Before World war I. First Sea Lord Winston Churchill wanted to name a new battleship after William Pitt. King George V shot that down, saying he had served in the navy and he knew what unflattering nickname sailors would give to a ship named “Pitt”. Churchill also asked for a ship named after Oliver Cromwell, arguing he was the founder of the modern Navy. KGV shot that one down too, don’t name anything after a regicide.
Of course when yo notice how inept the Hanover George’s were (III loses America and goes nuts, IV was a lecherous slime), you wonder how the royal family could keep assigning that name.
