Okay kiddo, so here's the deal with the papal jurisdiction act of 1560. Back in those olden days, the Pope was like the big boss of the Catholic church, and he had a lot of power over people. But in Scotland, some folks didn't like that the Pope had so much control over their country. So they decided to make a law called the papal jurisdiction act.
This law basically said that the Pope couldn't boss people around in Scotland anymore. It also said that nobody could pay taxes or follow orders from the Pope without getting in trouble with the government. This made a lot of people happy because they wanted to have more freedom to do what they wanted without being told what to do by the Pope.
Now, this law did cause some problems too. Some people were really upset by it and thought it was disrespectful to the Catholic church. But overall, it was an important step towards making Scotland its own independent country with its own laws and rules.
So, to sum it all up, the papal jurisdiction act was a law that stopped the Pope from having too much power in Scotland and allowed people to have more freedom to live their lives as they wanted.
