koreanhistory1-4, Exercise 3: Contradictions (a sample; yours will differ)

Model answer:

1. Result of the Silla-Tang War: "Silla victory" (infobox) vs "ended in a truce" (lead). Check a source that describes the settlement; do not conclude either alone, since both can be true (Tang left the south but the north stayed Tang-held).
2. Balhae's fall: 14 January 926 (infobox) vs a Buyeo siege from 14 February with the capital besieged six days later (body). Check a source that dates the Khitan campaign; do not conclude a month without it.
3. Balhae refugees: 120,600 is "approximately 6.3%" of about 2 million, but the arithmetic gives nearer 6.0%. Check the original figures; do not conclude the percentage or the population from the article alone.
4. Unified Silla's periodisation: the infobox splits it at 892 ("United Silla 668-892" and "Later Silla 892-935") while the body treats it as one period; also the Later Three Kingdoms starts are 889, 892 or 900. Check how a cited work divides the period; do not take the infobox split as a historical event.
Also: the Cheonseong date "765", Xue Rengui vs Liu Rengui, Liaoyang vs Liaodong, the 713 vs 762 recognition of Balhae.
