While there are other ways to help you seize power, like being related to a former leader, the general gist is to provide people with incentives to put you in power. And typically, the best incentive just happens to be money.
Spoiler alert: If you're trying to take control of a democracy with the sole intent of turning it into a dictatorship—good luck with that! The older and stronger an institution is (I'm looking at you, Americans and Brits), the harder it is to shrink the massive Coalition. So yeah, you're kind of held at the whim of the people. Sorry about that.
So, rule one is done—the incumbent is gone, and the Coalition is looking at you as their favorite. However, it turns out there are a ton of other people who are also vying for the exact same job you want. Now, it's time to move on to Rule 2, which is: Seize the government.
Now, I know it's kind of redundant for me to say "seize the government" in a video about overthrowing the government, but what I mean is to appear to be in control of the government apparatus. Basically, you need to make sure your group takes control of the government before anyone else.
You can seize the government in one of two ways: you can win the support of the people, but that's really tedious and annoying. A far more common and successful method happens to be using shty shty bang bangs (guns).
Imagine this: You're in a room of 100 people, and five people have shty shty bang bangs. Boom! The five people are in charge of the room. They could be god-awful leaders—chances are, they probably are—but since they have that authority thanks to these weapons, they're able to take control of the room and appear to be in control.
This is exactly what you want to do with the government. Once you get control of the instruments of the state, you'll have a much easier time stomping out your opponents and cementing your position.
Now that you've seized the apparatus of government, crushed your opponents, and have the Coalition leaning toward you loyalty-wise, it's time to form your very own loyal Coalition.
The people who helped you get into power are not going to help you much once you actually hold the office. You don't need revolutionary comrades once the revolution has already been won. So, you can feel free to dispose of them. In fact, I highly recommend you dispose of them because these people have the means and capabilities to take over a government. And last time I checked, you're the government—so they can pose a very capable threat to you and your stability.
Just remember, the most vulnerable time to be a dictator is in the first six months. Over 50 percent of leaders are ousted in this time frame. So, reshuffling your Coalition with new people who are cheaper to buy and more loyal to you will help you out in the long run.
And there you go—you've done it! If you were able to win over the Coalition of the incumbent, seize the government apparatus, and then form your own very loyal Coalition, congratulations—you've taken control of the government.
However, coming to power and staying in power are two very different things that require very different capabilities. You could be great at coming to power, but leading a country is a much different problem.
