This social and industrial state of the Yorubas formerly spread and wielded great influence. We find Yoruba reaching out and subduing states like Nupe toward the northward. But the industrial democracy and city autonomy of Yoruba lent itself indifferently to conquest, and the state fell eventually a victim to the fanatical Fula Mohammedans and was made a part of the modern sultanate of Gando. West of Yoruba on the lower courses of the Niger is Benin, an ancient state which in 1897 traced its twenty-three kings back one thousand years; some legends even named a line of sixty kings. It seems probable that Benin developed the imperial idea and once extended its rule into the Congo valley. Later and also to the west of the Yoruba come two states showing a fiercer and ruder culture, Dahomey and Ashanti. The state of Dahomey was founded by Tacondomi early in the seventeenth century, and developed into a fierce and bloody tyranny with wholesale murder. The king had a body of two thousand to five thousand Amazons renowned for their bravery and armed with rifles. The kingdom was overthrown by the French in 1892-93. Under Sai Tutu, Ashanti arose to power in the seventeenth century. A military aristocracy with cruel blood sacrifices was formed. By 1816 the king had at his disposal two hundred thousand soldiers. The Ashanti power was crushed by the English in the war of 1873-74. In these states and in later years in Benin the whole character of west-coast culture seems to change. In place of the Yoruban culture, with its city democracy, its elevated religious ideas, its finely organized industry, and its noble art, came Ashanti and Dahomey. What was it that changed the character of the west coast from this to the orgies of war and blood sacrifice which we read of later in these lands? There can be but one answer: the slave trade. Not simply the sale of men, but an organized traffic of such proportions and widely organized ramifications as to turn the attention and energies of men from nearly all other industries, encourage war and all the cruelest passions of war, and concentrate this traffic in precisely that part of Africa farthest from the ancient Mediterranean lines of trade. We need not assume that the cultural change was sudden or absolute. Ancient Yoruba had the cruelty of a semi-civilized land, but it was not dominant or tyrannical. Modern Benin and Dahomey showed traces of skill, culture, and industry along with inexplicable cruelty and bloodthirstiness. But it was the slave trade that turned the balance and set these lands backward. Dahomey was the last word in a series of human disasters which began with the defeat of the Askias at Tenkadibou.[26]
