When a state loses its monopoly on violence, the basic deal between people and their government, something known as the social contract, starts to fall apart, and what follows is a slow crisis of governance where insecurity spreads and whole regions slide into chaos.
Power ends up in the hands of warlords, gangs, and militias, and the ordinary person is left to survive on vigilante justice and whatever private security they can afford.
The rot usually shows itself in a few ways.
The rule of law goes first. Once the state stops working, the police and the courts lose their authority almost overnight, and crime, extortion, and banditry rush in to fill the space they leave behind. In most cases, judges and police officers participate in the extortion and corrupt practices.
Then the mini-states appear. Armed groups take territory and run it like their own country, setting the rules, collecting taxes, and handing out punishment to anyone who refuses to go along. Their punishments are usually brutal and may lead to death of their new subjects.
People respond the only way they can, which is to defend themselves. Farmers form patrols. Villages arm their young men. It works for a while, and then it turns, because a group raised to stop violence usually becomes another source of it. This time, targeted on anyone that doesn’t look like them. It turns out our basic instinct is survival, and we often do that in clans.
Underneath all of this, the economy quietly dies. Families flee. Farms are abandoned. Investors read the news and move their money somewhere safer, and the decline starts feeding on itself.
In the end you get a failed state. A government that still has a flag, an army and even a currency but can no longer give its people the one thing a government exists to give: safety.
