The Houthis, a Yemeni political and military organisation, have made headlines across the World since they began blocking the Red Sea nearly six months ago. But despite their association in people's minds with Gaza, and Iran's "Axis of Resistance", their true motives are poorly understood.

This is the second half of a two-part conversation seeking to explain the Houthis' influence in Yemeni politics and society. Today's episode deals with the period since 2013, and especially since the outbreak of civil war in Yemen in 2014.

How have the Houthis gone from being an obscure group in the mountainous region of Northern Yemen to controlling two thirds of the country’s population? And most importantly of all, how have the Houthis managed to fend off a US-backed alliance comprised of the armed forces of Saudi Arabia, the UAE and Qatar?

As was the case in Part 1, my guest for this conversation is Isa Blumi. Isa is an associate professor of Turkish and Middle Eastern Studies at Stockholm University. Isa has published several books on Turkey, the Balkans, the late Ottoman Empire and Yemen, including Destroying Yemen: What Chaos in Arabia Tells Us about the World.
