The Legend of the Slavic Brothers
They certainly do know this. Usually they would spell it Lechistan, though. It hearkens back to an old legend of three Slavic brothers Lech, Czech and Rus. They were having a drink of local beer in Poznań when they realised that they each wanted to father a nation. In order not to get in each other’s way they decided Czech would go south and Rus would go east. Lech on the other hand would stay in Poznań and look after the local brewery, which bears his name to this day.
He regularly would become plastered on his own product, and thus became known as the “protoplasta Polaków”. Among his achievements is setting up a capital city in Gniezno, a form of the old Polish word for a nest, and from this nest the Polish nation was fledged.
Czech and Rus fathered the nations named after them, while Lech fathered the Polish nation. He became the patron saint of Polish beer, and of big moustaches, and of smashing up invaders such as Islam or Communism.
Various Lechs and Leszeks
As well as a full-sized Lech you also get diminutive ones, namely Leszek, although linguistically speaking, Leszek is a lexicalised diminutive of Lech. You can add it to your lexicon, or Lech’s icon if you happen to be honouring the Patron saint, whose saint’s day is on the 28th February with another go on 12 August if you missed the earlier one.”
