The Houthi rebels, formally known as Ansar Allah, are a Zaidi Shia-led political and armed movement originating from northern Yemen. They emerged in the 1990s and became a significant force during the Yemeni Civil War, which intensified after their takeover of the capital, Sana'a, in 2014. Their rise has been heavily influenced by regional conflicts, international interventions, and the broader geopolitical landscape of the Middle East.
