On October 17, in the year of grace 1345 (2015), a negotiation between certain members of the West Bohemian nobility was held at the fort Lsteni near the town of Domazlice. The selected noblemen were invited by Mr Ratmir IV of Svamberk to agree upon a mutual alliance and to form a coalition of lords, squires and yeomen of the Pilsen Region who are mutually committed to a common protection of their estate in case of an attack by enemy forces.
The alliance of Ratmir of Svamberk with other nobles, especially with Habart of Lnare and Kasejovice (followed by Rous of Litice, Charles of Svarov and others) thus gave birth to The Pilsen Knightly Association. John of Luxembourg, a Czech king, was present at the main negotiation, having ratified the instituting act by his signature. During the negotiations there was a tournament followed by the knighting of Ota of Karizka in the presence of the monarch.
