Preventing another King George
Stopping Tyranny in 4 different ways
Federalism
In the compound government federalism, the power is split up into two pieces. Power that is given to the central (national, federal) government and power given to the state government. The central government deals more with laws that have something to do with other countries (immigration, army related things, trade.) On the other hand, The state government deals more with personal issues like marriage, schools, and regulate in state businesses. This shows that not the state or central government can form a tyranny.
Big States Vs. Small States
The big states wanted to have representatives based on population (1 for every 30,000.) The small states wanted to have equal representation in government no matter how many people were in your state. They compromised so that they would have 2 houses. In the house of representatives, the big states benifitted because they got more representation if they had more population. In the senate, the small states benefited because they didn't have to worry about the big states becoming tyrants (there was equal representation in the senate.) Once again, this divides the power up so that there won't be a tyranny.
Separation of powers
To prevent a tyranny, Madison had the idea of splitting up the government into 3 different branches. That way, all the power isn't under just a few people. It divides the power equally among the 3 branches. All in all, there won't be a tyranny with the power split up evenly like this.
Checks and Balances
The final way to make sure a tyranny doesn't occur is checks and balances. Basically, in case on of the branches of government does something crazy, the other 2 branches can stop it. For example, if the executive branch does something absolutely crazy, then the legislative branch can impeach the president. This clearly shows that it is almost impossible to have a tyranny with the power in a ton of people's hands.
