Death of Stefan Batory began a third period of interregnum in 15 years. The Commonwealth was left without a monarch, since Anna Jagiellon, who was regarded as co-ruler of the country, had relinquished her claims to the crown. As a result, Poland - Lithuania was again ruled by an interrex, Primate and Archbishop of Gniezno, Stanisław Karnkowski, who organized the election and met with foreign envoys. At that time, the Commonwealth was deeply divided between the powerful magnates and the szlachta. Stefan Batory had been backed by noble families, while szlachta accused him of tyranny. Furthermore, there were internal divisions between Polish Crown and the Grand Duchy of Lithuania, also between Polish provinces. The Convocation Sejm began on February 2, 1587, and was immediately marred by arguments between the magnates and the nobility. , painting by Hans Henseiller.
Candidates
The Convocation Sejm began on February 2, 1587, and was immediately marred by arguments between supporters of four camps: Habsburg, Swedish, Muscovy and those who backed a Piast, or a native citizen of the Commonwealth. The Habsburg candidate was supported by the Zborowski family, Voivode of PoznańStanislaw Gorka, Bishop of VilniusJerzy Radziwiłł, and Sejm MarshalStanislaw Sedziwoj Czarnkowski. All received large sums of money from Emperor Rudolf II, but an ultra-Catholic, Habsburg candidate was regarded as a threat to religious tolerance, guaranteed by Warsaw Confederation. Another possible candidate, Tsar Feodor I of Russia was supported by the Lithuanians, who hoped that his election would end never-ending wars between Muscovy and Grand Duchy of Lithuania. A Piast candidate was liked by the Poles, but opposed by the Lithuanians. Swedish/Jagiellon candidate, Duke Sigismund, son of Katarzyna Jagiellonka and Swedish King John III, was backed by Anna Jagiellon and one of the most powerful magnates of the Commonwealth, Jan Zamoyski. A Swedish king would guarantee freedom of Baltic Sea shipping, a Polish - Swedish alliance, aimed at Muscovy, and annexation of Estonia by Poland-Lithuania.
The Election
Election Sejm was summoned to Wola on June 30, 1587. Polish and Lithuanian magnates came there with their own armed units, and electors were divided into two camps: pro-convocation, with the Zborowski brothers as their leaders, and anti-convocation, headed by Jan Zamoyski. For the first weeks, the Sejm was occupied by the death of Samuel Zborowski, and arguments between the Zborowski family and Jan Zamoyski. Since Zamoyski did not want to respond to any questions, rokosz was declared, with the purpose of judging Zamoyski and other officials, connected to the late King Stefan Batory. On July 27, both camps began preparation for military action, and at the last moment, the conflict was defused by Primate Stanisław Karnkowski, Voivode of SandomierzStanislaw Szafraniec, and Bishop of Kamieniec Podolski, Wawrzyniec Grzymała Goślicki, who mediated between the two warring parties. In early August 1587, Swedish envoy Erik Larsson Sparre came to Wola, giving a speech, in which he praised Duke Sigismund. His speech impressed the nobility and the magnates, including Zamoyski, Karnkowski, Crown Marshal Andrzej Opalinski, and Albert Laski. On August 19, the Primate nominated Sigismund to the throne, but three days later, the pro-convocation camp declared Maximilian III, Archduke of Austria new king of Poland. Both Sigismund and Maximilian accepted Polish throne, which resulted in the War of the Polish Succession.
After the Election
On September 27, 1587 in Olomouc, Maximilian Habsburg took on the title of King of Poland and Grand Duke of Lithuania, and swore to observe the pacta conventa. After several weeks, he entered the Commonwealth with an army of some 5,000. Maximilian planned to capture Kraków, but failed to do so, and gave up the siege on November 30. On August 24, Swedish envoys Erik Brahe and Erik Larsson Sparre swore the pacta conventa, without waiting for Duke Sigismund, who was on his way from Sweden. Swedish candidate anchored at Gdańsk on September 29, and was welcomed by Bishop of Przemysl, Wojciech Baranowski. Following his father’s order, Vasa stayed on the ship, as he disagreed with one of Polish conditions, which was incorporation of Swedish-ruled Estonia into the Commonwealth. Finally, on October 7, Sigismund Vasa swore to observe the pacta conventa at the Oliwa Cathedral, and on December 9, 1587, he entered Kraków, where he was crowned on December 27. On January 24, 1588, the army of Maximilian Habsburg was defeated by Jan Zamoyski in the Battle of Byczyna. Maximilian, together with his court, was interned in Krasnystaw. The conflict was ended in early spring of 1589, during the so-called Pacification Sejm. Supporters of Maximilian swore their allegiance to Sigismund, and were allowed to return to the Commonwealth.
