The Houthi takeover in Yemen, also known as the September 21 Revolution (by supporters), or 2014–15 coup d'état (by opponents), was a popular revolution against Yemeni President Abdrabbuh Mansur Hadi led by the Houthis and their supporters that pushed the Yemeni government from power. It had origins in Houthi-led protests that began the previous month, and escalated when the Houthis stormed the Yemeni capital Sana'a on 21 September 2014, causing the resignation of Prime Minister Mohammed Basindawa, and later the resignation of President Abdrabbuh Mansur Hadi and his ministers on 22 January 2015 after Houthi forces seized the presidential palace, residence, and key military installations, and the formation of a ruling council by Houthi militants on 6 February 2015.
