Alternative history is a fantasy genre dedicated to modeling the reality that could have been if this or that event had not happened or had a different result.
This genre, like any fantasy in general, is beautiful with a high degree of freedom for reflection, but at the same time with the presence of some kind of framework. It turns out not just chaos, but still something ordered by logic, although still fantastic. We can go even further and speculate in the style of "what if ..." not only on historical topics.
