Answer 2

@Reed

I shouldn't of copied and pasted the whole question since it was just the last part. From the text it states "Turner began by noting that the 1890 census no longer discerned a clear frontier line. So I am guessing it was the 1890 census.

Answer 3

That may well have been what prompted him to write his essay. I'd go with that. His thesis is that the frontier created American democracy, not that the frontier continued to exist as it had since the first European settlers arrived.

Answer 4

@Reed

so I am simply stating that prompted by the 1890 census he suggested theclosing of the frontier meant an end to the development of American democracy
