A civil war has been raging in the republic in the south of the Arabian Peninsula since the Houthi rebels and their allies took control of the capital Sanaa in September 2014. They are opposed by the internationally recognised government-in-exile of interim President Hadi, who has been supported by a coalition led by Saudi Arabia since March 2015. The war has already claimed over 230,000 lives, more than 130,000 of them from indirect causes such as lack of food and dysfunctional health care. Less than half of Yemen's 27 million people still have access to clean water and sufficient food, and 80 per cent of the population is dependent on international aid supplies. In addition to Corona, the country has been struggling with a cholera epidemic, diphtheria and dengue fever for years.

The year 2011 had initially brought a glimmer of hope for the country, which has been plagued by recurring violence and economic hardship for decades. In the course of the “Arab Spring”, tens of thousands of people protested in Sanaa against corruption and for political and economic reforms. The autocratic long-term president Saleh was forced to step down, and in 2013 a UN-supported national dialogue process began that was supposed to lay the foundations for a federal and democratic Yemen. But the transition failed. The Zaidite-Shiite Houthi rebels from the north and groups loyal to Saleh from the security apparatus took advantage of the population's dissatisfaction with the transitional government and were able to bring large parts of the country, including the capital, under their control by force. At the same time, representatives of southern Yemen demanded and still demand independence for the south; from 1967 to 1990, the southern parts of the country were an independent, Marxist-oriented state ruled by a socialist unity party as the People's Democratic Republic of Yemen.

With the support of the Saudi-led military coalition and United Arab Emirates troops on the ground, the capture of the southern port city of Aden by the Houthis and their allies was prevented. But the capital and populous areas in the north and northwest remain under their control. After former President Saleh stood up to the Houthis, with whom he had previously allied against the interim government, he was killed by them in Sanaa in early December 2017. Beyond the internal Yemeni power struggles, the country has increasingly become the scene of a regional power struggle. Saudi Arabia sees the Houthis as a Tehran-backed militia, with Iran now continuing its expansionist drive in the Arab region along Saudi Arabia's southern border. The intertwining of sub-state-tribal, national and regional lines of conflict makes it difficult to find a solution to the Yemen crisis and calls for a comprehensive approach by the international community and increased and coordinated engagement by Germany and the EU.
