Abstract	This paper argues that the Mauryan empire could not have been held together under a single authority without a system for acquiring, moving and verifying information, and that this proposition — which no surviving document states in so many words — can be established by correlating four independent bodies of evidence: the Aśokan inscriptions, the Arthaśāstra, the Greek testimony as transmitted by later authors, and the Buddhist literary tradition. It sets out the Arthaśāstra's architecture of secret activity — the recruitment of agents "from all groups," their deployment "in two basic groups (saṃstha and saṃchār)," their dispersal "for early detection in one's own country, an enemy country, a friendly country, and a neutral country," and the establishment of "a permanent wing for collection and analysis of latest information" with agents stationed in the courts of "the enemy, the ally, the Middle, and the Neutral kings to spy on the kings as well as their eighteen types of high officials" (Sumaryani, 2021)(Sihag, 2017) — together with its repertoire of covert action: the assassination of enemy officers, the engineering of quarrels among them, and disinformation designed to demoralize enemy troops (Boesche, 2003)(Bhattacharya & Saikia, 2020). It then reconstructs the communications substrate on which any such system must run: the Uttarāpatha and Dakṣiṇāpatha routes and the royal road from Taxila to Pataliputra with pillars marking distances and byroads every ten stadia (Dwivedi, 2021)(Laizet, 2021), the supervised ferry and seafaring traffic and the navarch who hired vessels to travellers and sea traders (Dwivedi, 2021)(Laizet, 2021), the ports at river estuaries from Barygaza to Tamralipti (Dwivedi, 2021)(Arunachalam, 2025), and the fourfold army with its officers of horses, elephants, chariots and infantry (Reden, 2019)(Dwivedi, 2021). It examines three episodes as corroborating instances: the revolt at Taxila, which Aśoka handled as a prince and which the scholarship treats as the experience that determined his attempt on the throne (Thapar, 2012); the capture of the throne at Pataliputra, where "Aśoka was not the crown prince, and... there was a struggle among the princes for the throne" (Thapar, 2012), resolved when he "raised an army against, and possibly killed, his brother Sumana-Susima" (Testa, 2014); and the conquest of Kalinga, where Rock Edict XIII records the outcome and the remorse but not the method (Chassanite, 2015)(Bartles-Smith et al., 2020), and where the inference of prior intelligence and covert preparation is offered as a hypothesis rather than a finding. The paper's central structural argument is supported by a recent formal estimation of Mauryan institutions, which recovers the monitoring-cost parameter from GIS-derived travel times across the Gangetic plain and dendrochronological monsoon variation, and finds that an average oversight distance of approximately 850 km combined with output volatility of σθ ≈ 0.31 generated the empire's distinctive institutional choices endogenously — a fixed one-sixth tax share and an 800:1 wage ratio between senior councilors and junior clerks — and that replacing Mauryan direct administration with Roman-style tax farming would have shortened imperial survival by roughly 45 years (Kamat, 2025). The paper concludes that the importance of the Mauryan information system lies in its design rather than its surviving outputs, and that the appropriate description of the evidence is a reporting and inspection system of documented architecture operating within an information environment that recent scholarship shows to have been severely constrained.
