Prince Harry speaks of the "leaking and... planting of stories" as part of a "dirty game" in a new trailer for his upcoming Netflix series.
He describes the "pain and suffering of women marrying into this institution" in an apparent reference to his wife, Meghan, and mother, Princess Diana.
The issue of race is also raised, with a commentator saying of the couple's experience: "It's about hatred. It's about race."
The series is released on Thursday.
A further three episodes will follow on 15 December.
The latest trailer shows a series of hard-hitting comments, which suggest no sign of any olive branches to the Royal Family.
Instead there is a commentary that says "there was a war against Meghan to suit other people's agendas".
Over an image of senior royals on the Buckingham Palace balcony, Prince Harry says: "There's a hierarchy of the family. You know there's leaking, but there's also planting of stories."
The trailer for the series, which begins with three episodes on Thursday, suggests a narrative that begins with Meghan being warmly received by the public - treated like a "royal rock star".
But then it suggests "everything changed", with Prince Harry and Meghan undermined, and with a commentator claiming it was driven in by part by "hatred" and "race".
The trailer links Meghan's experience to the pressure faced by Princess Diana, with images of the press attention surrounding her - with Prince Harry saying "I realised, they're never going to protect you".
"We know the full truth," says Prince Harry at the end.
Last week, a teaser for the season was released at the same time as Prince Harry's brother, the Prince of Wales, was in the US to present his Earthshot environmental prize.
The documentary is said to offer an insight into what the couple describe as the inside story of why they stepped back from their royal duties.
Prince Harry and Meghan formally stepped down as senior royals in March 2020.
A year later, during an interview with US talk show host Oprah Winfrey, Meghan said life within the Royal Family became so difficult at times she "didn't want to be alive anymore".
