Medieval Hamburg

In 834, Hamburg was designated as the seat of a bishopric. The first bishop, Ansgar, became known as the Apostle of the North. Two years later, Hamburg was united with Bremen as the Bishopric of Hamburg-Bremen.

Hamburg was destroyed and occupied several times. In 845, 600 Viking ships sailed up the River Elbe and destroyed Hamburg, at that time a town of around 500 inhabitants. In 1030, King Mieszko II Lambert of Poland burned down the city. Valdemar II of Denmark raided and occupied Hamburg in 1201 and in 1214. The Black Death killed at least 60% of the population in 1350. Hamburg experienced several great fires in the medieval period.

In 1189, by imperial charter, Frederick I "Barbarossa" granted Hamburg the status of a Free Imperial City and tax-free access (or free-trade zone) up the Lower Elbe into the North Sea. In 1265, an allegedly forged letter was presented to or by the Rath of Hamburg. This charter, along with Hamburg's proximity to the main trade routes of the North Sea and Baltic Sea, quickly made it a major port in Northern Europe. Its trade alliance with Lübeck in 1241 marks the origin and core of the powerful Hanseatic League of trading cities. On 8 November 1266, a contract between Henry III and Hamburg's traders allowed them to establish a hanse in London. This was the first time in history that the word hanse was used for the trading guild of the Hanseatic League. In 1270, the solicitor of the senate of Hamburg, Jordan von Boitzenburg, wrote the first description of civil, criminal and procedural law for a city in Germany in the German language, the Ordeelbook (Ordeel: sentence). On 10 August 1410, civil unrest forced a compromise (German: Rezeß, literally meaning: withdrawal). This is considered the first constitution of Hamburg.

In 1356, the Matthiae-Mahl feast dinner for Hanseatic League cities was celebrated for the first time on 25 February, the first day of spring in medieval times. It continues today as the world's oldest ceremonial meal.
