We just learned about the Devshirme.
Another part of early Christianity was the Gutenberg Bible.
Long ago when people wanted to make a copy of the Bible they had to write it out by hand.
It was not very easy to make paper, ink or pens, so it took a long time, and each copy looked very different depending on who was writing it and what the paper or pen looked like.
Around 1450 people were using something called a Printing Press that was like a big stamp with a roller of paper that could print a lot of copies quickly.
In Germany a man named Johannes Gutenberg used the printing press to make about 150 copies of the Bible, and send them around Germany.
This started a big change in the world of Christianity because a lot more people could read the actual words in the Bible and learn for themselves about God and Jesus.
