Zanzibar Archipelago in the context of "Zanzibar"

Tanzania, officially the United Republic of Tanzania, is a country in East Africa within the African Great Lakes region. It is bordered by Uganda to the northwest; Kenya to the northeast; the Indian Ocean to the east; Mozambique and Malawi to the south; Zambia to the southwest; and Rwanda, Burundi, and the Democratic Republic of the Congo to the west. According to a 2024 estimate, Tanzania has a population of around 67.5 million, making it the most populous country located entirely south of the equator.

Many important hominid fossils have been found in Tanzania. In the Stone and Bronze Age, prehistoric migrations into Tanzania included Southern Cushitic speakers similar to modern day Iraqw people, who moved south from present-day Ethiopia; Eastern Cushitic people who moved into Tanzania from north of Lake Turkana about 2,000 and 4,000 years ago; and the Southern Nilotes, including the Datoog, who originated from the present-day South Sudan–Ethiopia border region between 2,900 and 2,400 years ago. These movements took place at about the same time as the settlement of the Mashariki Bantu from West Africa in the Lake Victoria and Lake Tanganyika areas. In the late 19th century, the mainland came under German rule as German East Africa. This was followed by British rule after World War I when it was governed as Tanganyika, with the Zanzibar Archipelago remaining a separate colonial jurisdiction. Following their gaining respective independence in 1961 and 1963, the two entities merged in 1964 to form the United Republic of Tanzania.

The Swahili people (Swahili: Waswahili, وَسوَحِيلِ) comprise mainly Bantu, Afro-Arab, and Comorian ethnic groups inhabiting the Swahili coast, an area encompassing the East African coast across southern Somalia, Kenya, Tanzania, and northern Mozambique, and various archipelagos off the coast, such as Zanzibar, Lamu, and the Comoro Islands.

The original Swahili distinguished themselves from other Bantu peoples by self-identifying as Waungwana (the civilised ones). In certain regions, such as Lamu Island, this differentiation is even more stratified in terms of societal grouping and dialect, hinting at the historical processes by which the Swahili have coalesced over time. More recently, through a process of Swahilization, this identity extends to any person of African descent who speaks Swahili as their first language, is Muslim, and lives in a town of the main urban centres of most of modern-day Tanzania and coastal Kenya, northern Mozambique, or the Comoros.

The Sultanate of Zanzibar (Swahili: Usultani wa Zanzibar, Arabic: سلطنة زنجبار, romanized: Sulṭanat Zanjībār), also known as the Zanzibar Sultanate, was an East African Muslim state controlled by the Sultan of Zanzibar, in place between 1856 and 1964. The Sultanate's territories varied over time, and after a period of decline, the state had sovereignty over only the Zanzibar Archipelago and a 16-kilometre-wide (10 mi) strip along the Kenyan coast, with the interior of Kenya constituting the British Kenya Colony and the coastal strip administered as a de facto part of that colony.

Under an agreement reached on 8 October 1963, the Sultan of Zanzibar relinquished sovereignty over his remaining territory on the mainland, and on 12 December 1963, Kenya officially obtained independence from the British. On 12 January 1964, revolutionaries, led by the African Afro-Shirazi Party, overthrew the mainly Arab government. Jamshid bin Abdullah, the last sultan, was deposed and lost sovereignty over Zanzibar, marking the end of the Sultanate, and resulted in the massacre of tens of thousands of Arabs. It was also involved in the shortest war in history, the Anglo-Zanzibar War, which lasted 38 minutes.

Slavery existed in the Sultanate of Zanzibar until 1909. Slavery and slave trade existed in the Zanzibar Archipelago for at least a thousand years. During the 19th century, the rise of large-scale clove and coconut plantations under Omani Arab rule led to a significant expansion of the slave system. By some estimates, enslaved people constituted up to two-thirds of the archipelago's population at its peak. Zanzibar was internationally known as a major player in the Indian Ocean slave trade, where slaves from the Swahili coast of Eastern Africa were trafficked across the Indian Ocean to Oman in the Arabian Peninsula during the Zanzibar slave trade.

During the 19th-century, Britain conducted an international abolitionist campaign against the Sultanate and restricted and eventually abolished the slavery and slave trade in Zanzibar via a number of treaties between 1822 and 1897, resulting in the end of the slave trade and finally the end of slavery itself in 1909.

Pemba Island (Arabic: الجزيرة الخضراء, al-Jazīra al-khadrāʔ; Swahili: Kisiwa cha Pemba) is a Tanzanian island forming part of the Zanzibar Archipelago, lying within the Swahili Coast in the Indian Ocean.

Zanzibar City or Mjini District, often simply referred to as Zanzibar (Wilaya ya Zanzibar Mjini or Jiji la Zanzibar in Swahili), is one of two administrative districts of Mjini Magharibi Region in Tanzania. The district covers an area of 15.4 km (5.9 sq mi). The district is comparable in size to the land area of Nauru. The district has a water border to the west by the Indian Ocean. The district is bordered to the east by Magharibi District. The district seat is in Stonetown. The city is the largest on the island of Zanzibar. It is located on the west coast of Unguja, the main island of the Zanzibar Archipelago, north of the much larger city of Dar es Salaam across the Zanzibar Channel. The city also serves as the capital of the Zanzibar Urban/West Region. In 2022 its population was 219,007.

Zanzibar City comprises two main parts, Stone Town and Ng'ambo (literally: "The Other Side"); the two areas were historically divided by a creek since filled in, with the street on the Stone Town side of the creek originally called Creek Road but later renamed to Benjamin Mkapa Road. Stone Town is the historical core of the city, the former capital of the Zanzibar Sultanate; because of its unique architecture and culture, it was declared a UNESCO World Heritage Site in 2000. Ng'ambo is a much larger, modern area that developed around Stone Town after the Zanzibar Revolution, with office buildings and large apartment blocks such as those of the Michenzani neighbourhood. Zanzibar City is served by a number of international and domestic airlines via Abeid Amani Karume International Airport.

Stonetown of Zanzibar (Arabic: مدينة زنجبار الحجرية, romanized: madīnat Zanjibār al-ḥajariyya), also known as Mji Mkongwe (Swahili for 'old town'), is the old part of Zanzibar City, the main city of Zanzibar, in Tanzania. The newer portion of the city is known as Ng'ambo, Swahili for 'the other side'. Stone Town is located on the western coast of Unguja, the main island of the Zanzibar Archipelago. Former capital of the Zanzibar Sultanate, and flourishing centre of the spice trade as well as the Indian Ocean slave trade in the 19th century, it retained its importance as the main city of Zanzibar during the period of the British protectorate. When Tanganyika and Zanzibar joined each other to form the United Republic of Tanzania, Zanzibar kept a semi-autonomous status, with Stone Town as its local government seat.

Stone Town is a city of prominent historical and artistic importance in East Africa. Its architecture, mostly dating back to the 19th century, reflects the diverse influences underlying the Swahili culture, giving a unique mixture of Arab, Persian, Indian and European elements. For this reason, the town was designated as a UNESCO World Heritage Site in 2000.

Abeid Amani Karume International Airport (Swahili: Uwanja wa Ndege wa Kimataifa wa Abeid Amani Karume, IATA: ZNZ, ICAO: HTZA) is the main airport in the Zanzibar Archipelago located on Unguja Island, Zanzibar, Tanzania. It is approximately 5 kilometres (3.1 mi) south of Zanzibar City, the capital of Zanzibar, and has flights to East Africa, Europe, and the Middle East. It was previously known as Kisauni Airport and Zanzibar International Airport. It was renamed in 2010 in honour of Abeid Amani Karume, the island's first president.
