Their Majesties were crowned during a lavish ceremony on Saturday, bringing the entire nation together to mark the historic event but the EastEnders cast were also brought together.
The BBC One soap is known for focusing its storylines around ongoing issues across the UK and the Coronation was no exception with royalist Linda Carter going all out.
In recent years, Linda's love for the Royal Family has shone, with the Queen Vic pub decorated in royal memorabilia and her dog being called Lady Di after Diana, Princess of Wales.
Opening the episode, Linda (Kellie Bright), informed local children that it was a "very special day," as it would not have happened during the coronavirus pandemic.
Linda said: "We were all stuck at home on our own weren't we, school online, no weddings or funerals, clapping on the doorstep and putting rainbows in our windows.
"It was a hard time but our Queen said then, she told us on the telly, 'better days will return, we will meet again'."
The landlady went on to say: "And though she may not be here, she was right weren't she, a coronation, ain’t many people who can remember the last time this happened.
"Cos it don't matter what's going on in your own life, don't matter how rich or poor you are, today King Charles III gets crowned and that is tradition.
"In my book, it's part of being British."
Elsewhere in the episode, the residents of Albert Square put their finest outfits on as the kids showcased their impressive crowns for the "best crown" party.
Despite the celebrations, local cab driver Harvey explained that Queen Camilla may be a "lovely lady" but he was unsure whether the elaborate celebrations were necessary during the cost of living crisis – a sentiment which resonated with many Brits.
As the Archbishop of Canterbury lifted the rare St Edward's Crown above King Charles' head, the residents fell silent in the pub, before letting out a loud cheer when the crown was placed on the Monarch's head.
The celebrations come almost a year after the then Prince of Wales and Duchess of Cornwall paid a visit to Albert Square as part of the Queen's Platinum Jubilee celebrations after meeting with Mick and Linda Carter.
