source note: 延昌县(742-) (起止年份待校正) 唐天宝元年(742)改罢交为延昌,属延安郡。乾元元年(758)属延州。①唐末废。②治今陕西安塞县化子坪。③ 注: ①《旧唐书》卷38?志第十八?地理一?延州中都督府:隋延安郡。武德元年,改为延州总管府,领肤施、丰林、延川三县,管南平、北武、东夏三州。四年,又管丹、广、达三州。贞观元年,罢都督府。开元二年,复置都督府,领丹、绥、浑等州。天宝元年,改为延安郡。干元元年,复为延州。……延昌,武德二年,置北平州。贞观三年废,十年于废州置罢交县。天宝元年,改名为延昌县。(中华书局,1975 年,5 册,1410 页) ② 此县不见载于《太平寰宇记》,疑为唐末废。 ③《嘉庆重修一统志》卷234?延安府?古迹?安塞故城,在安塞县北。(《四部丛刊续编》,商务印书馆,1934 年,14 册)今陕西省安塞县北化子坪乡,古称罢交镇,疑是。
