Gunboat diplomacy refers to the use of military force or the display of naval power to exert political influence and shape foreign policies. The term originates from the 19th century, when Western powers, particularly European nations and the United States, employed their superior naval capabilities to coerce smaller or weaker nations into granting concessions. This tactic was often used during the colonial era to secure favourable trade agreements or territorial gains. While some consider gunboat diplomacy a relic of the past, it has persisted in various forms into the 21st century, with modern governments leveraging their naval might to pursue diplomatic objectives and project power on the world stage.

Gunboat diplomacy is distinct from defence diplomacy, which is the peaceful application of defence resources to achieve positive outcomes in the development of bilateral and multilateral relationships
Gunboat diplomacy refers to the use or threat of military force to achieve foreign policy objectives. It involves highly visible displays of naval power, implying a direct threat of warfare should terms not be agreed upon by the superior force. The term "gunboat diplomacy" emerged during the nineteenth-century period of imperialism when Western powers, including Europe and the United States, intimidated less powerful entities into granting concessions through demonstrations of their superior military capabilities.
Gunboat diplomacy is distinct from defence diplomacy, which is a peaceful approach that does not involve military operations. Defence diplomacy aims to achieve positive outcomes in bilateral and multilateral relationships by utilising defence resources in a non-confrontational manner. While gunboat diplomacy relies on displays of force, defence diplomacy focuses on activities such as international personnel exchanges, ship and aircraft visits, high-level engagements, training, security-sector reform, and bilateral talks.
An example of gunboat diplomacy is the Don Pacifico affair in 1850, where the British Foreign Secretary, Lord Palmerston, dispatched a squadron of the Royal Navy to intimidate a weaker nation into submission. On the other hand, defence diplomacy may involve sending ships for friendly visits to foster goodwill and improve relationships without any implied threat.
Another key difference is the nature of the resources employed. Gunboat diplomacy primarily utilises military assets, such as warships or aircraft carriers, as a means of coercion. In contrast, defence diplomacy draws on a broader range of defence resources, including personnel, training, and other non-military assets, to achieve its objectives through cooperation and mutual understanding.
While gunboat diplomacy may lead to the establishment of new trade relationships, colonial outposts, and the expansion of empires, defence diplomacy seeks to achieve similar outcomes through peaceful means. Defence diplomacy recognises the value of positive relationships and aims to foster cooperation and collaboration between nations without resorting to threats or displays of military power.

Military diplomacy is a subset of defence diplomacy, referring to the role of military attachés and their associated activity
Gunboat diplomacy refers to the pursuit of foreign policy objectives through the use or threat of military force, particularly naval power. This term originated in the nineteenth century when Western powers would intimidate less powerful entities into granting concessions by demonstrating their superior military capabilities.
Military diplomacy, a subset of defence diplomacy, is distinct from gunboat diplomacy in that it involves the non-violent actions of armed forces to influence foreign governments. It refers specifically to the role of military attachés and their associated activities. Military diplomacy includes dialogue, negotiations over conflict termination or security issues, defence and security cooperation, and demonstrations of force.
While defence diplomacy also seeks to achieve positive outcomes in the development of bilateral and multilateral relationships, it does not include military operations. Instead, it encompasses activities such as international personnel exchanges, ship and aircraft visits, high-level engagement, training, security-sector reform, and bilateral military talks.
The United Kingdom, for example, identifies defence diplomacy as one of the military's eight defence missions, aiming to dispel hostility, build trust, and assist in the development of democratically accountable armed forces to contribute to conflict prevention and resolution.
Military diplomacy is often overlooked, but it remains a critical tool in the pursuit of national interests and the implementation of foreign policy. It plays a vital role in shaping security policies and maintaining stable international relations.

The concept of gunboat diplomacy emerged during the late nineteenth-century period of imperialism, when Western powers competed to establish colonial trading empires
The concept of gunboat diplomacy emerged during the late nineteenth-century period of imperialism. During this time, Western powers from Europe and the United States competed to establish colonial trading empires in Asia, Africa, and the Middle East. Gunboat diplomacy refers to the use or threat of military force, typically naval power, to pursue foreign policy objectives and intimidate other entities into granting concessions. The term "gunboat" implies a projection of naval power, with warships appearing off the coast of a target country, demonstrating superior military capabilities.
A notable example of early gunboat diplomacy is the case of Commodore Matthew Perry and his fleet of "Black Ships" in 1853. Perry sailed four solid black warships into Japan's Tokyo Bay, and without a navy of its own, Japan quickly agreed to open its ports to trade with the West after over two centuries of isolation. This display of naval might set a precedent for using gunboat diplomacy to establish colonial outposts and expand empires.
Another example of gunboat diplomacy is the Roosevelt Corollary, also known as "Big Stick" diplomacy, which was employed by U.S. President Theodore Roosevelt in the early 20th century. This policy was used to justify U.S. military occupations of Cuba in 1906, Nicaragua in 1912, and Veracruz, Mexico in 1914, during the Mexican Revolution. As the United States grew into a military power, Roosevelt's approach was later replaced by "dollar diplomacy," which aimed to substitute economic incentives for direct military threats.
Gunboat diplomacy is considered a form of hegemony, or the dominance of one country over others in political, economic, and military spheres. While the term originated in the naval power projections of the 19th century, it has evolved to include land-based equivalents, such as military mobilization and the massing of troops near international borders. Today, gunboat diplomacy continues to be employed, particularly by the United States, which maintains a global network of naval bases and frequently uses the presence of its navy to influence foreign governments.

Gunboat diplomacy is considered a form of hegemony, or the political, economic, and military predominance of one country over others
Gunboat diplomacy refers to the pursuit of foreign policy objectives through displays of naval power, implying a direct threat of warfare if demands are not met. This strategy was commonly employed by Western powers during the 19th-century period of imperialism to intimidate less powerful nations into granting concessions. As such, gunboat diplomacy is indeed considered a form of hegemony, entailing the political, economic, and military dominance of one country over others.
The term "hegemony" refers to the predominance of a single state over others, and gunboat diplomacy has been a tool used by hegemonic powers to exert their influence. During the late 19th and early 20th centuries, the practice was associated with the imperialist policies of European nations and the United States. A notable example is the Don Pacifico affair in 1850, where the British Foreign Secretary, Lord Palmerston, dispatched a squadron to blockade a Greek port, demonstrating Britain's naval might.
Gunboat diplomacy was particularly effective in establishing new trade relationships, colonial outposts, and expanding empires. Nations with superior naval power could coerce smaller countries into agreeing to their terms, often without resorting to actual warfare. This form of diplomacy allowed hegemonic powers to project their military strength and secure economic advantages.
The United States, as it emerged as a military power in the early 20th century, provides another example of gunboat diplomacy as a form of hegemony. President Theodore Roosevelt's "Big Stick" diplomacy was a prominent manifestation of this strategy. However, as private investment and economic influence grew, "dollar diplomacy" partially replaced the more explicit threats of military force.
In the post-Cold War era, gunboat diplomacy has evolved but remains prevalent. The overwhelming sea power, mobility, and flexibility of the United States Navy continue to shape global politics. For instance, during the Yugoslav wars of the 1990s, the Clinton administration used Tomahawk missiles and airborne surveillance aircraft as diplomatic tools, showcasing the enduring relevance of gunboat diplomacy in international relations.

Examples of gunboat diplomacy include the US Army's occupation of Veracruz in 1914 during the Mexican Revolution, and the US military occupations of Cuba in 1906 and Nicaragua in 1912
Gunboat diplomacy is a term that originated in the nineteenth century, referring to the use of naval power to intimidate less powerful nations into granting concessions. It is distinct from "defence diplomacy", which is a peaceful application of defence resources to achieve positive outcomes in the development of bilateral and multilateral relationships.
The US Army's occupation of Veracruz in 1914 during the Mexican Revolution is an example of gunboat diplomacy. On April 21, 1914, the US Marine landing party arrived in Veracruz, Mexico, to secure the area and protect American interests. The Mexicans, led by General Maas, attempted to halt the naval landing, but the message to pull back came too late. The US forces advanced through Veracruz, encountering heavy fire from Mexican riflemen. They occupied key areas, including the Plaza Constitución, and seized thousands of weapons, ammunition, and powder. The American flag was raised over their headquarters at the Terminal Hotel on April 27.
Another instance of gunboat diplomacy is the US military occupation of Cuba in 1906. Following the resignation of President Estrada Palma, a US-led provisional government was established to govern the island. From 1906 to 1909, the US military occupied Cuba to suppress an insurrection and maintain control. This intervention was justified by the Platt Amendment, which allowed the US to intervene militarily in Cuba to defend its interests.
Additionally, in 1912, the US sent Marines to Cuba to protect American property during an armed rebellion by Afro-Cubans in Oriente Province, known as the "race war." This intervention demonstrates how gunboat diplomacy was used to protect US economic and political interests in Cuba.
The US military occupation of Nicaragua in 1912 can also be considered an example of gunboat diplomacy. While details on this specific event are scarce, it is known that the US intervened in Nicaragua during this period, further asserting its influence in the region.
