Now, as we fast forward a little over a decade, as we get to the middle of the 12th century, you do have the Muslims being able to take back some of the territory, in particular, Edessa and Aleppo. And so this bonds what will eventually be known as the Second Crusade, and it's really the second of many Crusades. Now, these are what historians consider the official numbered Crusades, but there were many other Crusades in this time period, in roughly this 200-year time period during the High Middle Ages. You had Crusades against Germanic non-Christians in Northern Europe. You had Crusades in Spain in order to retake land from the Muslims, which they had for several hundred years, what's known as the Reconquista. So after Aleppo and Edessa were taken, you have the Second Crusades, which end up being quite unsuccessful, and it really doesn't change what the Middle East looks like. But then as you get to the end of the 12th century, you have a significant event.
