What is the tie between the Vikings and the vast amount of Latin based words in the English language?

In the 9th and 10th centuries the Viking invaded parts of England and Scotland. The language spoken at the time was Old English. The Viking invaders began using Old English words along with their own language Old Norse. The languages mixed and gave us many of the commonly used words we use today. Latin was the commonly spoken language in Europe at the time. The European priests converted the Anglo Saxons and spread Latin. When these Normans invaded, they brought many of their Latin based words with them also. All these languages came together to form our modern English language spoken widely today.
