Any reason behind the ending of Inglourious Basterds?

This is about the movie - Inglourious Basterds

This movie takes the (possibly) actual failed attempt to assassinate Hitler in a movie theater (I'm not able to find any data for the real-life attempt) and flips the story around to a successful assassination.

Any particular reason this was done and that particular event from history was chosen?

The answer to your question is:

Tarantino himself has remarked: "In this story, cinema changes the world, and I fucking love that idea!"

The reality is; There was never an assassination attempt on Hitler in a theater. Though much of the film loosely follows history, the movie itself is not meant to be historical or biographical. Tarantino just thought the idea of a world-changing event happening in a theater sounded cool, so he moved the demise of Hitler to a cinema.
