Buckingham Palace banned the hiring of "coloured immigrants or foreigners" until at least the late 1960s, newly discovered documents show.
The Guardian reports that unearthed documents from the U.K.'s National Archive reveal Queen Elizabeth's chief financial manager announced in 1968 that "it was not, in fact, the practice to appoint coloured immigrants or foreigners" to clerical roles within the palace.
Minorities, however, were placed in roles within the palace as domestic servants.
The documents also show that in 1970s, the palace went to bat against the government and negotiated to exempt Buckingham Palace from discriminatory hiring practice laws including those in regards to race and sex.
The palace "refused to answer questions about the ban and when it was revoked" when The Guardian reached out for comment.
This comes just months after Prince Harry's wife Meghan Markle went on record and claimed racism exists within the palace.
As Radar reported, the Duke and Duchess of Sussex told Oprah Winfrey that they experienced racism firsthand before their first child, Archie, was born.
In their explosive March interview, Markle explained there were "concerns and conversations about how dark [Archie's] skin might be when he's born."
Meghan -- who is mixed race -- refused to tell Oprah the identity of the person who stated such remarks.
In their interview, Markle also opened up about not feeling supported by the royal family.
She claims the mixture of pressure from the media and their lack of support almost drove her to suicide.
While Meghan -- who is currently pregnant with the couple's second child -- has been quiet on the royal family feud since her Oprah interview, Harry's brother Prince William's wife is allegedly trying to mend their relationships.
Kate Middleton's uncle recently revealed she is "trying to mediate" reconciliation between the feuding brothers.
“But if anyone can bring peace to the royals, Kate can,” her uncle told Closure Magazine. Calling Kate "a brilliant arbiter and peacemaker," he added, "every bone in her body is about making friends and doing the best she can."
