Divide and conquer

Divide and conquer is a political strategy used to gain and maintain power. It works by using divisive measures to break up groups of people. This can involve exploiting existing disagreements within a group. It can also mean deliberately creating new divisions to strengthen them. The primary goal is to prevent opponents from uniting against a common foe. If people are busy fighting each other, they cannot fight the person in charge. This allows one entity to keep control over others.

In English, this concept has several different names. People often use the term "divide and rule," which is common in British English. In American English, "divide and conquer" is the most frequent version. Other variations include "divide and govern" or "divide so that you may rule." The phrase comes from the Latin term "divide et impera." It first appeared in the English language around the year 1600. Some historical figures have viewed this as a tool of tyranny. For example, James Madison called it a "reprobated axiom of tyranny" in 1787.

In politics, the strategy focuses on breaking up power structures. It aims to prevent small groups from linking up to form a large force. By fostering rivalry and discord, leaders can prevent rebellions against the elites. The goal might be to pit lower classes against each other. This prevents a revolution from starting. Alternatively, leaders might use the resulting discord to provide solutions that strengthen their own position. This mechanism ensures that power remains concentrated at the top.

Julius Caesar provided a famous historical example in the conquest of Gaul. The Gauls were many tribes that shared a culture but were politically independent. These tribes often had bitter hatreds for one another due to constant raids. Caesar systematically exploited this lack of centralized authority. He used a system of incentives to ally with some tribes. He used punishments to intimidate others. This ensured he only ever fought one opponent at a time. He even presented himself as a defender of Gallic interests to win over neighbors.

Eventually, the Gauls realized Caesar's true motive was permanent domination. A leader named Vercingetorix of the Arverni rose to unite the tribes. He was an exceptionally high-caliber leader who enforced discipline. He used a strategy of continual retreat and destroyed food to deny Caesar easy battles. However, Vercingetorix eventually sought shelter in the walled city of Alesia. Caesar responded by building a double ring of fortifications. One ring kept the Gauls inside, while the other protected Romans from a relief army. Caesar won a crushing victory at the Battle of Alesia. Vercingetorix surrendered, and the tribes were integrated into the Roman province of Gaul.

Other empires used similar tactics to manage diverse populations. The Mongol Empire sent Han Chinese and Khitans to rule over Muslim populations in Bukhara. This used foreigners to curtail the power of local people. The Ottoman Empire also pitted Armenians against Kurds to maintain control. In British India, some historians argue the British Raj used these methods to prevent an independence movement. They claim the British used the old Roman maxim "divide et impera." However, other historians note that the British Indian Army was actually effectively integrated. These different perspectives show how complex these historical patterns can be.

We can also see these patterns in more modern history and geography. In Cyprus, colonial authorities stirred up the Turkish minority to neutralize the Greek majority. This helped create an animosity that remains on the island today. Some historians believe the 1921 partition of Ireland was an intentional use of this strategy. In economics, the concept is used for market segmentation. This helps businesses get the most out of players in a competitive market. Understanding these connections helps us see how power is managed through division across many different fields.
