I want to know the answer to the following question:
What stopped after the death of Sigismund II Augustus?
All the background I'm provided with is that "Every newly elected king was supposed to sign two documents—the Pacta conventa ("agreed pacts")—a confirmation of the king's pre-election promises, and Henrican articles (artykuły henrykowskie, named after the first freely elected king, Henry of Valois).". Is that enough to answer the question?
Answer: no
