The outcome of the election was strongly contested by factions of the Polish nobility that backed the candidacy of Archduke Maximilian III of Austria, who launched a military expedition. When the news reached Sigismund in Sweden, he passed through the clutches of the Protestants, crossed the Baltic and landed in Poland on 7 October, immediately agreeing to grant royal privileges to the Sejm (parliament) in the hope of calming the opposition and settling the disputed election. He was proclaimed king by Treasurer Jan Dulski on behalf of Crown Marshal Andrzej Opaliński, and after arriving in the Royal Capital City of Kraków he was crowned on 27 December at Wawel Cathedral.
