Rupert Murdoch is a bit of a controversial figure.

Former Australian Prime Minister Kevin Rudd once launched a petition calling for a royal commission into NewsCorp's dominance of Australian Media.

Rudd argued Rupert Murdoch's Australian media empire has been used to "attack opponents in business and politics by blending editorial opinion with news reporting," intimidating those with contrary views into silence. "These facts chill free speech and undermine public debate," the petition stated.

In a social media video announcing the petition, Rudd said "Murdoch has become a cancer, an arrogant cancer, on our democracy". Around the same time, the Murdoch family story was told in the documentaryThe Rise Of The Murdoch Dynasty.

It told the story of Rupert Murdoch's influence on world events like Brexit and Trump's election. And who could forget the fact that James Murdoch – Rupert's son – left the company after publicly criticising its views on issues like climate change.

What it all reflects is the murky area that Rupert Murdoch has wadded in for quite some time.

But who are the Murdochs? Who is Rupert married to? What's the story behind the best-known, most powerful media dynasty in the world?

Watch: The Rise Of The Murdoch Dynasty. Post continues below.

Rupert Murdoch's family life.

Rupert Murdoch's name is synonymous with media around the world. His company NewsCorp owns major Australian media includingThe Australian,The Daily Telegraph, Foxtel and Sky News, plus UK papersThe SunandThe Times, and US publications including theNew York PostandTheWall Street Journal.

And then there's his other company, Fox Corporation, responsible for the Fox Broadcasting Company,Fox Sportsand yes,Fox News.

Basically, Murdoch media is hard to avoid.

Rupert Murdoch himself is now 91, and still serving as executive chairman of News Corp and chairman of Fox Corporation. According to Forbes, his 2020 net worth is more than AU$20 billion, making him the 68th richest person in the world.

At age 21, he inherited a small regional newspaper following his father's death in 1952.

In 1956, Murdoch married Patricia Booker, a former shop assistant and flight attendant from Melbourne. They had one daughter, Prudence, in 1958, and divorced in 1967.

That same year he married Anna Maria Torv, a Scottish-born cadet journalist working atThe Daily Telegraphin Sydney. They had three children: Elisabeth Murdoch in 1968, Lachlan Murdoch in 1971 and James Murdoch in 1972.

They divorced in June 1999, and Murdoch married his third wife Wendi Deng just 17 days later. At the time, he was 68, while Wendi was 30.

They had two daughters, Grace, born in 2001 and Chloe, born in 2003.

In the later years of their marriage, rumours of Deng's closeness with former UK Prime Minister Tony Blair – who is also the godfather to Grace, now 21 – effectively led to their divorce.

Murdoch was said to feel betrayed by this, especially as the former PM had been a close friend and powerful political ally of his.

In 2013, a spokesperson for Blair flatly denied the rumours in a statement to The Hollywood Reporter,but it did little to quell the story.

In 2014, after Murdoch and Deng announced their divorce,Vanity Fairpublished a note written by Deng about a man named Tony: "He is so so charming and his clothes are so good. He has such [a] good body and he has really really good legs," it read.

It was no secret that Murdoch's sons – Lachlan in particular – did not get along with Deng. Lachlan only returned to the family business after his father's divorce.

Rupert Murdoch's relationship with Jerry Hall.

In January 2016, he announced his engagement to former American supermodel Jerry Hall (who was previously not-legally-married to Mick Jagger, and is the mother to four of Jagger's children).

Murdoch and Hall married in March of that year. At the time of his marriage, the billionaire announced on Twitter that he was "the luckiest AND happiest man in world", and would stop posting on the platform.

Before the wedding, a friend of the couple told The Guardian: "They are very sweet together, in a little couple bubble. They act like a married couple already, talking over each other, holding hands. She puts her feet up on his legs, they disagree on things like any married couple. She hates Trump, he understands Trump, it's been like that from the beginning."

In 2019, the couple spent AU$13.8 million on a house in London.

Last year, they celebrated Murdoch's 90th birthday together in New York. Interestingly, one of the guests not in attendance – as reported by Variety – was James Murdoch, the son who has been "publicly critical of aspects of his father's empire".

This week, it's been revealed that Murdoch, 91, and Hall, 65, are divorcing.

The divorce will be the fourth for Murdoch. The news has been reported by multiple reputable outlets, and was first reported by the New York Times. A spokesperson for Murdoch declined to comment when the report was brought to their attention. The couple have reportedly not been seen in public together in London since August 2021.

Rupert Murdoch's biggest controversy.

Murdoch's influence is undeniable. Forbes lists him as the 39th most powerful person in the world.

Though routinely criticised for tabloid media and bias, the biggest scandal surrounding his media career came in 2011, involving his now-defunct tabloidNews of the Worldand other British newspapers.

News of the Worldemployees were accused of phone hacking celebrities, politicians, members of the British royal family, deceased British soldiers, victims of the July 2005 London bombings and Milly Dowler, a 13-year-old schoolgirl who was murdered in 2002.

At the Leveson Inquiry into the culture, practices and ethics of the British press, he admitted a cover-up had taken place within theNews of the Worldto hide the scope of the phone hacking.

The scandal led to multiple arrests, including of formerNews of the Worldeditors Andy Coulson (who was at the time working as communications director for then-British Prime Minister David Cameron) and Rebekah Brooks.

In November 2015, former Australian prime minister Tony Abbott said that Murdoch "arguably has had more impact on the wider world than any other living Australian". Now, Rudd is advocating for a Royal Commission into just how large that impact has become.

As for Murdoch's family and kids, here's what we know.

Prudence Murdoch.

Prudence Murdoch is the eldest of Rupert Murdoch's six children, born in Adelaide to his first wife, Patricia Booker.

After her parents' divorce, Prudence fell out with her mother who remarried a Swiss man. Prudence chose to live with her dad and his new wife, Anna Maria Torv in London, after he purchasedNews of the World.

After her schooling, she worked briefly as a researcher atNews of the World.

In 1985, she married Crispin Odey, an English financier who would become the highest-earning hedge fund manager in London, but they separated the following year.

In 1989, Prudence married Alasdair MacLeod, an Eton-educated businessman who would shortly begin working for his new father-in-law. Prudence was strongly against MacLeod working in her family business, but Murdoch offered MacLeod a job behind her back.

Together they have three children, James, Angus and Clementine, and live in Sydney's eastern suburbs.

Elisabeth Murdoch.

Elisabeth Murdoch, 53, has become a successful businessmen and media entrepreneur.

In the '80s, she and her then-partner Elkin Kwesi Pianim purchased a pair of Californian television stations, KSBW and KSBY, on a US$35 million loan secured by her father. The couple reorganised and sold the stations within 18 months, making US$12 million profit.

In 2001, she founded the distribution company Shine in the UK - which was behind shows such asMasterChef,BroadchurchandOne Born Every Minute.The company was acquired by News Corporation in 2011, pocketing Elisabeth £153m (AU$277m) in a deal that was surrounded by accusations of nepotism.

Elisabeth and Pianim have two children, Cornelia, born in 1994 and Anna, born in 1997, and the couple split in 1998.

Elisabeth's second marriage was to public relations executive Matthew Freud, the son of former UK MP Sir Clement Freud and great-grandson of Sigmund Freud.

Freud allegedly did not get along with his father-in-law, accusing Rupert Murdoch of having an old-fashioned attitude to women in aVanity Fairinterview.

They had a 'feud' for much of the time Freud and Elisabeth were married. In 2013, The Guardian reported Freud had banned Murdoch from his 50th birthday party - because Murdoch's friend-turned-foe Tony Blair was attending.

Freud had also openly shared his disgust withFox Newsand had long-supported tighter restrictions on British newspapers which would've had an impact on his father-in-law's tabloids.

Freud and Elisabeth welcomed two children, Charlotte in 2000 and Samson in 2007, before divorcing in 2014.

In 2017, Elisabeth married artist Keith Tyson.

Last year, she co-founded Sister, a production company which developedChernobyl.

Lachlan Murdoch.

Murdoch's oldest son Lachlan, 50, is the executive chairman of Nova Entertainment, co-chairman of News Corp, and CEO of the Fox Corporation.

He studied philosophy at Princeton University before moving to Australia to work in the family business.

Lachlan was considered the most likely contender to run his father's entire empire until he resigned from his News Corp executive post in 2005.

But in March 2014, he returned to the family business as non-executive co-chairman of News Corp and 21st Century Fox Inc, seen as once again planning for succession.

This means he is in charge of the company that ownsFox News,which has become only more partisan and extreme in recent years. Asked recently if he agreed with the political views of the TV station, Lachlan replied: "I'm not embarrassed by what they do at all."
