Input: Article: In the late 1960s, the term heavy metal was used interchangeably with hard rock, but gradually began to be used to describe music played with even more volume and intensity. While hard rock maintained a bluesy rock and roll identity, including some swing in the back beat and riffs that tended to outline chord progressions in their hooks, heavy metal's riffs often functioned as stand-alone melodies and had no swing in them. Heavy metal took on "darker" characteristics after Black Sabbath's breakthrough at the beginning of the 1970s. In the 1980s it developed a number of subgenres, often termed extreme metal, some of which were influenced by hardcore punk, and which further differentiated the two styles. Despite this differentiation, hard rock and heavy metal have existed side by side, with bands frequently standing on the boundary of, or crossing between, the genres.

Now answer this question: Hard rock is differentiated from heavy metal by containing more of an influence of what genre?

Output: bluesy

Input: Article: As a result of the three Carnatic Wars, the British East India Company gained exclusive control over the entire Carnatic region of India. The Company soon expanded its territories around its bases in Bombay and Madras; the Anglo-Mysore Wars (1766–1799) and later the Anglo-Maratha Wars (1772–1818) led to control of the vast regions of India. Ahom Kingdom of North-east India first fell to Burmese invasion and then to British after Treaty of Yandabo in 1826. Punjab, North-West Frontier Province, and Kashmir were annexed after the Second Anglo-Sikh War in 1849; however, Kashmir was immediately sold under the Treaty of Amritsar to the Dogra Dynasty of Jammu and thereby became a princely state. The border dispute between Nepal and British India, which sharpened after 1801, had caused the Anglo-Nepalese War of 1814–16 and brought the defeated Gurkhas under British influence. In 1854, Berar was annexed, and the state of Oudh was added two years later.

Now answer this question: After the sale of Kashmir, what did the area become?

Output: princely state
