort

Sirius never married, largely because his adult life was consumed by fighting Voldemort and later by protecting Harry. After graduating Hogwarts in 1978, he joined the Order and spent his years in active conflict.

His imprisonment

Twelve years in Azkaban removed any chance of building a family. By the time he escaped, he was focused entirely on Harry and the war. No known romantic relationships after Hogwarts are recorded in canon).

Why this matters: Sirius’s bachelorhood is not a mystery—it’s a direct consequence of a life stolen by a wrongful conviction. The freedom he fought for never included the chance to love freely.

Is Sirius Black related to Snape?

The Black family tree

Sirius and Severus Snape were not blood relatives. Sirius’s mother Walburga was a pure-blood Black, while Snape was a half-blood from a different lineage).

Sirius and Snape’s animosity

Their hatred stemmed from Hogwarts, where the Marauders’ feud with Snape turned into a lifelong enmity. Sirius nearly caused Snape’s death during a prank involving Remus Lupin’s transformation.

The trade-off: While Sirius and Snape shared no family ties, their personal war shaped much of Harry’s experience at Hogwarts. Both were complex men shaped by their choices—and their grudges.

Key quotes from the story

“If you want to know what a man’s like, take a good look at how he treats his inferiors, not his equals.”

— Sirius Black, Harry Potter and the Goblet of Fire

“He was a brave man. He died trying to save Harry’s life. That’s the truth.”

— Albus Dumbledore, speaking to Harry after Sirius’s death)

The legacy of Sirius Black

Sirius Black never got the life he deserved. He spent twelve years in a cell for a crime he didn’t commit, then two years as a fugitive, and died fighting the very wizard who had destroyed his family. But his sacrifice shaped Harry Potter into the man who finally ended Voldemort. For every young wizard reading the books today, the lesson is clear: loyalty and courage matter more than blood or reputation.
