隋大业九年(613年)移同安县治于今安徽桐城市治。①属同安郡。②唐武德四年(621年)属舒州。天宝元年(742年)属同安郡。至德二年(757年)属盛唐郡。改名桐城县。③

①《太平寰宇记》卷125舒州桐城县:“县山旧城,按开元二十二年移县出山城前置。其城内丛蓧深密,猛兽为窟,其中兼出毒蛇,邑人久为之患。元和八年县令韩震焚烧草木,裁植松杉,今亦荒废。”“同安故城在县郭东门外。隋大业九年筑。十三年被贼李子通攻陷。因废此城,人因以为名。”(光绪金陵书局本)按:上文所述。隋大业九年(613年)所筑之城,在唐开元二十二年以后桐城县城东门外。在图中两县治可视为一地。《清嘉庆一统志》第36册,卷110《安庆府二古迹》:“《县志》:宋末移桐城县治枞阳镇。后又移治池州之李阳河。元时始还旧治。”“旧治”当即指唐宋桐城县治,即今桐城县治也。道光七年《桐城续修县志》卷4《营建志》:“城郭,县旧有城,即隋同安县故址。……历宋元城经两徙,故城倾圯。明万历丙子,知县曲周陈于偕……建造砖城,……今仍其旧。”可知隋后之桐城县治即今治也。
②《隋书》卷31《地理志下》:同安郡:“开皇初曰熙州。……怀宁,旧置晋熙郡。开皇初郡废。大业三年置同安郡。……同安,旧曰枞阳,并置枞阳郡。开皇初郡废,十八年县改名焉。”(第3册,876页)
③《旧唐书》卷40《地理志三》舒州“隋同安郡。武德四年改为舒州,领怀宁、宿松、太湖、望江、同安五县。……天宝元年改为同安郡。至德二年二月改盛唐郡。乾元元年复为舒州。”(第5册,1582页)《新唐书》卷41《地理志五》:舒州“桐城,本同安,至德二载更名。”(第4册,1054页)", "source uri" : "" }
