Overview
Tanzania holds a rank-60 passport reaching 68 destinations without a prior visa. Its population is around 67.4 million, the constitutional capital is Dodoma (the economic centre is Dar es Salaam), and the currency is the Tanzanian shilling (TZS).
Tanzania has no citizenship-by-investment programme, and 🔴 does not permit dual citizenship.
📌 But Tanzania holds two nationality facts very few countries do.
✅ 1964 — two countries merged, and this time it held
The Yemen article records the only instance of two independent states voluntarily merging — 🔴 and tells what followed: civil war in 1994 and southern dissatisfaction persisting today.
📌 Tanzania is the second case, and the one that has held for sixty years.
The events, stated as facts:
- 📌 Tanganyika on the mainland became independent in 1961. Zanzibar — the offshore archipelago — became independent in 1963, with a revolution in early 1964.
- ✅ In April 1964 the two merged, later taking the name Tanzania from both.
🔴 But the structure of this union is highly unusual, and that is precisely why it survived:
- 📌 Zanzibar retains its own government, president, legislature and administration for non-union matters.
- 🔴 Tanganyika has NO separate government — the union government administers the mainland directly.
- 📌 This is an asymmetric federation: one side has its own state, the other does not.
🔴 For completeness: this structure has been a standing political debate in Tanzania for sixty years — over the extent of Zanzibar's autonomy and whether the mainland should have its own government. 🔴 Zanzibar has also seen internal political tension across several election cycles.
📌 The lesson beside Yemen: in Yemen, two states merged into a symmetric structure on paper and then fought a civil war. 📌 In Tanzania the structure is asymmetric and far less tidy — but it let one side keep its institutions, and the union survived.
🔴 For readers of this site: 📌 one very concrete consequence is that Zanzibar issues its own residence documentation, and mainlanders seeking long-term residence in Zanzibar must follow Zanzibar's rules. Within one country holding one passport, there are two residence regimes.
✅ Naturalising more than a hundred thousand refugees
📌 This is the second fact, and it belongs to this library's most important sequence.
I have recorded fifteen mechanisms producing people unable to prove nationality, and only two cases with a remedy: Iraq (the 2006 restoration law) and Kenya (the Shirika Plan, under implementation).
✅ Tanzania is the third, and the one that is COMPLETED.
The events, stated as facts:
- 🔴 From 1972, hundreds of thousands of Burundian refugees came to Tanzania and lived in settlements for decades. Their children and grandchildren were born in Tanzania.
- ✅ From around 2007 Tanzania opened a naturalisation programme for this group, and by the mid-2010s had granted Tanzanian citizenship to more than a hundred thousand people.
- 📌 UN agencies describe this as among the largest refugee naturalisation exercises ever conducted anywhere.
🔴 For completeness: the process saw periods of stalling and domestic debate over relocating those naturalised, and Tanzania's policy toward later refugee groups has been considerably tighter. 📌 But the figure of more than a hundred thousand people granted citizenship is real and completed.
📌 Why this deserves recording on a site about investment citizenship:
🔴 This whole site is written for people who already hold a nationality and want a second. The fifteen-article sequence on statelessness shows the far larger group has almost nobody serving it.
✅ Tanzania is evidence that the problem CAN be solved — not by an international convention or a donor fund, but by a state deciding to grant citizenship to people who had lived on its soil for thirty years.
📌 Swahili — building a nation through a language
📌 After independence Tanzania adopted Swahili as the national language and the medium of primary instruction — a deliberate decision.
🔴 The context: Tanzania has more than a hundred ethnic groups, none an overwhelming majority. 📌 Choosing Swahili — a coastal trading language, not the mother tongue of the largest group — meant no group was favoured over another.
✅ The widely documented result: Tanzania has markedly higher inter-ethnic cohesion than the regional norm, and researchers regularly cite this language policy among the reasons.
📌 Placed beside what this library has recorded: Myanmar uses an ethnic list in law to exclude; Rwanda recorded ethnicity on identity cards with catastrophic consequences; Bolivia lists 36 languages in order to recognise.
🔴 Tanzania chose a fourth way: listing nobody, and creating a shared foundation no group owns. 📌 It is a policy choice worth reflecting on, and it shows there are more than two ways to handle diversity.
Geography & economy
📌 Tanzania has Mount Kilimanjaro — Africa's highest peak, the Serengeti, the Ngorongoro Crater, and Lake Victoria alongside Lake Tanganyika, the world's second-deepest lake.
📌 Zanzibar's Stone Town is a UNESCO site and was a centre of the spice trade and Indian Ocean commerce for centuries. 🔴 Zanzibar was also a centre of the East African slave trade — a history discussed less than the Atlantic route.
Economy: tourism (among the largest foreign currency earners), agriculture (coffee, cashews, tea, spices), mining (gold, and 📌 tanzanite — a gemstone found in only one area in the world, at the foot of Kilimanjaro), and gas.
🔴 Disadvantages: power and transport infrastructure remain limited beyond main corridors; rising public debt; and 🔴 major infrastructure projects, including a regional oil pipeline, are contested on environmental and resettlement grounds.
As always: tax obligations here do not replace those in your country of residence.
Immigration routes & citizenship
Categories existing in law include work permits by class, residence tied to investment at prescribed thresholds, and residence through marriage. 📌 Zanzibar has its own rules — establish clearly where your documents are valid.
🔴 No dual citizenship. Those naturalising must renounce their prior nationality; Tanzanians acquiring another nationality lose Tanzanian citizenship. 📌 Permitting dual citizenship has been debated for years without adoption — check the current rules.
🔴 If anyone offers you "Tanzanian citizenship by investment", stop. No such programme exists.
Who should consider Tanzania
It may fit if: you work in tourism, agriculture, cashew processing, mining, gas or port logistics — 📌 Dar es Salaam serves several landlocked countries in the region.
Not a fit if: 🔴 you want an additional nationality while retaining Vietnamese; 🔴 you are offered "Tanzanian citizenship by investment"; or you are planning in Zanzibar without knowing it has separate rules.
The point to carry away: Tanzania offers two lessons running in opposite directions, both valuable.
📌 One — two countries can merge and hold, if the structure lets one side keep its institutions. Yemen merged symmetrically and broke; Tanzania merged asymmetrically and has lasted sixty years.
✅ Two — and this is what I want to stress: of the fifteen statelessness cases in this library, Tanzania is the only country to have COMPLETED the granting of citizenship to more than a hundred thousand people who previously had none. 🔴 No convention required them to do it. They simply decided to.
