Modern history is an empirical historical study.

 Based on some literature, various theories such as the Continental Goguryeo theory come out...But most of these theories come from amateur historians, not orthodox historians, honestly speaking... Those who argue this theory argue that the mainstream historical community is stained with something lame and wrong values and that they think of the real truth and think of their theories. However, there is a reason why historical circles ignore their theories...I'm not even interested in it because it's a major flaw in theory... Most of those theories have fatal weaknesses that they can't be verified...Then some might wonder if history is any science, but history is definitely a social science... In the 20th century, modern history introduced a methodology of natural science, making it the mainstream of historical studies has become the mainstream of history. Historical theory is considered one of many hypotheses, not orthodox, if there is no evidence such as artifacts to support and verify it...Ancient historical records, which are considered reliable, often reinterpret based on evidence of new reliability... ...that is, to revise the orthodox theory of the existing orthodox historical world, support the new theory and verify it by the same procedure.In other words, a solid theory with objectively verifiable archaeological evidence is controversial in the orthodox historical world along with the existing theory... ...the last time in Japan, a famous historian forged ancient artifacts...That person does that because his theory needed evidence to be recognized as orthodox in history...However, because there is no evidence, self-theory is not treated properly, so he forged the evidence on his own...Until the fraud was revealed, the Japanese professor's theory of ancient Japanese history became quite controversial in Japanese history...The reason was that it was a theory that could be demonstrated... Of course, fraud has been discovered now, and only Japanese history has been humiliated... If you turn it around, it's an event where you can see how much evidence is in modern history... It's not just a joke in mainstream history.
