I would not capitalise, for any title that I can think of.

I would not capitalise, for any title that I can think of.

Generally, if the title is associated with or used in place of a proper name, it would be capitalized; here are some examples from The Chicago :
General Eisenhower
President Buchanan
Prince Charles
Cardinal Newman

You did well, Captain, to avoid that sea lane.
Ladies and gentlemen, the President of the United States.

A peculiar exception they note there is the Speaker of the House of Representatives of the United States presumably to avoid confusion with someone who happened to be orating there. Other such exceptions are General of the Army, Fleet Admiral, and some British titles (the Prince of Wales, the Queen Mother, the Princess Royal, and the Dame of Sark (look that one up some time).
Honorifics are normally capitalized: Her Majesty, Your Grace, Your Honor. Some epithets are also tradirtionally capitalized: the Great Emancipator, the Wizard of Menlo Park, Babe Ruth, Stonewall Jackson (arguably those are proper names), the Sun King, and a few others of that sort.

A little confusing.
Ok, in my manuscript I talk of Kings, Queens, Princesses and Dukes.

If I write, "The princess said she'd be there" is the ruling saying "princess" should be capital because I'm talking about a specific princess?

Likewise, duke?
