Okay, so there was this thing called the archpriest controversy. It sounds like a big word, but basically it was just a fight over who had control of the churches in England a long time ago.
See, there were some people who thought that the government should have a say in who got to be a priest and how they ran the church. But there were other people who thought the church should be left alone to do their own thing without interference from the government.
This argument got pretty heated, with both sides accusing each other of doing bad things. Some priests were even put in jail for not following the rules.
Eventually, the government decided to make a compromise. They said that the Archbishop of Canterbury (who was a really important church leader) would have more power over the priests, but the government would still have some say in how things were done.
So in the end, everyone kind of got what they wanted, but it took a lot of arguing to get there.
