I want to know the answer to the following question:
After 1573 who could become a polish-lithuanian monarch?
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?
