A network built from marriages in the game grouped by dynasty. This is the largest network in the game, there are a number of other smaller networks (<10 nodes) that are not connected to this one.
The network is colored by the modularity statistic in Gephi. Nodes that share a color belong to the same cluster and are more connected to each other than to nodes in other clusters. India forms a cluster at the top right and all Europe forms one on the bottom left. The light green cluster connected to this represents the the pagan regions around the Baltic Sea and Russia. It is mainly Scandinavian dynasties that are married into the European cluster. Spain, West and parts of North Africa form a single cluster on the far right and the light blue cluster, which looks like it could split in two, shows that there is a strong connection between the North Africian\Egyptian Ismalic dynasties (joining the dark green cluster) and thoses of the Middle East (joining the Indian cluster). The brown cluster on the left is Greece and Byzantium which converted to Islam early in this game.
Hover over a node to get its name, culture and religion or click on a node to see its ego network. Due to the size of this network it can take a while longer to load or zoom in on.
