It was money but there was something else also and along with this we will also see the political importance as well as the administrative and the cultural importance of this Greco-Roman and Indian conference that we are going to see but before we get on to that a quick info for all of you guys if you are preparing for TSPSC group 1, TSPSC group 2, this is the opportunity for you right now we are running the live batches and you can call on the numbers given below to inquire for more, we are also giving you a very huge discount right now even if you are preparing for UPSC, CSE 2026, 2027 this is the opportunity for you straight over 50% discount and you can call on the numbers given below for more infos. So let's get started with our class so in the last class we studied about the Persian Empire and in Persian Empire we studied that Xerxes possibly the one after Cyrus the Great and Darius he was the one who took help of Indians into the military of the Persian Empire and had fight with the Greeks but he was defeated by the Greeks and you know after that we saw that there was downfall of this Persian Empire and Alexander the Great who was firstly the Prince of Macedonia okay he belonged to Macedonia so he being the Prince of Macedonia later on he will become the King of Macedonia somewhere around 336 BC and he will defeat Darius III yes Darius III of Persian Empire yes will be defeated by Alexander the Great and he will unite the full Greece okay and he will have a very big empire by the year 334 BC you can say that he will unite Greece and he will come to know about India he has heard a lot about India from the Greek philosophers like Herodotus and others also that it's a very wealthy space if you remember while the Persian Empire we studied that one of the satrapy that is the Hindus satrapy was giving one third of the revenue of what the total revenue was collected from the Persian Empire in Asia so these stories were always very famous there and there was one more reason the reason was the ambition of Alexander the Great Alexander the Great or Sikandar Mahan that's what they call him wanted to conquer full world and India at that time was told to be the eastern boundary of the world so he had started from the west and if he can win the eastern boundary that means he has won the complete world and that is what was the ambition that brought Alexander the Great towards India and when he will enter the Khyber Passes okay he when he will cross the Hindukush mountain there he will have fierce battle for almost 10 months with the tribal people living over there so let's get started with the slides also let's see a bit so Alexander's ambitions was in a way related to that the legends say that India has a lot of wealth and desire to reach to the end of the world this is what we have talked about that India was considered to be the eastern boundary so Alexander came here and when he will enter here this part the northwestern Indian regions if you remember the last class Persians had already conquered Gandhar, Punjab and Sindh and they were already the part of the Persian archimede empire so this was the next target after Persia has fall the this was the next target of Alexander the Great so the preparation and initial advances that he will do will be Alexander cross the Hindukush mountains from Bactria into the Indus valley somewhere around 327 BC and he subdued various tribes in present-day Afghanistan and Pakistan some of the notable tribes that you can see here stopped him for almost 10 months and one very famous fierce resistance was encountered especially from the Asa Kenoi whose queen Cleophis led the defenses of Massaga now these names if you are finding that it's not Indian name it's because these are from the sources of the Greek philosophers that's why you're finding these names in that way so one thing we can understand that he got into fierce battle with them and for almost 10 months he had to you know held the resistance of the Indian tribes and after that he will come towards Tachesila. Tachesila at that time will be ruled by Ambhi whom they used to call as Amphis so Ambhi will surrender directly to Alexander and he will provide troops and support also to the surrender to Alexander the Great and Alexander the Great then will move towards Hydepsis what is Hydepsis basically Jhelum was known as Hydepsis by the Greeks there at that time so there will be this battle of Hydepsis between whom it will be between Porus okay or the Porva and Alexander the Great at the banks of Hydepsis or the Jhelum river and it will be fought in the plains of Kari please note this also down it might be important for you in the exams so Porus's army will include infantry cavalry chariots and war elephants Porus's army will be outnumbered they will be outnumbering Alexander's army but Alexander's tactical moves will leave him to victory now here there is one more thing that you should note down in the Greek books or the Greek evidences whatever we find we find that Alexander defeated Porus and reinstated Porus but in some of the books we find that according to the Indian history that Porus was not defeated by Alexander rather Alexander was defeated and those were the reasons why he had to go back but nonetheless according to the Greek historians it was Alexander who defeated Porus and reinstated Porus again because of his bravery but after winning the war now he has his eyes on Magadan empire yes at that time the most powerful you can say the territory at that time was Magada and there ruled Nandas and on Nandas also which Nanda was basically there it was Dhananand at that time okay the very famous Dhananand who insulted Chanakya and Kaudilya and who will be overthrown by Chandragupta Maurya but at this point of time they wanted to attack Alexander and his army wanted to attack Magadan empire but there will be a mutiny mutiny in the true and why this mutiny will happen there are few reasons for this mutiny to happen first and foremost they are out for 10 years almost 10 years they are out so they are war weary they are now fed up with the war that's one thing second reason if you see they are facing a lot of heat in India the scorching heat they are not apt or adaptable enough to this sort of climate okay so that is something which is not in favor of the troops number three if you see their disease in India they are not finding it easy because again of the climate change and all those things it's not easy for them to stay here that's also a problem with this they are also homesick as I've already said you from 10 years they are away from their home so this is also a reason and lastly most important reason was the Magadan army yes the Magadan army this was a very big reason because it was said at that time Magadan has very huge army whether it's the elephants whether it's the horses whether it's the persons on foot the military on foot everywhere it was a very huge army and there's all the reasons combined together for this troop mutiny and it forced Alexander the great to return back okay and while he will be returning back there will be small battles that he will be facing with the tribes who had the fight when he was coming towards India he will again face all those battles there and then you will also see that he will in the Gathrosian desert he will suffer heavy losses from the harsh conditions also and the time in 323 BC when they will reach babylon by that time Alexander the great will be very sick and unfortunately he will die and his wish to conquer the world will remain as a wish only okay let's see about the administration and governance at that time the satrapies the provinces satrapies are the provinces Alexander left satraps means the governors and the satrapies means the provinces and military commanders to rule conquered territories when he was returning back he will give some of the areas conquered to Porus some of the areas conquered to Andhi and the other areas he will appoint his own governor and if you remember they will be one of his governor in the northwest India his name will be Seleucus Nicator and this Seleucus Nicator guys will form Seleucid empire this will also be there we will see this in the next class Greek administrative control was brief after Alexander's death in 323 BC local powers will quickly reassert themselves and Mauryan empire will also absorb whatever the reasons were conquered by Alexander the great opening of the land routes the invasion established four distinct routes between India and the west three by land and one by sea this is what was done because of this Alexander's invasion these routes paved the way for Greek merchants and craftsmen to establish contact with India so because of that invasion the trades have also boomed Alexander's conquest helped connect India to ease early silk road trade networks felicitating the movement of goods between east and west and also the trade routes Hellenistic culture hybridized with Iranian and Iranian traditions though there was already this Persian traditions and Indian tradition and now a new confluence will come of the Greek culture and Greek traditions as well one thing to note down the naval expedition led by Nearchus who was Alexander's admiral explored the sea route from the Indus delta to the Persian Gulf so please remember Nearchus okay and his knowledge of maritime routes that would later become vital for Indo-Mediterranean trade while we are talking about the economic exchange and commercial activities Greeks were introduced to Indian luxury items including precious stones, pearls, spices, textiles and exotic animals which became highly sought after in west and the invasion exposed Indians to Greek coinage system while Greeks became familiar with the punch mark coins of India this punch mark coins of India were the features of the Mahajanpadas please remember that okay so every Mahajanpada had their different punch mark coins this exchange influenced later Indo-Greek monetary system as well the monetary influence Greek monetary concepts influenced later Indian coinage particularly visible in the coins of Indo-Greek kingdoms and Kushanas and we'll also see this after the Alexander the Great particularly with the Seleucid Empire the trade and the culture Hellenistic culture this will increase in a way this you can see this is the empire of Alexander the Great of at that time and it contains the northwestern part of India okay so this is something to keep in mind and the cultural exchange that happened at that time let's see a bit about the Greco-Buddhist art or the Gandhara school the most notable cultural synthesis that happened emergence of Greco-Buddhist art especially in Gandhara region that is modern day Pakistan and Afghanistan this art form combined Greek artistic technique such as the realistic human anatomy drapery and facial expressions we are going to see this in the statues so that you understand it more nicely so if you see here you you see at the back there is a halo being created you see the hair if you're seeing it is very properly knitted if you see the cloth that is being used this rob is having drapes this drapery system all this was the feature of the Gandhara school which was the confluence of the Indian and Buddha was depicted in human form with Hellenistic features such as wavy hair and naturalistic body Greek motifs and styles including the use of marble and stone carving were integrated and the fusion influenced Buddhist art across Asia spreading to Central Asia as well if you see few of the features here if you see the hairstyle okay the very distinctive hairstyle if you see you see the nose pointed noses are made you see the body masculine body is presented here so all these things were very distinctive features here if you see the cloth okay this drapery that is done on the cloth so these are the very distinctive features that you see were present of the Gandhara school Greek architectural elements sensuous Indian temples and stupa designs visible in the use of columns capitals and decorative motifs inspired by the Hellenistic style if you see this pillar this is of Egypt this again is of Persia this the very famous Versailles thumb of Ashoka this is from India obviously and this you see of Greece column from the temple of Jews so this you can see had a confluence on each other and inspired each other with this traditions and religious and philosophical exchanges were also there Greek patronage helped Buddhism flourish and spread beyond India contributing to its transmission along the Silk Road Greek and Indian philosophical traditions influenced each other and we'll also see the exchange and both traditions contributed to the development of Indian intellectual thoughts the geek invasions of India catalyzed a rich cultural exchange that transformed Indian art religion philosophy and trade the fusion of geek and Indian tradition created enduring legacies visible in the Greco-Buddhist art and the spread of Buddhism which saved the cultural and intellectual history of the regions for centuries okay so let's see some of the question which one of the following rulers is associated with the Buddhist text Milinda Panu so the correct answer here is Menander I or Milinda this is what he was called you can pause here and see the explanation the next question the Indo-Greek coins are significant in Indian history because they had bilingual inscriptions yes Kharosti sometimes sometimes the Brahmi script and as well as Greek was used here okay let's see the next question which dynasty was ruling over North India at the time of Alexander's invasion which I it was I have told you very nicely Dhananand or the Nanda dynasty at that time was ruling what was the major cultural impact of the Indo-Greek rule in India development of Gandhara school of art is something which was the major impact and last but not the least we are having to see the statements relating to Menander I he was originally a king of Bactria yes he is the only Indo-Greco king widely mentioned in the Indian literature yes he was converted to Buddhism and his relics were enshrined in stupas this is something can be true or not okay but let's see Menander I was originally a king of Bactria as the most elevated Indo-Greek king in Indian sources and according to Buddhist tradition converted to Buddhism with his relics enshrined in stupas after his death so one two and three all are correct and you can be correct if you are
