He had an older half-brother, Yakov Dzhugashvili (born 1907), from his father's first marriage to Kato Svanidze, and a younger sister, Svetlana, born in 1926.
The family also took in Artyom Sergeyev, the son of Fyodor Sergeyev, a close friend of Joseph.
Fyodor died in an accident four months after the birth of Artyom, so the boy was raised in the Stalin household.
As his mother was interested in pursuing a professional career, a nanny, Alexandra Bychokova, was hired to look after Stalin and Svetlana.
1921
Vasily Iosifovich Stalin Dzhugashvili (ვასილი იოსების ძე სტალინი ჯუღაშვილი, Василий Иосифович Сталин Джугашвили; 21 March 1921 – 19 March 1962) was the youngest son of Joseph Stalin, born from his second wife, Nadezhda Alliluyeva.
Vasily was born on 21 March 1921, the son of Joseph Stalin and Nadezhda Alliluyeva.
1932
On 9 November 1932 Vasily's mother shot herself.
To conceal the suicide, the children were told that Alliluyeva had died of peritonitis, a complication from appendicitis.
It would be 10 years before they learned the truth of their mother's death.
Svetlana would later write that the death of their mother had a profound impact on her brother.
She noted that he started to drink alcohol at the age of 13, and in drunken episodes would curse and attack her.
He became increasingly violent, especially towards Svetlana, and would be quite disruptive at Zubalovo, a dacha outside Moscow, his primary residence.
After the death of Alliluyeva, Joseph Stalin ceased to visit his children; only the nursemaid and head of Stalin's security guards looked after Vasily and his sister.
With his father absent, Vasily became close to Károly Pauker, a Hungarian who worked as a bodyguard for his father.
1933
In 1933 Stalin and his sister were enrolled in Moscow Model School No. 25, a prominent public school.
Stalin was a poor student, and Svetlana would recall that the teachers would frequently discuss his poor behavior with his father.
1937
Pauker frequently travelled out of the Soviet Union and would bring back gifts to the younger Stalin, though during the Great Purge his foreign nationality and trips abroad had made him a target for repression, and he was shot in August 1937.
Stalin spent time with other guards as well, drinking with them.
He would later reflect that his entire life had been "spent among adults, among guards" and that it left a "deep mark on the whole of [his] private life and character".
He tried to gain the attention of his father, writing letters about what he was doing, but the elder Stalin did not reciprocate.
He was transferred in 1937 to the Special School No. 2, though the faculty there did nothing to curtail his behaviour.
One year later Stalin, now aged 18, was sent to the Kachinsk Military Aviation School.
He had initially wanted to attend an artillery school, but as his half-brother Yakov was already enrolled in one, their father did not want them both in the same military branch.
His father ordered the school not to grant him any favours or special privileges due to his name, and asked that he should stay in regular army barracks.
1939
Stalin did quite well at this school, with a 1939 report to his father noting he was "[d]edicated to the cause of the Party of Lenin-Stalin", and was "interested and well versed in questions related to international and domestic situation".
However, the report also noted Stalin tended to study poorly, was unshaven for duty, and reacted "badly to snafus in flight".
1940
He completed his schooling in March 1940, with his final marks stating he did "excellent" and was given the rank of air force lieutenant.
On 31 December 1940, at 20 years old, he married Galina Burdonskaya, a student at the Moscow State University of Printing Arts.
1941
He joined the Air Force when Nazi Germany launched Operation Barbarossa, the invasion of the Soviet Union, in 1941.
After the war, he held a few command posts.
The Soviet Union was invaded by Nazi Germany on 22 June 1941.
Stalin was transferred to the front in August 1941 and given the surname Ivanov in an attempt to conceal his identity.
As the son of Stalin, he rarely flew in combat, and when he did he was accompanied by a formation.
Vasily took part in 29 combat missions, and it is said to have shot down two enemy aircraft.
As the son of the Soviet leader, Vasily was hated by most of his colleagues, who felt he was an informant for his father.
1942
In the spring of 1942 he was sent back to Moscow, and given the role of inspecting the condition of the air force.
He mainly stayed in Moscow for the rest of the war.
1943
Bored by his new role, Vasily found himself in trouble after the 4th of April 1943 incident where he had explosives dropped into the Moskva River, injuring himself and killing a flight engineer.
1953
After his father died in 1953, Vasily lost his authority, developed a severe alcohol problem, and was ultimately arrested and sent to prison.
1962
He was later granted clemency, though he spent the remainder of his life between imprisonment and hospitalization until he died in 1962.
