Martin Luther's ideas played a big role in changing religion in Sweden during the Protestant Reformation. He believed that people could be saved through faith alone. This idea struck a chord with many Swedes who thought the Catholic Church was corrupt and didn’t connect with regular folks.

1. How Luther’s Ideas Spread:

   • Luther wrote the 95 Theses, where he pointed out problems like the selling of indulgences.
   • His thoughts spread quickly in Sweden, thanks to the new printing press and conversations among people.

2. Support from Important Leaders:

   • Powerful people, like the king, backed the Reformation. This helped Protestantism take root in Sweden.
   • As a result, many monasteries were closed down, and church land was handed to others.

3. Lutheranism Takes Hold:

   • By the late 1500s, the Church of Sweden officially became Lutheran. This changed everyday life and culture in the country.
   • Church services were now held in Swedish instead of Latin. This made it easier for everyone to understand.

In summary, Luther's teachings helped Sweden move from Catholicism to a Protestant faith, which changed the country’s identity forever.
