Nations are odd things. They are difficult to found and internally fractious, but resist splitting up again when irreconcilable differences happen. Moreover, international “clubs” – like the United Nations – are loathe to accept new nations, unless those nations navigate the wholly articial, Twister-like rules which those clubs set. Conversely, said clubs steadfastly refuse to accept any new nation declaring its existance, whether they have effective control and administration over their territory or not.
And, this is especially true when the state in question has absolutely no collective identity, but was artificially constructed by former European colonial masters who drew lines on a map in a smoking room in some European capital, ignoring what people lived where, caring solely for natural terrain features like rivers, lakes and mountains that required little effort to delineate, because those doing the drawing had a croquet match to attend at the lawn party outside.
The question isn’t whether Yemen will split into two countries again — it’s whether the international community will finally acknowledge what’s already happened on the ground. The entity we call “Yemen” exists primarily on maps and in UN resolutions, while the actual territory operates as separate political systems with different governments, currencies, and security forces. The reunification experiment that began in 1990 is effectively over. What remains for the “international community” is deciding how to make it official without looking like complete morons.
And it isn’t as though precedents do not exist for this sort of thing: The most successful modern national partition remains Czechoslovakia’s “Velvet Divorce” in 1993. Unlike Yugoslavia’s violent disintegration, Czech and Slovak leaders negotiated a peaceful split despite polls showing most citizens preferred staying united. The separation was orderly: assets divided, treaties apportioned, borders established without dispute. Both successor states joined NATO and the EU, maintaining close economic ties and visa-free travel. The key difference? Political leaders committed to negotiated settlement rather than violence, no external powers had strong interests in preventing partition, and both populations were relatively homogeneous within their territories. It remains the gold standard for how national separations should work — and how rarely they actually do.
Understanding why requires looking back at how these “two Yemens” came to exist in the first place, and why their marriage was probably doomed from the start.
The Original Split
Modern North Yemen emerged from the collapse of the Ottoman Empire, becoming an independent kingdom in 1918 under Imam Yahya. It remained a conservative, tribally-organized monarchy until a 1962 military coup sparked an eight-year civil war that eventually established the Yemen Arab Republic — backed by Egypt and the Soviet Union against Saudi-supported royalists. The north was predominantly Zaydi Shia in religious orientation, though more moderate than Iranian Twelver Shiism, with a strong tribal structure and conservative social organization.

South Yemen followed a completely different trajectory. After the British withdrawal from Aden in 1967, Marxist revolutionaries established the People’s Democratic Republic of Yemen — the only officially Marxist state in the Arab world. It was militantly secular, Soviet-aligned, and attempted rapid socialist transformation. The South’s population was more Sunni, more urbanized – centered around the port city of Aden – and ideologically committed to state-directed modernization. The two countries even fought a brief war in 1979.
These weren’t minor cultural differences. They represented fundamentally incompatible visions of governance, society, and Yemen’s place in the world.
The Unlikely Marriage
Reunification in 1990 was driven more by desperation than genuine reconciliation. The Soviet Union was collapsing, cutting off South Yemen’s economic lifeline. North Yemen’s economy was struggling. Both governments faced internal dissent and saw unification as a solution to their separate crises. President Ali Abdullah Saleh from the north and Ali Salim al-Beidh from the south negotiated a merger that papered over fundamental incompatibilities with promises of power-sharing and federal governance.
It lasted exactly four years before armed conflict erupted. The 1994 civil war saw northern forces, backed by Saudi Arabia and conservative tribal militias, defeat southern separatists decisively. What followed wasn’t genuine reunification but northern domination. Saleh’s government systematically marginalized southern politicians, appropriated southern oil revenues, and installed northern military commanders in southern territories. Resentment festered for two decades.

The Breaking Point
The “Arab Spring” reached Yemen in 2011, forcing Saleh from power but leaving underlying tensions unresolved. The Houthi movement — a Zaydi revivalist group from northern Yemen with Iranian backing — capitalized on the chaos. By 2014, they had seized the capital of Sanaa. When they pushed south toward Aden in 2015, Saudi Arabia launched a military intervention that continues today.
The conflict crystallized existing divisions. The Houthis control most of the north, operating what is effectively a separate state with its own governance, military, and foreign policy — as demonstrated by their attacks on Red Sea shipping in solidarity with Hamas. The Southern Transitional Council (STC), formed in 2017, controls much of the south including Aden, with UAE backing. They issue their own currency, operate separate security forces, and openly advocate for southern independence.
The internationally recognized government, meanwhile, barely controls anything and operates primarily from Saudi Arabia. This is a government in name only.
The October 2000 bombing of the destroyer USS Cole in Aden harbor — killing 17 American sailors — illustrated Yemen’s role as a base for transnational extremism long before the current crisis. Al-Qaeda in the Arabian Peninsula (AQAP) thrived in the ungoverned spaces created by weak central authority and competing factions. The current fragmentation has only worsened this problem, with AQAP and ISIS affiliates operating in territories neither Houthis nor STC fully control.
Why This Matters Beyond Yemen
The Houthi campaign against Red Sea shipping has demonstrated that a Yemeni faction can significantly disrupt global commerce even without international recognition. Their anti-ship and ballistic missiles, as well as “kamaikaze” drones, supplied by the Islamic of Iran, have forced naval deployments by the United States and European powers. A formally partitioned Yemen wouldn’t change these capabilities — it would simply acknowledge political reality.

More intriguingly, international recognition of a southern Yemeni state could establish precedent for other de facto separations. Somaliland, which declared independence from Somalia in 1991 and has maintained stable governance for over three decades, has long sought international recognition. If the international community accepts Yemeni partition based on historical precedent (the pre-1990 states) and effective governance, Somaliland’s case becomes significantly stronger, creating a range of possible fallout scenarios. Both represent functional states with historical legitimacy denied recognition due to international community inertia and fear of encouraging separatism.
The Path Forward
The question facing policymakers isn’t whether Yemen should split — it already has. The question is whether maintaining the fiction of Yemeni “national unity” serves any useful purpose, or whether acknowledging reality might actually enable better governance, clearer accountability, and more effective international engagement with whoever actually controls Yemeni territory.
Saudi Arabia and the UAE already deal with separate Yemeni entities. The Houthis negotiate independently with international actors. The Southern Transitional Council administers its territory with minimal reference to the “official” government. At what point does pretending these are temporary arrangements become more destabilizing than simply accepting the divorce?
Yemen’s reunification was an experiment that failed. Acknowledging that failure might be the first step toward actually addressing Yemen’s crises rather than pretending a unified government will somehow reassert control over territories it never effectively governed.
