Administrative set-up
During his reign, Chiratadatta was the governor of Pundravardhana Bhukti. A prince, Ghatotkachaqupta was the governor of Eran and a third governor (or feudatory), Bandhuvarma was the ruler of Dashapura. The Karmadande inscription (436 CE) mentions Prithivishena, who was initially mantrin andkumaramatya (minister) of Kumaragupta I, but later became his mahabaladhikrita (general).
Iron pillarMade up of 98% wrought iron of impure quality, it is 23 feet, 8 inches high and has a diameter of 16 inches. The pillar is a testament to the high level of skill achieved by ancient Indian iron smiths in the extraction and processing of iron. It has attracted the attention of archaeologists and metallurgists as it has withstood corrosion for the last 1600 years, despite harsh weather.
Kumaragupta erected an iron pillar, today visible at the Qutb complex. The iron pillar is one of the world's foremost metallurgical curiosities. The pillar was originally located in the temple of Muttra, with the deity Garuda at the top. It is the only piece of the Hindu temple remaining, which stood there before being destroyed by Qutb-ud-din Aybak to build the Qutub Minar and Quwwat-ul-Islam mosque. Qutub built around it when he constructed the mosque.
.The Junagadh rock inscription of Skandagupta mentionsSuccession after Kumaragupta I
The modern scholars are divided in opinion regarding the immediate successor of Kumaragupta I. While some scholars opine that he was succeeded by his son Skandagupta, other scholars contend that he was succeeded by his other son, Purugupta. Some scholars even think that both Skandagupta and Purugupta are the same person.
…whom the goddess of fortune and splendour of her own accord selected as her husband, having in succession (and) with judgment skillfully taken into consideration and thought over all the causes of virtues and faults, (and) having discarded all (the other) sons of kings (as not coming up to her standard).
The full significance of this passage is obscure. It is, however, certain that the superior ability and prowess of Skandagupta in a time of crisis led to his choice as ruler in preference to other possible claimants after the death of Kumara Gupta I and proud of his successes against the barbarians, Skandagupta assumed the title of Vikramaditya.
The continuous attacks of the Huns weakened the Gupta empire. Skandagupta died in 467 CE. After his death, the Gupta empire began to decline.
Dated inscriptions
An inscription on a figure of a yaksha from Mathura in the reign of Kumaragupta has been dated to 432 CE, and a pedestal (with no king's name on it - but presumably from Kumaragupta's reign - has been dated to 442 CE.[5] The Bilsad inscription is the oldest record of his reign and it dates to Gupta year 96, which corresponds to 415 CE.
Decline of the Gupta Empire
Inscriptions prove that the Gupta sovereignty was acknowledged in the Jabbalpur region in the Narmada valley as late as AD 528, and in North Bengal till AD 543–544. Kumaragupta II is believed to have been ruling in AD 473–474, Buddhagupta from AD 476–495, Vainyagupta in AD 508 and Bhanugupta in AD 510–511. The Gupta empire became to disintegrate and till the middle of the sixth century AD, they had merely became petty chiefs.
The last known date of his reign occurs on an inscription on one of his silver coins, corresponding to 445 CE.
