Divide and conquer


The term divide and conquer in politics refers to an entity gaining and maintaining political power by using divisive measures. This includes the exploitation of existing divisions within a political group by its political opponents, and also the deliberate creation or strengthening of such divisions.

Definition

The concept primarily refers to the practice of creating divisions between opponents to prevent them from uniting against a common foe, allowing the one who divides to gain or maintain political control. As a maxim, it is commonly recommended to political rulers. A secondary usage of the idea refers to the practice of "dividing one's own forces or personnel so as to deal with different tasks simultaneously." The exact wording of the idiom in English is varied, including divide and rule, divide and conquer, divide and govern, and divide so that you may rule.

Etymology

The phrase "divide and conquer" first appeared in English around 1600.
Edward Coke denounces it in Chapter I of the Fourth Part of the Institutes of the Lawes of England, reporting that when it was demanded by the Lords and Commons what might be a principal motive for them to have good success in Parliament, it was answered: "Eritis insuperabiles, si fueritis inseparabiles. Explosum est illud diverbium: Divide, & impera, cum radix & vertex imperii in obedientium consensu rata sunt."
In a minor variation, Sir Francis Bacon wrote the phrase as separa et impera in a letter to James I of 15 February 1615. James Madison made this recommendation in a letter to Thomas Jefferson of 24 October 1787, which summarized the thesis of Federalist No. 10: "Divide et impera, the reprobated axiom of tyranny, is under certain qualifications, the only policy, by which a republic can be administered on just principles."
Divide et impera is the third of three political maxims in Immanuel Kant's Perpetual Peace, Appendix I, the others being Fac et excusa and Si fecisti, nega : Kant refers to these tactics when describing the traits of “despotic moralists."

Politics

In politics, the concept refers to a strategy that breaks up existing power structures, and especially prevents smaller power groups from linking up, causing rivalries and fomenting discord among the people to prevent a rebellion against the elites or the people implementing the strategy. The goal is either to pit the lower classes against themselves to prevent a revolution, or to provide a desired solution to the growing discord that strengthens the power of the elites.
The principle "divide et impera" is cited as a common in politics by Traiano Boccalini in La bilancia politica.

Economics

In economics, the concept is also mentioned as a strategy for market segmentation to get the most out of the players in a competitive market.

Historical examples

Roman Empire

In his history of the Gallic Wars, Commentarii de Bello Gallico, Julius Caesar narrates the following episode:
Translated into English, this reads:
The Gauls were a people who shared a language and culture but were politically independent from one another, being separated into a number of tribes. Their interests frequently being at odds, and with existing populations being disrupted by large-scale migrations of other peoples being commonplace, warfare between the tribes was endemic; mostly simmering at a low level in the form of constant raids, but occasionally erupting in paroxysms of violence which saw entire cities laid waste and their populations dispersed or enslaved. For this reason the tribes frequently had bitter hatred for the others.
These weaknesses — the lack of centralized political authority and the resultant animosity between the tribes — were relentlessly and systematically exploited by Caesar during his conquest of Gaul. Caesar used a system of incentives and punishments to ally with some tribes and intimidate others, ensuring that he was only ever fighting one opponent at a time. He carefully presented himself as a defender of Gallic interests, and his military actions as aimed only at hostile tribes who threatened the peace and stability of Gaul. Neighboring tribes often agreed with his assessment, viewing those he assailed as deadly foes who had all too often plagued them, rather than as fierce potential allies in the wars to come. Many even supplied Roman forces with grain or auxiliary troops, or even offered the use of their towns as permanent bases for legionaries.
Eventually, though, there could be no mistaking Caesar’s true motive: not pacification, but conquest. The Gauls realized that they were on the verge of becoming a conquered people without ever having fought a war in their defense.
In response they elected Vercingetorix of the Arverni to lead the unified Gallic resistance with the goal of expelling the Romans from Gaul. Although Vercingetorix was a leader of an exceptionally high caliber, banding together the disparate tribes as had never been done, and enforcing discipline and order on a people who never known either; and despite his innovative strategy of continual retreat before the superior legions, burning or destroying all food that they left behind them denying Caesar the set-piece battle he desired, Vercingetorix eventually erred. Harried by the Romans, he and his forces sheltered in the walled city of Alesia. Caesar entrapped them within a double ring of defensive fortifications: one to keep Vercingetorix and his army confined, the other as protection against the relief army that was sure to come, and the Romans waited.
In the subsequent Battle of Alesia, Caesar's legions won such a crushing victory that Gallic resistance to Roman rule was no longer possible. Vercingetorix rode into the Roman camp alone and silently fell at the feet of Caesar, laying down his arms in token of submission in what Plutarch described as “the most famous surrender in antiquity.” The rest of the tribes followed, and they were integrated as the province of Roman Gaul. The region was eventually organized into the Tres Galliae alongside the older Gallia Narbonensis.

Mongol Empire

While the Mongols imported Central Asian Muslims to serve as administrators in China, the Mongols also sent Han Chinese and Khitans from China to serve as administrators over the Muslim population in Bukhara in Central Asia, using foreigners to curtail the power of the local peoples of both lands.

British India

Some Indian historians, such as politician Shashi Tharoor, assert that the British Raj frequently used this tactic to consolidate their rule and prevent the emergence of the Indian independence movement, citing Lord Elphinstone who said that "Divide et impera was the old Roman maxim, and it should be ours." A Times Literary Supplement review by British historian Jon Wilson suggests that although this was broadly the case a more nuanced approach might be closer to the facts. On the other hand, Proponents of Hindutva, the ideology of the current and recent Indian governments over the years, stress strongly Hindu-Muslim conflict going back centuries before the arrival of the British.
The classic nationalist position was expressed by the Indian jurist and supporter of Indian reunification Markandey Katju, who wrote in the Pakistani paper The Nation in 2013:
Historian John Keay takes a contrary position regarding British policy, writing:
General S.K. Sinha, former Vice-Chief of Army Staff, writes that contrary to what the notion of divide and rule would predict, the British Indian Army was effectively integrated:

Ottoman Empire

The Ottoman Empire often used a divide-and-rule strategy, pitting Armenians and Kurds against each other.

Europe

  • Athenian historian Thucydides in his book History of the Peloponnesian War claimed that Alcibiades recommended to Persian statesman Tissaphernes, to weaken both Athens and Sparta for his own Persian's benefit. Alcibiades, suggested to Tissaphernes that 'The cheapest plan was to let the Hellenes wear each other out, at a small share of the expense and without risk to himself.
  • Tacitus in Germania. chapter 33 writes "May the tribes, I pray, ever retain if not love for us, at least hatred for each other; for while the destinies of empire hurry us on, fortune can give no greater boon than discord among our foes."
  • In Revolutions of 1848, the governments which were being revolted against used this tactic to counter the rebels.
  • The colonial authorities in British Cyprus often stirred up the Turkish minority in order to neutralize agitation from the Greek majority. This policy intentionally cultivated further animosity between the already divided Greek majority and the Turkish minority in the island that remains divided to this day after an invasion by Turkey to establish the state of North Cyprus.
  • The partition of Ireland in 1921 has been claimed as an intentional implementation of this strategy by David Lloyd George, although the religious divisions in Ireland were notorious and of long standing. The Stanford historian Priya Satia claims that the partition of Ireland was in ways a patch-test for the partition of India in 1947.

    Colonialism

According to Richard Morrock, four tactics of divide and rule practiced by Western colonialists are:
  1. The manufacture of differences within the targeted population;
  2. The amplification of existing differences;
  3. The use of these differences for the benefit of the colonial empire; and
  4. The carry over of these differences into the post-colonial period.

United States

Some analysts assert that the United States is practicing the strategy in the 21st-century Middle East through their supposed escalation of the Sunni–Shia conflict. British journalist Nafeez Ahmed cited a 2008 RAND Corporation study for the U.S Armed Forces which recommended "divide and rule" as a possible strategy against the Muslim world in "the Long War".
