Convention of Uppsala

The Convention of Uppsala in 1593 was a pivotal event in Swedish history, solidifying the country's commitment to Lutheranism. Following the Protestant Reformation, King Gustav I Vasa had initiated the break from the Roman Catholic Church, confiscating church properties and establishing the Church of Sweden as independent and Lutheran in 1527 and officially in 1544.123

However, when Sigismund III Vasa, who was Roman Catholic and spent much time in Poland, inherited the Swedish throne in 1592, opposition grew. In response, a declaration was adopted by the clergy at Uppsala in 1593, definitively confirming Sweden as a Lutheran country. This event was crucial in shaping Sweden's religious and national identity, ultimately leading to Sigismund's resignation in 1599.23
