During the European Dark Ages, between the 7th and 14th century AD, the Moorish Empire in Spain became one of the world's finest civilizations.
General Tarik and his Black Moorish army from Morocco, conquered Spain after a week long battle with King Roderick in 711 AD. (The word tariff and the Rock of Gibraltar were named after him). They found that Europe, with the assistance of the Catholic Church, had returned almost to complete barbarism.
The population was 90% illiterate and had lost all of the civilizing principles that were passed on by the ancient Greeks and Romans.
The Moors reintroduced mathematics, medicine, agriculture, and the physical sciences. The clumsy Roman numerals were replaced by Arabic figures including the zero and the decimal point. As Dr. Van Sertima says, "You can't do higher mathematics with Roman numerals."
The Moors introduced agriculture to Europe including cotton, rice, sugar cane, dates, ginger, lemons, and strawberries. They also taught them how to store grain for up to 100 years and built underground grain silos.
