Olaus Petri

Olaus Petri was a Swedish theologian and reformer in the 16th century who played a key role in introducing and establishing Protestantism, specifically Lutheranism, in Sweden. He studied in Germany and helped translate the Bible into Swedish, making religious texts more accessible to ordinary people. Petri supported the break from the Catholic Church and worked to reform church practices and teachings, promoting education and literacy. His efforts significantly shaped Sweden's religious landscape, laying the foundation for the Lutheran church as the country's official faith.
