Divide and rule- An old policyDivide and rule (Latin: Divide et impera) is an old technique to empower the ruler to control subjects or people who oppose the ruler or might be a big threat to the ruler in future. So, it's aimed to break their unity.
Divide et impera is attributed to Philip II of Macedon and it was used by Julius Caesar, the Roman emperor.
By this technique division is created among the people of the country through different sources by creating Misunderstanding, controversies, disputes based on sensitive issues like religion, caste, creed, ideology, language, region etc.
Media, men, money, muscles are used to spread false propaganda, threaten the opponent groups, allure some factions and crush the protest or agitation respectively. Main opponents are harassed, intimidated and sometimes, are enmeshed in false cases.
Thus common people forget the core issues and they begin to focus on useless ones instead.
