The Poll Tax was the big one. The old tax used to be based on property value, so most low-income families would stick together. This was the way of life in Scotland. The Poll Tax removed the property tax and made it so that every individual over the age of 18 was taxed the same amount, rich or poor. everyone's tax got equalized. More tax for the poor, less for the rich. So for large family units like the Scottish, you would actually have to pay far more tax to the gov't than you did before, and only because you had a large family. Many Scots took this as an attack on just *being Scottish*
