How do historians support their conclusion?

Historians support their conclusions by critically analyzing primary and secondary sources, including documents, artifacts, and previous scholarly works. They evaluate the reliability and context of these sources, considering factors such as authorship, purpose, and audience. Additionally, historians often cross-reference information to establish a more comprehensive understanding of events and trends, while also engaging in peer review to refine their interpretations. This rigorous methodology helps ensure that their conclusions are well-substantiated and credible.
