The westernmost point of the African continent marks a region where human settlement predates recorded history by millennia. Stone circles at Wassu and Sine Ngayène, dating between 300 BCE and 1600 CE, indicate organized societies capable of quarrying, transporting, and erecting laterite pillars weighing up to ten tons. The Senegambia Stone Circles, spanning areas in both Senegal and neighboring Gambia, represent over 1,000 monuments distributed across 30,000 square kilometers. Archaeological evidence from shell middens along the Petite Côte demonstrates continuous human habitation from at least 5,000 years ago, with fishing communities exploiting seasonal marine resources.
The Tekrur kingdom emerged along the Senegal River valley by the ninth century CE, becoming one of the first West African states to adopt Islam under War Jabi around 1030-1040. Tekrur controlled trans-Saharan trade routes carrying gold, salt, and slaves between the Bambuk goldfields and North African markets. The kingdom's conversion established a pattern that would define Senegalese society: the coexistence of Islamic practice with pre-existing social structures. By the thirteenth century, the Mali Empire absorbed Tekrur's territories, extending Manding influence across the region and introducing the Mandinka population that still inhabits eastern Senegal.
The Jolof Empire consolidated power across the Wolof-speaking areas between the thirteenth and fifteenth centuries, controlling a confederation that included the kingdoms of Waalo, Cayor, Baol, Sine, and Saloum. At its peak around 1350, Jolof's buurba (emperor) commanded tribute from an area stretching from the Senegal River to the Gambia River. The empire fragmented in the mid-sixteenth century when Cayor and other vassal states declared independence following succession disputes and Portuguese disruption of trade monopolies. The decentralization created a patchwork of kingdoms that European traders exploited during the subsequent three centuries.
Portuguese navigator Dinis Dias reached the Cape Verde Peninsula in 1444, documenting the Lebou fishing communities that controlled access to the volcanic peninsula. The Portuguese established a trading post on Gorée Island in 1444, initiating European involvement in a region where Wolof, Serer, and Mandinka kingdoms competed for resources and trade revenue. Dutch forces seized Gorée in 1588, followed by British occupation in 1664, before French control was established in 1677. The island's strategic harbor made it a contested asset during European naval conflicts, changing hands between Britain and France fourteen times between 1677 and 1815.
French merchants founded Saint-Louis at the mouth of the Senegal River in 1659, creating the oldest European settlement in West Africa. The town became capital of French West Africa in 1895, housing colonial administrators who governed territories from Mauritania to Chad. The unique architecture of Saint-Louis developed from Franco-African unions, producing a Métis community that served as intermediaries between European trading houses and African kingdoms. By 1850, Saint-Louis had grown to approximately 15,000 inhabitants, making it one of the largest cities in West Africa. The island's narrow configuration, measuring only 2 kilometers long and 400 meters wide, forced dense construction of two-story buildings with characteristic wooden balconies and jalousies.
The Atlantic slave trade transformed Senegalese societies between 1500 and 1850. Gorée Island's House of Slaves, built by the Dutch around 1776, represents the final phase of a commerce that shipped an estimated 200,000 enslaved persons through the island according to documentation at the site, though historians debate whether this figure represents all captives processed there or only those from specific periods. The trade created economic dependencies that reshaped political structures. Cayor's damel Lat Dior Diop initially collaborated with French merchants before resisting colonial expansion in the 1860s. Lat Dior fought French forces in multiple battles between 1862 and 1886, refusing to allow construction of the Dakar-Saint-Louis railway through Cayor territory. He died in battle at Dekhele on October 26, 1886, becoming a symbol of resistance to colonial domination.
France extended formal colonial control through military campaigns between 1854 and 1890 under Governor Louis Faidherbe. Faidherbe established forts along the Senegal River at Médine, Matam, and Podor, pacifying Futa Toro and opening routes to the interior. The Four Communes of Gorée, Dakar, Rufisque, and Saint-Louis received special status in 1848, granting residents French citizenship and voting rights. This created a political anomaly where African residents of these communes could vote in French elections and serve in the French parliament while Africans elsewhere in French West Africa held subject status. Blaise Diagne became the first African elected to the French Chamber of Deputies in 1914, representing Senegal until 1934 and advocating for expanded citizenship rights.
The Mouride brotherhood transformed Senegalese Islam beginning in 1883 when Cheikh Ahmadou Bamba Mbacké began preaching in Baol. Bamba emphasized work, particularly agricultural labor, as a form of religious devotion. French authorities viewed the movement's hierarchical structure and Bamba's influence over followers as a threat to colonial order. They exiled him to Gabon from 1895 to 1902, then to Mauritania from 1903 to 1907. These exiles strengthened rather than diminished his following. Upon his return, Bamba established Touba as the brotherhood's spiritual center in 1887. The Grand Mosque of Touba, constructed between 1963 and 1963, stands 87 meters tall with a capacity of 15,000 worshippers. Annual pilgrimages to Touba during the Grand Magal, commemorating Bamba's 1895 exile, now attract over three million participants according to Senegalese government estimates from 2019.
The Tijaniyya brotherhood, established in North Africa in the eighteenth century, gained Senegalese adherents through El Hadj Malick Sy beginning in 1902. Sy founded a zawiya (religious school) at Tivaouane that attracted students from across French West Africa. The Tijaniyya adopted a more accommodating stance toward French authority than the Mourides, facilitating colonial administration while maintaining religious autonomy. Sy's descendants continue to lead the Tivaouane branch, with the annual Maouloud celebration drawing approximately one million pilgrims according to 2018 attendance figures. The division between Mouride and Tijaniyya allegiances, along with smaller Qadiriyya and Layene brotherhoods, structures Senegalese politics and social networks. Approximately 95 percent of Senegal's population practices Islam, with the remaining 5 percent predominantly Catholic.
Léopold Sédar Senghor emerged as Senegal's defining political figure through his dual roles as poet and statesman. Born October 9, 1906, in Joal to a Serer Catholic family, Senghor studied at the Sorbonne where he developed the Négritude movement with Martinican poet Aimé Césaire in the 1930s. Négritude asserted the value and beauty of African culture against French assimilationist ideology. Senghor served in the French army, was captured during World War II, and spent two years in German prisoner-of-war camps. He won election to the French Constituent Assembly in 1945, representing Senegal until independence. As president from 1960 to 1980, Senghor maintained close economic and cultural ties with France while promoting African socialism adapted to Senegalese conditions. He voluntarily retired in 1980, the first African leader to transfer power peacefully, and became the first African elected to the Académie Française in 1983.
Independence from France occurred on April 4, 1960, following the collapse of the Mali Federation. Senegal and French Sudan (modern Mali) had merged into the federation on January 17, 1959, gaining independence from France on June 20, 1960. Constitutional disputes between Senghor and Sudanese leader Modibo Keïta over the federation's future led to its dissolution on August 20, 1960. Senegal declared full sovereignty as a separate republic, while Sudan took the name Mali. The brief federation left a legacy of tension between the two nations that persisted through the 1960s.
