The Mongols raid Bitom, one of the oldest cities of Upper Silesia.
Chartered by Bohemia only five years earlier, the city had grown owing to its location on a strategic crossroads.
(The city, slowly Germanized from the fourteenth century, will become known as Beuthen but will see its German population expelled in the aftermath of the Second World War.
Today known as Bytom, it is one of the main cities of Poland’s Upper Silesian Metropolitan Union.)
