Which European countries do not have their own army?

Envision the intricate map of Europe, its nations intertwined by centuries of politics, peace treaties, and changing borders. Many travelers imagine Europe as a patchwork of countries, each fielding its own military—flags over barracks, soldiers in distinctive uniforms, parades on public holidays. But a lesser-known fact surprises many visitors: a handful of European states manage without a standing army at all. Their solutions are as unique as their histories, revealing a tapestry of sovereignty, security partnerships, and neutral traditions that challenge our assumptions about national defense.

What you should know about European countries without an army

Ask around in a European capital or sleepy rural village, and most residents won’t hesitate to name the nearest military base. Yet a small but fascinating group of countries—principally Andorra, Liechtenstein, Monaco, San Marino, and the Vatican City—do not field their own armed forces. Each has a distinct reason, shaped by geography, treaties, and identity. Some, like Liechtenstein, abolished their armies long ago after bitter experiences, while others have relied on neighboring states or international agreements for generations. For those planning a visit, these stories add a unique flavor to the local history and street-level life.

Travelers passing through, say, the borders of San Marino or Monaco generally won’t notice tanks, checkpoints, or platoons marching past downtown squares. Instead, security here takes subtler forms. Police and small specialized guard units replace the visible military presence most Europeans take for granted. In real travel conditions, this makes border crossings unexpectedly swift—sometimes marked only by a discreet sign and a slightly different architectural style.

Field reporting suggests that locals in these microstates often carry a heightened sense of diplomatic and cultural identity, compensating for the absence of visible military with a fierce pride in heritage. During a springtime visit to Monaco, one might overhear café conversations speculating on France’s protective commitment, or in Andorra, see schoolchildren learning about their nation’s special status wedged in the Pyrenees. Yet, there’s little anxiety; the framework seems normalized.

Therefore, the key takeaway is that these countries’ lack of an army is not just a bureaucratic footnote—it’s woven through their streets, policies, and social consciousness, offering travelers a fresh lens on what it means to be both secure and sovereign in the heart of Europe.

Who protects countries without armies? A closer look at their security partners

For most European states, sovereignty and safety are fundamentally connected to a standing army. So how do those without one stay secure in unpredictable times? Their defense relies on neighborly agreements, historic treaties, and at times, symbolic forces. Liechtenstein, for example, has a special understanding with Switzerland. The Swiss take primary responsibility for its defense—a commitment visible not through troops on the ground, but through discreet diplomatic channels and shared crisis procedures.

Monaco’s situation is equally distinctive. Hemmed in by the glamorous French Riviera, its defense is the responsibility of France. Few travelers realize, while walking through the bustling Port Hercule, that the nearest French gendarmerie can be on site within minutes if necessary. Meanwhile, the Vatican City leans on the Italian military under the 1929 Lateran Treaty, with only the ceremonial Swiss Guard on display for tourists snapping photos near Saint Peter’s Square.

Andorra, nestled between France and Spain, maintains its own police but relies on both neighbors for military protection. During an autumn hike through Andorran valleys, hikers sometimes encounter French or Spanish border patrols—but rarely, if ever, soldiers in camouflage. San Marino, the world’s oldest republic, entrusts its security to Italy and boasts only a handful of ceremonial and policing units. The real lifelines are the extensive political and legal agreements with larger states—proof that size matters less than strong, steady partners.

According to recent research, the collective population of European countries without an army is roughly equal to that of a single mid-sized European city, making their security solutions niche but effective.

In practice, these well-honed relationships allow each country to sidestep the costs and complexities of running an army, while relying on broader regional security. Success depends on diplomacy and the depth of inter-state trust.

The special case of microstates: Why they choose not to have armies

Europe’s microstates are worlds unto themselves. Tiny by area and population, their economies rely heavily on tourism, finance, or unique exports, not military might. These countries have historically found armies not just unnecessary, but a liability. For Liechtenstein, the abolition of its army in 1868 followed a disastrous deployment and was greeted with relief by its citizens. In Vatican City, the sovereign’s interests are strictly spiritual and diplomatic rather than territorial.

During routine travel, visitors are often amused to discover the level of pomp—rather than actual force—represented by the guards in San Marino or the Vatican. In Monaco, the spectacle centers around the “Carabiniers du Prince” rather than on genuine military readiness. As frequent travelers notice, the general atmosphere is peaceful, and the sense of security feels tied to international standing rather than deterrence.

The microstate model offers advantages and risks. On the one hand, the absence of heavy military obligations allows for more social spending, minimal defense budgets, and a distinct “open border” feel—features that appeal to tourists and citizens alike. However, reliance on foreign powers for protection, while stable in today’s Europe, requires absolute confidence in long-term alliances.

Military strategist Dr. Eva Schmidt observes: “For microstates in Europe, the real defense is not in troops or tanks, but in robust diplomacy and a global reputation for neutrality or partnership.”

To sum up, microstates’ decision not to maintain armies is an enduring choice shaped by practicality and a deep-seated belief in peaceful coexistence—with special benefits and subtle, ever-present vulnerabilities.

How to choose: Visiting countries with and without armies

For the curious traveler, the military status of a destination may not be an obvious factor in planning, but it quietly shapes the travel experience. European countries with their own military often display overt national pride through parades and monuments—a different flavor than the understated ambiance of, for example, Liechtenstein. The contrasts extend to holiday events, border crossings, and the visible presence of authorities. Those fascinated by history and the art of neutrality may naturally gravitate to microstates where old treaties and ceremonial guards have replaced barracks and tank parks.

The choice between “army” and “no army” countries isn’t merely academic. In practice, crossing from a heavily militarized border, such as those found in Eastern Europe, to the almost invisible frontiers of Monaco or San Marino, travelers often comment on the lighter, more open atmosphere. If you’re someone deeply interested in the politics of neutrality or the subtler cues of international cooperation, these destinations offer much to observe. Meanwhile, students of military history may still find plenty to discover in the museums and archives—minus the martial regalia on the streets.

One practical travel tip: when visiting microstates, check ahead for public ceremonies. National days often feature distinctive rituals unrelated to military pageantry, such as religious processions in Vatican City or firefighters’ parades in Monaco. These make for unforgettable photos and anecdotes—opportunities travelers rushing on to larger neighbors may easily miss. For some, the absence of an army actually results in a friendlier, less guarded interaction with locals.

The key point is that the defense arrangements of these countries subtly influence travelers’ perceptions and experiences, offering a less militarized, more open European journey.

Benefits vs drawbacks: Is no army a good thing for European countries?

The question of whether to forgo a standing army brings real trade-offs. On the positive side, countries without armed forces save billions in military expenditure, funds that can then be invested in education, health care, and infrastructure. This alternative approach has arguably boosted quality of life in tiny states—one reason they often rank highly in European well-being statistics. Microstates also avoid becoming entangled in regional conflicts or alliances that might otherwise compromise their independence.

Yet, there are costs. Complete dependence on neighboring powers can raise risks if those powers’ priorities change. In periods of global upheaval, the inability to defend their own territory—even symbolically—could become an existential weakness. There’s also the question of international standing. Some argue that not participating in collective defense mechanisms, like NATO, may diminish these countries’ influence in broader European security discussions.

Pragmatically, most countries without armies supplement police with highly trained units for internal security and civil emergencies. For instance, San Marino’s “Guardia di Rocca” combines policing and light ceremonial duties. Monaco leans on cross-border collaboration with France for everything from counter-terrorism to major event security. Back in 2023, a group of tourists in Andorra recounted noticing French police vehicles parked at the base of a popular hiking trail—an example of this “behind-the-scenes” protection in action.

A case study of San Marino found that public trust in security remained consistently high, despite the absence of a national military—suggesting that effective policing and visible international partnerships can maintain confidence.

In the end, the absence of an army is both an opportunity for social investment and an ongoing test of diplomatic agility, with benefits and drawbacks intricately balanced.

When it makes sense to rely on treaties: Lessons from the microstates

For the smallest states in Europe, formal neutrality or reliance on defense treaties isn’t just a relic of the past—it remains a rational choice in the fast-changing twenty-first century. Their landlocked or enclave status means the cost and logistics of building a military are insurmountable. Strategic alignment with neighbors is reinforced not just by history, but by day-to-day cooperation, from police training to disaster response. The strength of these arrangements is most visible during times of European solidarity or crisis.

Field interviews in Liechtenstein reveal residents’ near-universal support for the Swiss security umbrella. After all, there’s little appetite for conscription or military spending when schools and healthcare benefit instead. In Vatican City, the Swiss Guard provides ceremonial protection, but visitors quickly realize that any serious threat would be handled by Italy. And around San Marino’s fortresses, locals speak warmly of their Italian lifeline—reminding new arrivals that their calm existence has survived world wars and shifting borders.

However, the durability of these treaties relies on a stable web of international law and mutual interest. The lessons here are poignant: in a world where new threats emerge rapidly, microstates must remain agile, tending to their alliances and public perception with the same care as larger countries devote to military drills. Sometimes, the absence of an army can provide greater security—precisely because it signals no threat and a willingness to collaborate.

The essential insight is that for nations with the right mix of geography, alliances, and reputation, not having an army is a calculated choice that still delivers safety and peace.

Table: Traveler experience – Microstates without armies vs neighboring countries

In practice, travelers remark on the less “official” border experience in spots like Andorra or Liechtenstein, with an almost seamless cultural transition into neighboring France, Spain, or Switzerland.

How-to: Experience a borderless microstate efficiently

1. Research entry requirements—often none for EU/Schengen travelers.
2. Plan to visit during local national celebrations for unique experiences.
3. Observe local police or ceremonial guards as a reflection of the nation’s approach to security.
4. Check for museums or historical monuments that explain the absence of a military.

The real charm often lies in absorbing the atmosphere rather than ticking off “military sights.”

Exploring beyond the army-free states: What travelers often overlook

Many visitors to Europe’s army-free microstates treat them as day-trip curiosities rather than destinations with layered, living cultures. Yet, it pays to slow down. Spend a night in Liechtenstein’s capital and you might catch an impromptu alpenhorn concert in the square—an echo of peace, not martial glory. Or wander San Marino’s medieval alleys at dusk, noticing aerial views long defended only by stone walls and stalwart alliances, not conscripts or guns.

One field story stands out: while hiking above Andorra La Vella, a group of backpackers marveled at the unbroken expanse of green stretching into France and Spain. Not a checkpoint in sight—just open nature and an odd sense of security. Fascination with lurking geopolitical risks gives way, for a few hours, to a sense of shared stewardship. That’s the subtle draw of these microstates for the well-informed traveler.

Travelers sometimes overlook deeper links between these countries and their region. Take winter in northern Italy—many pass through Milan en route to ski resorts but overlook the option to explore Macugnaga, a quaint Alpine community. Its atmosphere mirrors the peace found in neighboring microstates, an idea echoed by mountain guides familiar with both the Italian Alps and the Pyrenees. For those curious, learning about places like Macugnaga can add authentic depth to an itinerary—highlighting broader themes of history and resilience in the region. If intrigued by the interplay of heritage and safety, travelers might enjoy reading about a day on Italy’s Monterosa slopes for a contrasting adventure.

Ultimately, exploring Europe’s nations without armies is about more than a checklist; it’s an invitation to see sovereignty, safety, and cultural pride through new eyes.

If you’re in search of seasonal contrasts, try arriving for late summer festivals. On August 26th, Liechtenstein celebrates its National Day with fireworks and family gatherings, rather than shows of force—a tradition appreciated by those aiming to experience authentic local life. For more on how holidays are marked in this unique corner of Europe, you might find an insider guide to the festivities especially revealing.

During winter, Bristol’s famous Christmas markets create a different, military-free festive energy—contrasting sharply with parade-heavy celebrations elsewhere. Curious travelers can discover what sets this scene apart by checking out firsthand Bristol holiday experiences.

On February 7th, in another part of Europe, the absence of overt military celebration allows for more civic spirit and relaxed traditions—a reminder that not all national pride wears a uniform. If you’re interested in seasonal perspectives, see how locals spend winter days by reading about offbeat February traditions in Europe’s peaceful enclaves.

When planning wide-ranging European itineraries, some adventurers use platforms that aggregate unbiased insights and regional perspectives—a process similar to what civil society travel platforms provide. These resources allow for a deeper appreciation of less militarized spaces and community-based experiences.
