# Maritime history of Africa

African maritime history and navigation encompass various traditions of seafaring, trade, and navigation across the African continent, particularly along its extensive coastlines and among island communities. This history highlights the interconnectedness of African societies with the broader world through the Indian Ocean, Atlantic Ocean, and Mediterranean Sea trade routes.

## Early maritime activities
### East African Coast

The East African coast, particularly the Swahili Coast, has a long history of maritime activities. The Swahili people, whose culture emerged from a blend of African, Arabian, Persian, and Indian influences, were adept sailors and traders. They constructed dhows, traditional wooden sailing vessels, which facilitated trade across the Indian Ocean. These dhows played a crucial role in connecting the Swahili Coast with the Arabian Peninsula, India, and Southeast Asia. Key Swahili city-states such as Kilwa, Mombasa, and Zanzibar thrived as commercial hubs, trading goods like gold, ivory, slaves, and spices. The Swahili language, a Bantu language with significant Arabic influence, emerged as a lingua franca of trade in the region.

### Egypt and Nubia

In Northeast Africa, ancient Egypt and Nubia (modern-day Sudan) developed significant maritime capabilities. The Nile River served as a vital artery for transport and trade, with Egyptians using boats made of papyrus reeds and later, wooden vessels. These boats facilitated the movement of goods and people along the river and into the Mediterranean Sea. Egyptian maritime activities extended into the Red Sea, where they engaged in trade expeditions to Punt, in the Horn of Africa. These expeditions brought back valuable commodities such as myrrh, frankincense, and gold. The naval prowess of the Egyptians also included military campaigns and exploration missions.

## Key maritime trade routes
### Indian Ocean trade
#### Swahili City-States

The Indian Ocean trade network was a major conduit for economic and cultural exchanges between Africa, Arabia, India, and Southeast Asia. Swahili city-states like Kilwa, Mombasa, and Zanzibar were pivotal in this network. These cities became prosperous trading centres where African goods such as gold, ivory, and slaves were exchanged for Arabian and Indian textiles, spices, and ceramics. The wealth and cosmopolitan nature of these city-states are evident in their archaeological remains, including grand stone buildings, mosques, and tombs.

#### Monsoon winds

The monsoon winds, which blow from the northeast during the winter and from the southwest during the summer, were vital for maritime travel in the Indian Ocean. These predictable wind patterns allowed sailors to plan their voyages with relative certainty. African, Arabian, and Indian traders used these winds to travel to and from the East African coast, facilitating regular and efficient trade.

## Transatlantic navigation
### West African seafaring

On the West African coast, maritime activities included fishing, coastal trade, and interactions with European traders. West African societies such as the Akan, Yoruba, and Igbo engaged in local and regional trade using canoes and larger boats. These maritime practices were well-established by the time Portuguese explorers arrived in the 15th century. The Portuguese, followed by other European powers, established trade relations with West African societies, exchanging European goods for African gold, ivory, and slaves. Key ports like Elmina (in present-day Ghana) became central to these transatlantic exchanges.

### Slave trade

The transatlantic slave trade had a great impact on African maritime history. West African ports became key departure points for millions of Africans forcibly transported to the Americas. The involvement of African intermediaries, who supplied slaves to European traders, was a complex aspect of this maritime history. European ships, known as slavers, were specially designed to transport large numbers of enslaved Africans across the Atlantic. This trade had devastating effects on African societies but also underscored the maritime skills and networks that existed on the continent.

## Maritime technologies and shipbuilding
### Indigenous shipbuilding techniques
#### Dhow construction

Dhows are iconic vessels of the Indian Ocean, characterized by their slender, curved hulls and lateen sails. The construction of dhows involved skilled craftsmanship using locally sourced materials such as mangrove timber. These vessels were well-suited for the conditions of the Indian Ocean, enabling long-distance trade. The techniques used in dhow construction were passed down through generations, reflecting a deep understanding of maritime engineering and navigation. Dhows remain a symbol of the rich maritime heritage of the Swahili Coast.

#### Canoes and boats

Inland and coastal regions across Africa utilized a variety of canoes and boats, crafted from hollowed-out logs or assembled from planks. These vessels were essential for fishing, transportation, and trade along rivers, lakes, and coastal waters. Different regions developed distinct styles of boat building, reflecting their specific environmental and cultural contexts. For instance, the Buganda people around Lake Victoria crafted large canoes capable of carrying significant cargo and passengers, while the Niger Delta communities built boats designed for navigating intricate waterways.

## Cultural and economic impact
### Cultural exchanges
#### Language and religion

Maritime trade facilitated significant cultural exchanges across Africa. The spread of the Swahili language along the East African coast is a testament to these interactions. As a Bantu language enriched with Arabic vocabulary, Swahili became the lingua franca of trade and communication in the region. Similarly, the spread of Islam along the East African coast was closely tied to maritime trade. Traders and sailors from the Arabian Peninsula brought Islam with them, leading to the establishment of Muslim communities and the construction of mosques in coastal cities.

#### Cultural diffusion

The movement of people and goods through maritime trade also led to the diffusion of cultural practices, art, cuisine, and architecture. African art forms, such as the intricate wood carvings of the Swahili and the beadwork of the Yoruba, often incorporated influences from other cultures encountered through trade.
Architectural styles in coastal cities, including the use of coral stone and the design of grand houses and mosques, reflect a blend of African, Arabian, and Persian influences. These cultural exchanges enriched the local traditions and contributed to a vibrant and diverse cultural landscape.

### Economic networks
#### Trade goods

African maritime trade involved a wide range of goods that were highly valued in international markets. From the East African coast, gold, ivory, and slaves were prominent exports. In return, African traders received textiles, ceramics, spices, and other luxury goods from Arabia, India, and beyond. In West Africa, gold from the Akan forests, ivory, and later slaves were significant exports, exchanged for European goods such as firearms, cloth, and alcohol.

#### Economic influence

The economic influence of maritime trade on African societies was evident. Coastal cities and kingdoms that engaged in maritime trade often became wealthy and powerful. The revenues generated from trade supported the development of urban centres, the construction of impressive architecture, and the patronage of the arts. However, the negative impacts, particularly of the transatlantic slave trade, cannot be overlooked. The loss of human capital and the societal disruptions caused by the slave trade had long-lasting detrimental effects on African communities.
