According to the Institute of Texan Cultures, history is story—written or carved, painted or sung—a collection of events, often explained and interpreted, somehow always important.
History cannot repeat itself, and it cannot be tested like science can.
In history, proof is everything. There must be reliable witnesses, logical possibility, observable causes and effects, and all facts must be consistent.
History can be primary - someone who was a witness or a participant in an event, or secondary - record made by someone not present at an event, but who uses primary and other secondary sources as evidence.
