Martial Law
In short
A government replaces civilian rule with direct military control, often suspending normal laws and civil liberties. It is typically declared during wars, natural disasters, or periods of extreme civil unrest.
In plain words
The military takes over the running of a country or area. Instead of police and regular courts, soldiers manage daily life and enforce rules. This usually happens when the government feels it can no longer maintain order.
A simple example
During a massive natural disaster that destroys all local government buildings, a leader might declare martial law so the army can distribute food and enforce curfews.
Why it matters
It fundamentally changes how a society functions by removing standard legal protections. It can restore order quickly, but it also risks permanent loss of democratic rights.
Easy to mix up
Do not confuse it with a state of emergency, which may increase police powers without replacing the entire legal system with military rule.
