No Polish Religious Freedom Law

IOTL, the Polish Lithuanian Commonwealth was a (relatively) tolerent nation. Jews, Protestants, Catholics, and even some legal resident Muslims lived side by side. But WI Poland became instead an extremist Catholic state like 15th-16th century Spain? Any POD is good, as long as it's before 1550.
 
Maybe a survival of Ladislav III:confused:. He led a crusade against the Turks, and if he had survived (and perhaps kept Hungary in the union as well, shifting the number of catholics even higher) it might have led to a less tolerant Poland.

An Hapsburg marriage might be needed as well.
