In 185 BCE he assassinated the last Mauryan Emperor - Brihadratha Maurya, during an army review, and made himself as an emperor.Pushyamitra is recorded to have performed numerous Ashvamedha campaigns to legitimize his right to rule. Inscriptions of the Shungas have been found as far as the Ayodhya (the Dhanadeva-Ayodhya inscription), and the Divyavadana mentions that his empire stretched as far as Sakala (Sialkot) in the Punjab region in the northwest. The Greeks and all other rivals having been disposed of in due course, Pushyamitra was justified in his claim to reign as the paramount power of North India and Straightway proceeded to announce his success by a magnificent celebration of the Ashwamedha sacrifice at his capital. Later Greeks were attacked by Shaka's and this was the end of Greeks in India.

#3 The Attack of Shakas & Kushanas in India And The Great Emperor Vikramaditya - Gupta Empire, (240 CE - 540 CE)

As soon as the Kushans heard the news about Smaudragupta's attack on Gandhar they became refuge to the Gupta emperor and this was the end of Kushina's rule in India.

Indian patriots like Tatya Tope, Rani Lakshmibai, Chandrashekhar Azad, Mahatma Gandhi, Swatantryaveer Savarkar, Lokmanya Tilak, Netaji Subhashchandra Bose, and many more resisted this British rule and India once again became the Independent Country.

#Conclusion

For 6 times in the past 2500 years, India was tried to be invaded by the foreign attacks and India is the only place on Earth which retreated every single foreign attack and never changed itself according to foreign wishes! The past before Alexander and Chandragupta Maurya still exists in great literature written by indian writers. There will not be a long time when India's true history will be uncovered and the world will know it. Indians always transferred the knowledge by shruti (Listening) and smriti (Remembering) but that doesn't make the knowledge questionable and falsy.
