Career
Born in Uppsala, Sweden, he first enrolled in the University of Uppsala, but when it was temporarily closed in 1578 he travelled abroad. In 1583 he got a Master"s degree at the University of Rostock and then travelled home again. On returning, he made himself a reputation when he criticized the liturgy of Swedish King John III who held somewhat Catholics beliefs despite that Sweden had been Lutheran since 1531.
The king"s brother Duke Charles, who later became King Charles IX, promoted Olaus to becoming Archbishop of Uppsala in 1601.
Despite his support, Martini was fundamentally in opposition to the beliefs of duke Charles, a conflict which eventually led to disputes between the two. In 1606 Martini had a text published which was sharply polemicing against Catholic and Calvinistic tenets.
Although he was in opposition to the King and the Duke, he was considered a hard working and trustworthy man by the University of Uppsala and by his communion.
