English: Note: This is the standard "textbook" map of the Maurya Empire. Historians are now arguing that the Maurya Empire did not include large parts of India, which were controlled by autonomous tribes. For such a map, see File:Maurya Empire, c.250 BCE.png.

Notes:

• Sri Lanka and the southernmost parts of India (modern Tamil Nadu and Kerala) remained independent, despite the diplomacy and cultural influence of their larger neighbor to the north (Schwartzberg 1992, p. 18; Kulke & Rothermund 2004, p. 68).
• The account of Strabo indicates that the western-most territory of the empire extended from the southeastern Hindu Kush, through the region of Kandahar, to coastal Baluchistan south of that (Raychaudhuri & Mukherjee 1996, p. 594).
• The claim that Aria/Herat was one of the provinces (alongside Arachosia, Gedrosia, and Paropamisadae) ceded by Seleucus to Chandragupta Maurya is often repeated, but Aria (modern Herat) "has been wrongly included in the list of ceded satrapies by some scholars [...] on the basis of wrong assessments of the passage of Strabo [...] and a statement by Pliny." (Raychaudhuri & Mukherjee 1996, p. 594). Seleucus "must [...] have held Aria", and furthermore, his "son Antiochos was active there fifteen years later." (Grainger 2014, p. 109).
• Schwartzberg (p. 18) speculates about the Buddhist culture and Kharosthi inscriptions/manuscripts found in Khotan, but these texts from Khotan, Turfan, and Tajikstan have all been shown to be later than the 1st century BCE (Puri, p. 185).
