805 in history

Died in 805

Feb 25 Emperor Dezong of Tang an emperor of the Chinese Tang Dynasty and the oldest son of his father Emperor Daizong. His reign of 26 years was the third longest in the Tang dynasty. Emperor Dezong started out as a diligent and frugal emperor and he tried to reform the governmental finances by introducing new tax laws. His attempts to destroy the powerful regional warlords and the subsequent mismanagement of those campaigns, however, resulted in a number of rebellions that nearly destroyed him and the Tang Dynasty. After those events, he dealt cautiously with the regional governors, causing warlordism to become unchecked, and his trust of eunuchs caused the eunuchs' power to rise greatly. He was also known for his paranoia about officials' wielding too much power, and late in his reign, he did not grant much authority to his chancellors
May 12 Æthelhard a Bishop of Winchester then an Archbishop of Canterbury in medieval England. Appointed by King Offa of Mercia, Æthelhard had difficulties with both the Kentish monarchs and with a rival archiepiscopate in southern England, and was deposed around 796 by King Eadberht III Præn of Kent. By 803, Æthelhard, along with the Mercian King Coenwulf, had secured the demotion of the rival archbishopric, once more making Canterbury the only archbishopric south of the Humber in Britain. Æthelhard died in 805, and was considered a saint until his cult was suppressed after the Norman Conquest in 1066
