Marka people
The Marka (also Marka Dafing, Meka, or Maraka) people are a Mande people of northwest Mali. They speak the Marka language, a Manding language. Some of the Maraka (Dafin people are found in Ghana. History
The Marka originated from Soninke people from Wagadu Empire who migrated to the middle Niger between the 11th and 13th centuries. The term 'Maraka' means 'men who rule' in Bambara, which may have originated as a term for the colonists from Wagadu or merely as a term of respect. Relatively geographically constrained compared to other trading communities such as the Jakhanke and Dyula people, they founded Nyamina and Sansanding during this early period, and Barouéli and Banamba in the 19th century. All four were at various times prominent trading and religious centers. Muslim merchant communities at the time of the Bambara Empire, the Maraka largely controlled the desert-side trade between the Sahel and nomadic Berbers and Moors of the Sahara. Their economy was based on slave plantation agriculture growing food and cotton to be traded. The Bambara integrated Maraka communities into their state structure, and Maraka trading posts and plantations multiplied in the Segu based state and its Kaarta vassals in the 18th and early 19th centuries. When the pagan Bambara empire was defeated by the Maraka's fellow Muslim Umar Tall in the 1850s, the Maraka's unique trade and landholdings concessions suffered damage from which they never recovered. Today
Today there are only around 25,000 Marka speakers, and they are largely integrated amongst their Soninke and Bambara neighbors. Culture 
The Marka people are adherents of Islam. References
