Explanation: Himachal Pradesh, a state in northern India, has a rich and diverse history that spans several centuries. The region has been known by various names throughout its history, reflecting the influence of different dynasties and cultural movements. One of the most significant historical names associated with a part of the region is Kullu valley.
Kullu valley, located in the western part of Himachal Pradesh, is a picturesque region that has been inhabited since ancient times. The valley has been an important center for trade, culture, and religion. Historically, the Kullu valley was a part of the larger region that now constitutes Himachal Pradesh. The name "Kullu" itself is derived from the ancient Sanskrit word "Kulant," which means "end of the habitable world," reflecting the valley's remote and isolated location.
The Kullu valley has been mentioned in various ancient texts and inscriptions, indicating its significance in the region's history. It was a part of the Kullu Kingdom, which was ruled by the Katoch dynasty, one of the oldest ruling dynasties in India. The valley was also influenced by the Gurjara-Pratihara dynasty, the Chamba Kingdom, and the Mughal Empire, among others.
It is important to note that while Kullu valley is an ancient name for a part of Himachal Pradesh, it does not represent the entire state. The state of Himachal Pradesh was formed in 1966, and its boundaries encompass several historical regions, including Kullu valley, Shimla, Kangra, and others.
The other options provided in the question are incorrect because they refer to historical names of regions in different parts of India. Bombay (now Mumbai) was the old name for a city in western India, Madras Patnam (now Chennai) was the old name for a city in southern India, and Gurjaradesa was a historical region in central and western India. These names are not associated with Himachal Pradesh.
In conclusion, the old name for a part of the region that now constitutes Himachal Pradesh is Kullu valley, reflecting the historical and cultural significance of this area. Understanding the historical context of Himachal Pradesh helps in appreciating the rich cultural heritage and the diverse influences that have shaped the region over the centuries.
