The opposition hoped to thwart the match with Archduchess Anne of Habsburg, who made her state entry into Kraków amidst great rejoicings at the end of May. Sigismund disregarded any protest in regards to the marriage. Consequently, on 1 June 1592 Zamoyski formed another confederation at Jędrzejów (Latin: Andreiow) attended by the most eminent and distinguished magnates, among them Mikołaj Zebrzydowski and Stanisław Żółkiewski. At Andreiow, he allegedly exposed proof concerning a plot that would place Archduke Ernest on the throne if Sigismund was to abdicate. Zamoyski's claim caused an uproar.
