The Spice Islands of the Indian Ocean
Zanzibar is a semi-autonomous archipelago in the western Indian Ocean, roughly 35 kilometres off the coast of Tanzania in East Africa. To most visitors the name conjures turquoise water and white sand, but Zanzibar is more layered than a postcard destination. It is an ancient trading hub, a UNESCO World Heritage city, a living Islamic society, a spice-producing economy, and one of the most biodiversity-rich marine environments in the Indian Ocean — all compressed onto a pair of coral limestone islands barely 85 kilometres long.
The main island, Unguja, is what most people mean when they say "Zanzibar." Pemba Island, 80 kilometres to the north, is quieter and less touristed. Together they form the Zanzibar Archipelago, a special administrative region of Tanzania with its own president, parliament, and government — not a separate country, but more than simply a provincial district.
Geography and landscape
Unguja is flat by East African standards — the highest point barely reaches 120 metres — with a coral limestone base overlaid by sandy soil and, in the centre of the island, pockets of native forest. The western coast faces the Zanzibar Channel and the Tanzania mainland; the eastern coast faces the open Indian Ocean across a fringing reef. The north coast has calm, sandy beaches; the east coast has longer, breezier stretches ideal for kitesurfing.
The interior is agricultural: clove and coconut plantations cover large parts of the island, spice farms grow black pepper, cinnamon, nutmeg, and vanilla, and Jozani Chakawa Bay National Park in the south-centre protects the island's remaining indigenous forest and its endemic Zanzibar red colobus monkey.
A short history
People have lived on Unguja for at least two millennia, but Zanzibar's role as a major Indian Ocean entrepôt accelerated from around the 9th and 10th centuries CE, when Arab traders began to establish permanent settlements. The monsoon winds made the passage between the Arabian Peninsula and the East African coast predictable and reliable: the northeast monsoon brought ships south from November to March; the southwest monsoon pushed them back north from May to October.
By the 13th century, Zanzibar was part of a network of Swahili city-states stretching from Mogadishu to Mozambique. Portuguese mariners arrived in the early 16th century and disrupted existing trade networks, but their hold on Zanzibar was never firm. By the late 17th century, the Omani Sultanate had expelled the Portuguese from the East African coast and established dominance. In 1832, Sultan Seyyid Said moved his capital from Muscat to Zanzibar, making the island the centre of one of the Indian Ocean world's most powerful commercial empires, built on the trade in ivory, cloves, and enslaved people.
The clove economy established during the Sultanate era defined Zanzibar through the colonial period. Britain declared Zanzibar a protectorate in 1890 and administered it separately from the mainland colony of Tanganyika. Independence came in December 1963; revolution came a month later in January 1964, ending the Sultanate; and union with Tanganyika to form Tanzania followed in April 1964.
Stone Town
Stone Town, on the western tip of Unguja, is the historic heart of Zanzibar and one of the most intact examples of Swahili coastal architecture in existence. In 2000 it was designated a UNESCO World Heritage Site. The city is a dense tangle of narrow coral-stone lanes, carved wooden doorways (which indicate status by their size and complexity of carving), old mosques, Indian merchant houses, colonial administrative buildings, and the waterfront Forodhani Gardens where vendors sell grilled seafood each evening.
The Old Fort — a 17th-century Arab fortification — stands at the edge of the seafront. The House of Wonders (Beit al-Ajaib), once the Sultan's ceremonial palace, remains one of Stone Town's most distinctive structures. Freddie Mercury, lead singer of Queen, was born in Stone Town in 1946 as Farrokh Bulsara, and a small museum now marks his connection to the city.
Beaches and marine life
Zanzibar's beaches have made it one of the Indian Ocean's most visited island destinations. The north coast beaches at Nungwi and Kendwa are calm year-round. The east coast at Paje and Jambiani offers long stretches of white sand with a tidal reef lagoon. Mnemba Atoll, a private atoll off the northeast coast, is widely considered one of East Africa's finest dive sites, with excellent populations of reef fish, turtles, and dolphins.
Zanzibar as a travel destination
Modern Zanzibar receives several hundred thousand international visitors a year. The tourism infrastructure spans the full spectrum — from backpacker guesthouses in Stone Town's alleys to luxury private villas on the north coast. Beyond the beach, visitors come for spice farm tours, dolphin swimming at Kizimkazi, diving, Stone Town's history, and the general experience of a place that is unlike anywhere else in East Africa.
