Montesquieu's views on the separation of powers
Montesquieu is regarded as one of the most important intellectual influences on the writing of the US Constitution, particularly in his views on the separation of powers. Montesquieu, whose full name was Charles Louis de Secondat, Baron de La Brède et de Montesquieu, was a French philosopher in the early 1800s.
Montesquieu is known for his work on categorising regime types into monarchies, republics, and despotic governments. He believed that different laws, constitutions, and political systems were suited to different contexts, and that the key to understanding different laws and social systems is to recognise that they should be adapted to a variety of factors, including the people, the nature and principle of the government, the climate, the quality of the soil, the situation and extent of the country, the principal occupation of the natives, the degree of liberty the constitution will bear, the religion of the inhabitants, their inclinations, riches, numbers, commerce, manners, and customs.
In his work, Montesquieu emphasised the importance of preventing government corruption, which he believed was probable if a system of government did not include a balance of powers. He argued that in a democracy, corruption of the government sets in when the people attempt to govern directly, and try "to debate for the senate, to execute for the magistrate, and to decide for the judges". To prevent this, Montesquieu conceived the idea of separating government authority into three branches: the executive, legislative, and judicial. This perspective significantly influenced the authors of the US Constitution in establishing laws and division of duties, as well as in the inclusion of provisions to preserve individual liberties.
While Montesquieu advocated for the separation of powers, he did not argue for a complete separation. Instead, he recommended that no person or group holding the totality of one power should hold another power in its entirety. He praised the British system, which had a hybrid executive consisting of the King, the cabinet, and certain standing committees. Montesquieu recommended a true unitary executive, which was reflected in the US Constitution. He also suggested that the executive should have a veto on new laws, which was included in the Constitution. Additionally, he proposed that beyond the veto, the president should not share a significant portion of legislative power, and that the legislative branch should be composed of many persons, while the executive branch should be led by just one person.

Montesquieu's influence on the US Constitution's division of duties
Charles-Louis de Secondat, Baron de La Brède et de Montesquieu, was a prominent French philosopher in the early 1800s. Montesquieu is regarded as one of the most significant influences on the writing of The Federalist Papers, which are fundamental to originalist interpretations of the US Constitution. Montesquieu's ideas on government provided a framework for the separation of powers, which became integral to the US Constitution's division of duties.
Montesquieu's views on government corruption and the probability of its occurrence in the absence of a balance of powers led him to conceive of the separation of governmental authority into three branches: the executive, legislative, and judicial. This concept significantly influenced the authors of the Constitution in establishing laws and dividing duties, as well as in including provisions to protect individual liberties. While Montesquieu did not advocate for a complete separation of powers, he emphasised that no individual or group holding the entirety of one power should hold absolute power in any other area.
In his work, Montesquieu praised the British system, which had a blurred separation of powers, and even recommended that the executive have a veto on new laws. The Federalists, however, pointed out that America was not creating a unitary republic like Britain, but rather a federation of states—a solution Montesquieu proposed for extending republican government over a large territory. Montesquieu's influence can also be seen in the US Constitution's method of impeachment and removal of federal officers, as well as the composition of the legislative and executive branches.
Montesquieu's ideas on the separation of powers were not entirely original, as he drew from contemporary English writers and John Locke. Nonetheless, he contributed new ideas and emphasised certain elements, particularly regarding the judiciary, that had not been given much attention previously. His work on categorising regime types into monarchies, republics, and despotic governments also had a lasting impact, with the notion that non-Western governments tend to be authoritarian still persisting today.

Montesquieu's ideas on preventing government corruption
Montesquieu is regarded as a source of some of the most important ideas in law and one of the most important intellectual influences that shaped the writing of The Federalist Papers, which serves as a touchstone for originalist interpretations of the US Constitution. Montesquieu's ideas on preventing government corruption are detailed below:
Separation of Powers
Montesquieu is most associated with the doctrine of the separation of powers. He argued that government corruption was probable if a system of government did not include a balance of powers. He conceived of separating government authority into three branches: executive, legislative, and judicial. Montesquieu did not advocate for a complete separation of powers, but rather for the “non-confusion” of powers, meaning that no person or group holding the totality of one power should hold another power concurrently. This perspective significantly influenced the authors of the US Constitution in establishing laws and divisions of duties, as well as in the inclusion of provisions to preserve individual liberties.
Checks and Balances
Montesquieu's idea of the separation of powers is closely tied to the concept of checks and balances. He believed that different bodies should exercise legislative, executive, and judicial powers, and that these bodies should be bound by the rule of law. This theory influenced the US Constitution's system of checks and balances, where the different branches of government have the ability to limit and balance the power of the other branches.
Independence of Judgment
While Montesquieu advocated for the separation of powers, he believed that independence of judgment was more fundamental than a strict division of powers. He recommended that the executive have a veto over new legislation, which was included in the US Constitution. He also suggested that beyond this veto power, the president should not share a significant portion of legislative power, reflecting his view that the executive branch should be led by a single person while the legislative branch should be composed of many persons.
Federalist System
Montesquieu argued that a republican form of government would break down if it extended over a large territory. To address this, he proposed a "confederate republic" or a federation of states, where a central authority has some power but most authority is retained at the state level. This idea influenced the US Constitution, which established a federalist system with a division of powers between the federal and state governments.
Political Virtue in Democracy
Montesquieu recognized the potential for corruption in democracy, where the people attempt to govern directly and interfere with the functions of the senate, magistrates, and judges. He believed that the principle of democracy is political virtue, which he defined as "the love of the laws and of our country." A functioning democracy, according to Montesquieu, requires a constant preference for the public interest over private interest and a self-renunciation that limits ambition to serving one's country. These ideas emphasize the importance of civic duty and the need for informed and engaged citizens to prevent government corruption.

Montesquieu's concept of doux commerce
While Baron de Montesquieu was not directly involved in the development of the US Constitution, his views on government provided the framework for the separation of powers. Montesquieu's concept of doux commerce (literally "sweet commerce") is a theory from the Age of Enlightenment stating that commerce tends to make people more civilized, reducing their propensity for violence or irrational behaviour. This theory, also known as commercial republicanism, suggests that the expansion of trade and commerce will reduce violence, even open warfare. Montesquieu wrote, "wherever the ways of man are gentle, there is commerce; and wherever there is commerce, there the ways of men are gentle" and "The natural effect of commerce is to lead to peace".
Montesquieu's ideas on doux commerce were influenced by his observations of the English Constitution and his belief that democracy was only suitable for small societies. He argued that in a democracy, corruption occurs when people attempt to govern directly, such as by "trying to debate for the senate, execute for the magistrate, and decide for the judges". To prevent this, Montesquieu proposed that some form of separation of powers is necessary, dividing government authority into three branches: executive, legislative, and judicial. This perspective significantly influenced the authors of the US Constitution in establishing laws and divisions of duties, as well as in including provisions to protect individual liberties.
The concept of doux commerce gained popularity in the 17th century and was endorsed by Enlightenment thinkers like Voltaire, Smith, Hume, and Immanuel Kant. Montesquieu is often credited with spreading the idea through his influential work, "Spirit of Law" (1748), and the theory is sometimes referred to as "Montesquieu's doux commerce". However, it's important to note that Montesquieu himself did not use the term "doux commerce".
While proponents of doux commerce argued that trade and commerce would lead to more peaceful societies, critics like Edmund Burke challenged this notion. Burke suggested that it is not commerce that civilizes humans, but culture that enables people to engage in commerce. Additionally, later scholars criticized the theory for overlooking the negative aspects of certain "gentle" trade practices, such as the slave trade and colonial exploitation.
In conclusion, Montesquieu's concept of doux commerce played a significant role in shaping his views on the separation of powers, which in turn influenced the US Constitution. The idea that commerce civilizes people and reduces violence was an important aspect of his political philosophy, contributing to his belief in the necessity of a balanced system of government with separate branches to prevent corruption and promote peace.

Montesquieu's views on the suitability of different laws and constitutions to different contexts
Montesquieu is regarded as a source of some of the most important ideas in law and one of the most important intellectual influences that shaped the writing of The Federalist Papers, which serves as a touchstone for originalist interpretations of the U.S. Constitution. Montesquieu's views on the suitability of different laws and constitutions to different contexts are informed by his belief that different laws and social systems should be adapted to a variety of factors. These factors include the people for whom the laws are framed, the nature and principles of the government, the climate of the country, the quality of its soil, its situation and extent, the principal occupation of the natives, the degree of liberty the constitution will bear, the religion of the inhabitants, their inclinations, riches, numbers, commerce, manners, and customs.
Montesquieu's work, "Spirit of the Laws", systematically compares different regimes, including European, historical, and worldwide regimes. He categorised regime types into monarchies, republics, and despotic governments, associating the latter with non-Western governments. Montesquieu's views on the suitability of different laws and constitutions to different contexts are also reflected in his concept of doux commerce, which theorises that commerce civilises people and nations and leads to peace and harmony. This concept continues to influence debates about whether free trade leads to democracy and peace.
Montesquieu's ideas on the separation of powers are also relevant to his views on the suitability of different laws and constitutions. He argued that government corruption was likely if a system of government did not include a balance of powers. He proposed separating governmental authority into three major branches: executive, legislative, and judicial. This perspective influenced the authors of the U.S. Constitution in establishing laws, dividing duties, and including provisions to preserve individual liberties. Montesquieu did not advocate for a complete separation of powers but rather for a system where no person or group holding one power should hold another entirely. He praised the British system, which had a blurred power dynamic, and recommended that the executive have a veto on new laws, which was incorporated into the U.S. Constitution.
Additionally, Montesquieu's views on the limitations of republican governments influenced the structure of the U.S. federal system. He argued that a republican government would break down if it extended over a large territory and proposed a "confederate republic" solution, where a union of states grants some power to a central authority while retaining most authority at the state level. This idea aligned with the Federalist perspective that they were creating a federation of states rather than a unitary republic.
