Syrian Kurdistan or Western Kurdistan refers to an area in the Middle East, located in northern and north-eastern Syria. The term is a Kurdish nationalist description of a geographic area, historically populated by Kurds, and included in the Syrian state by French Mandatory authorities following WWI. Since 2012, much of the Syrian Kurdistan came to be controlled by Kurdish militant groups as part of the Syrian civil war.
Under the administration of the Kurdish Supreme Committee, the Popular Protection Units (YPG) were created to control the Kurdish inhabited areas in Syria. On 19 July, the YPG captured the city of Kobanê (Ayn al-Arab), and the next day captured Amûdê and Efrîn. The KNC and PYD afterwards formed a joint leadership council to run the captured cities. By 24 July, the Syrian Kurdish cities of Dêrika Hemko (Al-Malikiyah), Serê Kaniyê (Ra's al-'Ayn), Dirbêsî (Al-Darbasiyah) and Girkê Legê (Al-Ma'bada) had also come under the control of the Popular Protection Units. The only major Kurdish inhabited cities that remained under government control were Hasaka and Qamishli.
