" The map of the medieval world was constantly changing, as various kingdoms, principalities and states fought each other and redrew borders. In Europe and western Asia there were many states that rose to power and then later fell. Some of the most well-known ones include the Holy Roman Empire, the Kingdom of Jerusalem and the Abbasid Caliphate. Here, we take a look at 10 of the lesser known kingdoms that no longer exist."
Europe in the first half of the 14th Century seemed to be preparing itself for significant changes. Cities grew in importance, though most of the population was still rural. Population increases had led to overuse of the available land. Poor harvests-also due to cooler, wetter weather-led to famines. The serf system was being undermined. Centralized political authority was becoming more powerful. Then the Black Death cut a path-both literal and figurative-through the middle of the 14th Century. The disease was caused by the bubonic plague, which was spread by rats, whose fleas carried the plague bacilli from the East along trade routes until it penetrated almost all of Europe, killing at least one out of every three people.
Such a radical alteration in population in any place, at any time, would likely set off dramatic changes in society. What happened in a Europe already beginning to transform itself? In this lesson, students analyze maps, firsthand accounts, and archival documents to trace the path and aftermath of the Black Death.

"In 1187, thirty-three years after al-Idrisi drew his World Map, and forty-two years after the Second Crusaders returned, a Third Crusade set off for the Holy Land. By that time the soldiers from the Second Crusade were sixty-year-old men or older."
Springing from the Classical Atlas Project and the Barrington Atlas of the Greek and Roman World, Pleiades is a historical gazetteer and more. It associates names and locations in time and provides structured information about the quality and provenance of these entities. There is also a graph in Pleiades: names and locations are collected within places and these collections are associated with other geographically connected places. Pleiades also serves as a vocabulary for talking about the geography of the ancient world within Linked Data sets and is referenced by research projects such as Google Ancient Places and PELAGIOS.
