How would the us be different if Jefferson never bought louisiuna territory?

Answer 1

We can only speculate about the consequences if Jefferson had not bought the Lousiana territory from France. Possibly that territory would today be a separate country from the United States, and perhaps the states west of the Louisiana territory would never have been taken away from Mexico. Mexico would therefore today be a much larger, and much more powerful nation, while the much smaller United States, existing only east of Lousiana, would be much smaller and weaker than it turned out to be as a result of the Louisiana Purchase. But alternatively, it may well be that even if the US had not bought the Louisiana Territory, the US would eventually have aborbed it anyway, either with the consent of its inhabitants, or by force, and history would have turned out much the same. Or, I could also imagine that the US would eventually seize Louisiana from France, and would wind up going to war with France, and then in WW I would not want to come to the aid of France due to lingering resentments over the Louisiana War, and perhaps would either side with Germany, or more likely remain neutral. And if the US had not entered WW I, the consequences are tremendous. So, there are all sorts of possible consequences, but there really is no way to know what would have actually resulted.

Answer 2

It was a French colony. So you could reason that it might have remained French until somewhere in the 20th century, and that French would now be the spoken language there. On the other hand, it is impossible to say how things would otherwise have developed in the last two centuries under the influence of e.g. the Civil War or France's crushing defeat in the Franco-Prussian war. It might have become part of the US in the first instance, or part of the German Empire in the second case. Who knows?
