Sanaa, officially the Sanaa Municipality, is the capital and largest city of Yemen. The city is the capital of the Sanaa Governorate, but is not part of the governorate, as it forms a separate administrative unit. According to the Yemeni constitution, Sanaa is the capital of the country, although the seat of the Yemeni government moved to Aden, the former capital of Democratic Yemen, in the aftermath of the Houthi occupation. Aden was declared the temporary capital by then-president Abdrabbuh Mansur Hadi in March 2015.
