the agreement also identified the territories of kuwait as two different regions, demarcated in red and green on a map annexed to the convention. the red line, as it is commonly referred to, demarcated the region in which the sheikh was to have “complete administrative autonomy.” this region was formed by “a semicircle with the town of kuwayt in the center, the khawr al-zubayr at the northern extremity and al-qurrayin at the southern extremity” (article 5). this also included the surrounding islands of warba and bubiyan, which were major bargaining points for the british who viewed the ottoman military posts on the islands as a threat.
