The title automatically passed to The King on his accession
His Majesty King Charles III will be proclaimed as Lord of Mann on Sunday (11 September).
The Proclamation will be read by the Lieutenant Governor, Sir John Lorimer, at Government House in Onchan at noon.
There will also be a second Proclamation Ceremony at 11am on Friday 16 September, which will be made from Tynwald Hill in St John's, the ancient seat of the Kings and Lords of Mann.
It will be based on the one held there in February 1952 to proclaim Queen Elizabeth II, and will be similar to the normal Tynwald Day Ceremony.
After this, a resolution of loyalty and condolence will be put before a sitting of Tynwald Court in the Royal Chapel.
Members of the public are welcome to witness the proceedings on the Hill, with sound amplification put in place as far as possible.
Manx Radio is also broadcasting the event live, and it will be streamed online.
