Hai every one....this is the information I got from a history book....
The most famous among the chauhan rulers was Prithivi Raj Chauhan who ascended the throne at the young age of 11 or in about 1177.It is assured that he took the reigns of the administration in his hands at the age of 16 and immediately commenced a Vigorous policy of expansion at he cost of smaller states in Rajasthan.
The most famous expedition was however was the one aganist the Chaudelas of Khajuraho and Mahoba.As we have seen earlier the Chaudelas are the most poweful state in the region and which had a history of resistance against Ghazuavids.The fight in which the famous warriors Alah and Uday died fighting to save Mahoba.It has been immortalised in the Hindu epics,Prithviraj Raso and Alah Khanda.Since these were written later,the historical veracity of the account is doubted by the historians.However we can conclude that Prithvi gained a significant victory against the Chaudelas.Though he didnot acquire additional territories,he came home after acquiring considerable booty.
Between 1182 and 1187 Prithvi turned his attention towards his ancient rivals,the Chalukyas of Gujarat.The struggle was long drawn out and it seems the Gujarat ruler Bhima-2 who had earlier beaten off an invasion by the Ghuvid ruler,Muizuddin defeated Prithviraj also.This forced Prithviraj to turn his attention towards the Ganga Valley and Punjab.According to tradition there was a long drawn out tussel between him and Gahadvalas of Kannouj who had most extensive kingdom in the area.
The cause of this conflict is supposed to be Prithviraj's abduction of Sanyogita the beautiful daughter of the ruler Jaichand at her swayamvara and Jaichand's subsequent defeat in the battel.While the historians doubtful of the veracity of this story in the absence of any contemporary the rivalry between the Chauhans and Gahadvalas for the control over Delhi and the Upper Ganga was well known and may account for the subsequent attitude of Gahadvalas.
The point to note is that leading expeditions against all the neighbours Prithviraj has isolated himself politically.This cost him dear when he had to face the Turkish arrivals of Muiziddin Muhammed Ghor a few years later.
Muizuddin mohammed Ghor ascended the throne at Ghaza in 1773.His first expedition against India was lauched in1175 when he attacked and captured Multan which was under the control of Karavatis who were spread on the borders of India and Iran and whose religious ideas formed a half way house between Islam and Buddhism.The following year Muizuddin captured Uchch.In 1178-1179,he marched through Multan and Uchch to Neharwala in Gujarat.However the Gujarat ruler inflicted a crushing defeat to Muizuddin near Mount Abu....(Bhima-2)We are told that the Chalukyas had requested Prithviraj to help.Consediring both Ghoris and Cahlukyas to be the enimies of the Chauhans......ministers of Prithviraj declined to help.Since Prithviraj was barely small at that time he can hardly blamed for the decision.
After the failure of his Gujarat expedition Mauzuddin changed his whole plan of operations.Conquring Peshwar from the Ghazuavids in 1179-1180,he marched on Lahore in1181.The Ghazuavid ruler,Khusrau Malik surrendered.He was allowed to rule at Lahore while Muizuddin continuously expanded his control over Punjab,including Sailkot and also contributed for the consodilation of his control over Sindh upto the coast.Finally in 1186,Muizuddin removed the Ghazuavid ruler who was sent to prison in a fort and was put to death a couple of years later.The stage was not set for the conflict between the Ghoris and the Rajput rulers of North India.....
I got this information when I was referring one history book.We have to note
1. that Bhima 2 is not Bhimdev..
2.Prithvi took reigns at the age of 16(according to this).The one who took care of Ajmer and it's administration and also protected Prithvi upto 16 from other rulers who want to take over Ajmer,was none other than Dushyant Kaka......the Main Minister to Someshwar.(I thinkyou people remember him.My sir told me that Dushyant was not dead in the war between Someshwar and Bheemdev.Kamalavathi gave the duty of Prithi and his sister to Dushyant who is very loyal to Chauhans and entered the fire...Sati.)
Guys....It was really a tough job...readinf book writing the information in the book and again typing........please do comment and any mistakes please forgive me.
