(a) , pp. 68–70, "It is known from internal evidence that the Vedic texts were orally composed in northern India, at first in the Greater Punjab and later on also in more eastern areas, including northern Bihar, between ca. 1500 BCE and ca. 500–400 BCE. The oldest text, the Rgveda, must have been more or less contemporary with the Mitanni texts of northern Syria/Iraq (1450–1350 BCE); [...] The Vedic texts were orally composed and transmitted, without the use of script, in an unbroken line of transmission from teacher to student that was formalised early on. This ensured an impeccable textual transmission superior to the classical texts of other cultures; it is in fact something of a tape-recording of ca. 1500–500 BCE. Not just the actual words, but even the long-lost musical (tonal) accent (as in old Greek or in Japanese) has been preserved up to the present. [...] The RV text was composed before the introduction and massive use of iron, that is before ca. 1200–1000 BCE.";(b) , pp. xviii, 10, "A Chronology of Hinduism: ca. 1500–1000 BCE Rig Veda; ca. 1200–900 BCE Yajur Veda, Sama Veda and Atharva Veda [...] Hindu texts began with the Rig Veda ('Knowledge of Verses'), composed in northwest India around 1500 BCE; the first of the three Vedas, it is the earliest extant text composed in Sanskrit, the language of ancient India.";(c) , p. 19, "In Punjab, a dry region with grasslands watered by five rivers (hence 'panch' and 'ab') draining the western Himalayas, one prehistoric culture left no material remains, but some of its ritual texts were preserved orally over the millennia. The culture is called Aryan, and evidence in its texts indicates that it spread slowly south-east, following the course of the Yamuna and Ganga Rivers. Its elite called itself Arya (pure) and distinguished themselves sharply from others. Aryans led kin groups organized as nomadic horse-herding tribes. Their ritual texts are called Vedas, composed in Sanskrit. is recorded only in hymns that were part of Vedic rituals to Aryan gods. To be Aryan apparently meant to belong to the elite among pastoral tribes. Texts that record Aryan culture are not precisely datable, but they seem to begin around 1200 BCE with four collections of Vedic hymns (Rg, Sama, Yajur, and Artharva).";(d) , pp. 14–15, "Although the collapse of the Indus valley civilization is no longer believed to have been due to an 'Aryan invasion' it is widely thought that, at roughly the same time, or perhaps a few centuries later, new Indo-Aryan-speaking people and influences began to enter the subcontinent from the north-west. Detailed evidence is lacking. Nevertheless, a predecessor of the language that would eventually be called Sanskrit was probably introduced into the north-west sometime between 3,900 and 3,000 years ago. This language was related to one then spoken in eastern Iran; and both of these languages belonged to the Indo-European language family. [...] It seems likely that various small-scale migrations were involved in the gradual introduction of the predecessor language and associated cultural characteristics. However, there may not have been a tight relationship between movements of people on the one hand, and changes in language and culture on the other. Moreover, the process whereby a dynamic new force gradually arose—a people with a distinct ideology who eventually seem to have referred to themselves as 'Arya'—was certainly two-way. That is, it involved a blending of new features which came from outside with other features—probably including some surviving Harappan influences—that were already present. Anyhow, it would be quite a few centuries before Sanskrit was written down. And the hymns and stories of the Arya people—especially the Vedas and the later Mahabharata and Ramayana epics—are poor guides as to historical events. Of course, the emerging Arya were to have a huge impact on the history of the subcontinent. Nevertheless, little is known about their early presence."; (e) , pp. 46–, "The expansion of Aryan culture is supposed to have begun around 1500 BCE. It should not be thought that this Aryan emergence (though it implies some migration) necessarily meant either a sudden invasion of new peoples, or a complete break with earlier traditions. It comprises a set of cultural ideas and practices, upheld by a Sanskrit-speaking elite, or Aryans. The features of this society are recorded in the Vedas.", India has been a federal republic since 1950, governed through a democratic parliamentary system.
