A rare 17th-century manuscript that played a key role in the restoration of the British monarchy under King Charles II ten years after his father’s execution will be auctioned next month.

One of the two surviving copies will go under the hammer in May at London’s Sotheby’s auction house, just a few days before the coronation of the current monarch, King Charles III, in Westminster Abbey.

“Along with the Magna Carta, it is one of the few documents that has forever changed royalty and is therefore the most important of its kind to be auctioned,” Sotheby’s expert Gabriel Heaton said. “By this proclamation in 1660, the monarchy was restored, and conditions were agreed that are still in force today, 350 years later, when Charles III ascends the throne,” the House of Representatives said in a statement.

An auctioned copy with an estimated price of £400,000 to £600,000 ($500,000 to $750,000) was sent to the Navy, where it was read to the Navy by Samuel Pepys, secretary to Admiral Edward Montagu, in whose family he remained . until the 1960s

After years of exile, planning a series of failed plots and rebellions, Brenda’s Declaration marked Charles II’s chance to seize the throne. He returned to London in 1660 where he ruled for the next 25 years.

On his way back to Britain, he first moved from Catholic Brussels to Protestant Brenda. From there, he issued a proclamation that granted full pardons to many former Democrats, mandated religious tolerance, recognized property rights, and agreed to pay off war debt. As a result, Parliament proclaimed Charles II as King Charles on 8 May, the same day that the proclamation was published in the press.
