Creator Peter Morgan says this extra season will enable the show to cover the same period in greater detail.
The Crown's reign on Netflix has been extended.
The hit drama had originally been set to last for six seasons, but in January its creator Peter Morgan revealed that it would end on five, which he said at the time was the "perfect time and place to stop." Morgan has now gone back on this decision, confirming alongside Netflix that the show will indeed close on six.
"As we started to discuss the storylines for series five, it soon became clear that in order to do justice to the richness and complexity of the story we should go back to the original plan and do six seasons," he said.
However, any hopes that the extra season will bring us closer to the present day and recent royal upheavals, including Prince Andrew's associations with Jeffrey Epstein and Prince Harry and Meghan Markle's so-called "Megxit," have been dashed.
"To be clear, season six will not bring us any closer to present day — it will simply enable us to cover the same period in greater detail," said Morgan.
