One of the most important changes Charlemagne made was abandoning the gold standard and putting all of Europe on the same silver currency. Trade became easier and the continent prospered, aided by laws that took some power away from the nobles and let the peasantry participate in commerce. 

The three steps before modern english were indo-european, germanic, and old english. as peoples moved around the eurasian continent, their languages changed. throughout the ages, the languages became more specialized. as english has many germanic influences, it is easy to see how this was one of the forebears. also, old english was one of the main ancestors of the modern language, spoken in the 5th through about the 13th centuries.
