India (Frommer's, 4th Edition) - Keith Bain [21]
From the 6th century B.C., the Aryan states were themselves subject to invasions from the north, in a cycle of incursion and subsequent local adaptation that was to dominate much of India’s history. Even Alexander the Great, hearing of the wealth and fertility of the area, tried to invade, but his army apparently refused to cross the Indus River and instead made their way back to Macedonia. Other invaders (or settlers, depending on your preference) of Greek, Persian, and central Asian origin moved in, challenging some of the indigenous states, such as Shakas of western India and the Magadha state of the northeast. In time, all of these newcomers were absorbed into the local population. It was during this period that Siddhartha Gautama (Buddha) was born in latter-day Nepal; he later moved to India, where he sought—and found—enlightenment at Bodghaya, and starting teaching at Sarnath, just outside Varanasi.
The first large state to emerge in this region was under the Mauryan rulers (322–185 B.C.), who incorporated much of northern India, including the region west of the Indus; at its largest, it even reached south to Karnataka. The most famous of these rulers was Asoka, who converted to Buddhism after a particularly murderous episode of conquest pricked his conscience; he spread the Buddha’s teachings throughout northern India, particularly at Sarnath and Sanchi, where you can still view the stupas (commemorative cairns) he built. Asoka’s decrees, which were inscribed onto rock (literally), carved his reputation throughout the region, while his emblem of four back-to-back lion heads (which you can also view at Sarnath) has been adopted as the modern symbol of India.
Asoka’s empire barely survived his death in 232 B.C., however, and in the subsequent centuries local states rose and fell in the north with alacrity. The Gupta empire emerged from A.D. 319 to 540 under Sumadra Gupta, who conquered the small kingdoms of much of northern India and Bengal, while his son extended its range to the west. This loose confederacy was marked by a reinvigoration of Hinduism and the power of the Brahmins, which reduced the influence of Buddhism in the subcontinent (though it had taken strong root in Sri Lanka and Southeast Asia). But Hun invasions from the north in turn destroyed Gupta power, and northern India was again split into numerous small kingdoms.
It should be noted that the southern part of India remained unaffected by these developments. With the exception of Asoka’s Mauryan empire, none of the northern states extended their influence beyond the central plains, and South India developed its own economic systems, trading with Southeast Asia and across the western Indian Ocean as far afield as the Roman Empire. Dravidian kingdoms emerged, some of which established sizable empires such as the Pallava (A.D. 300–900) and Chola (A.D. 900–1300). Hinduism flourished, evident in the rich legacy of Dravidian temple architecture (notably
