I think most people don’t know anything about the Houthi.
“According to Ahmed Addaghashi, a professor at Sanaa University, the Houthis began as a moderate theological movement that preached tolerance and held a broad-minded view of all the Yemeni peoples. Their first organization, “the Believing Youth” (BY), was founded in 1992 in Saada Governorate: 1008 by either Mohammed al-Houthi,: 98 or his brother Hussein al-Houthi.”
The Yemen government has neglected sharing wealth with the north. This what provided the Houthi movement the reasons to exist.
