> The state didn't magically disappear in 1920, it just went from being administered by the Ottoman sultan to being administered by the British

There was not a Palestinian state in the Ottoman empire. The early 20th century Ottoman division of Sanjaks looked like this:

You could say that the Sanjak of Jerusalem, Sanjak of Balqa, and Sanjak of Acre together pretty much make up the bulk of the area that the British called Mandatory Palestine. But its borders don't match Mandatory Palestine borders, and there was no special association of those three Sanjaks anyway.

Before the 20th century, the Arabs did not use the term Palestine, and had no concept of the areas of modern Palestine as being united in any modern sense. The closest thing that the Arabs at the time would group them would be as Greater Syria or AlShaam (or Ashshaam the way the locals say it), which includes Syria, Lebanon, and most of Jordan - but does not include the Negev desert. The earliest use of the word Palestine by an Arab was 1911, in the founding of the Palestine Post newspaper. At the time the word was a geographic area. The earliest mention of a Palestinian as a demonym for a person (as opposed to a geographic area) was 1964.
