Edited sentence: China's claim on Goguryeo's history is nothing more than a political attempt.First, Goguryeo started within Gojoseon territory & Gojoseon people in Manchuria.Goguryeo's direct lineage (in government, ruling class & general ethnicity) is Korean in North Korea.In general perception & by how we humans define history, history is about the story of people.Second, Goguryeo's government & its ruling people moved into North Korea a couple hundreds years before Goguryeo was destroyed.The transition from Goguryeo to Korea is a direct & main transition.Therefore, Goguryeo's history doesn't belong to China but to Korea.Third, regardless of Columbus being Italian, the history of USA & Columbus belong to USA, not Italy
