Nicholas Zebrzydowski, a follower of the chancellor Zamoyski, was one of the wealthiest and most respectable magnates in Poland.
On the 7th of March 1606 Sigismund summoned a diet for the express purpose of introducing the principle of decision by majority in the diet, whereupon Zebrzydowski summoned a counter-confederation to Stenczyn in Little Poland, whose first act was to open negotiations with the prince of Transylvania, Stephen Bocskay, with the view of hiring mercenaries from him for further operations.
At a subsequent confederation, held at Lublin in June, Zebrzydowski was reinforced by another great nobleman, Stanislaus Stadnicki, called the Devil, who "had more crimes on his conscience than hairs on his head," and was in the habit of cropping the ears and noses of small squires and chaining his serfs to the walls of his underground dungeons for months at a time.
Despite their promises, Zebrzydowski and his colleagues a few months later were again in arms. In the beginning of 1607 they summoned another rokosz to Jendrzejow, at the very time when the diet was assembling at Warsaw.
This most simple and salutary reform was, however, rendered nugatory by the opposition of Zamoyski, and his death the same year made matters still worse, as it left the opposition in the hands of men violent and incapable, like Nicholas Zebrzydowski, or sheer scoundrels, like Stanislaw Stadnicki.
See Aleksander Rembowski, The Insurrection of Zebrzydowski (Pol.) (Cracow, 1893); Stanislaw Niemojewski, Memoires (Pol.) (Lemberg, 1899); Sveriges Historia, vol.
During the insurrection of Nicholas Zebrzydowski he led the army which routed the rebels at Guzow in 1607, though protesting against the necessity of shedding "his brothers' blood."
Sometimes, as for instance during the insurrection of Zebrzydowski, Skarga intervened personally in politics, and on the side of order and decency, for his loyalty to the crown was as unquestionable as his devotion to the Church.
