Olaus Martini

Olof Mårtensson (1557 – 17 March 1609) also known by the Latin form Olaus Martini, was Archbishop of Uppsala from 1601 to his death.

On returning, he made a reputation for himself when he criticized the liturgy of Swedish King John III, who held somewhat Catholic beliefs despite Sweden having been Lutheran since 1531.

Despite his support, Martini was fundamentally in opposition to the beliefs of duke Charles, a conflict which eventually led to disputes between the two.

Martini was an orthodox Lutheran, while Duke Charles is believed to have been inclined towards Calvinistic tenets—which he himself denied (see: crypto-Calvinism).

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.
