Sharia4 Network
The Sharia4 network is a radical Islamist recruitment network based out of Europe and was most active in the early 2010s. The network was largely informal, though there were active branches in Belgium, the United Kingdom and the Netherlands. These networks were inspired by Islam4UK, an extremist pipeline set up by British radical cleric Anjem Choudary. The Sharia4 networks proved effective at radicalizing and recruiting young Europeans to join ISIS.
