Suleiman al-Tajir, Muslim merchant and traveller, visits
China during the
Tang Dynasty. He observes the manufacturing of
Chinese porcelain at
Guangzhou, and writes of his admiration for its transparent quality. Suleiman also describes the
mosque at Guangzhou, its
granaries, its local government administration, some of its written records, and the treatment of travellers, along with the use of ceramics,
rice wine, and tea (approximate date).
Treaty of Angers: Charles the Bald meets Erispoe in
Angers, and acknowledges him as "king of Brittany". He recognizes the authority of Breton rule over the areas around
Nantes,
Rennes and
Pays de Retz, which become part of the
Breton March, a border zone. Erispoe takes the
oath to Charles as king of the
West Frankish Kingdom (but not an hommage lige which would be an
allegiance). To mark the sovereignty of the Breton state, the future
Dukes of Brittany are crowned as "Duke, king in their lands".[5]
Emperor
Lothair I meets with his (half) brothers
Louis the German and Charles the Bald in
Meerssen (modern-day
Netherlands), to continue the system of "con-fraternal government".
