The Houthis, also known as Ansar Allah (or “supporters of God”), are a violent militia group that currently exercise de facto control over much of northern Yemen. Formed in the 1990s, the group was named after its founder, Hussein Badreddin al-Houthi, and they follow the Zaidi branch of Shia Islam which represents 20-30% of Yemen’s population.
