It is unfortunate that Jaichand is used as a 'slur' for a traitor. He was the one who built the golden spired temple at Ayodhya for Rama. Under his patronage, the last Mahakavya of Sanskrit was written. He lost his life defending our motherland till his last breath against Ghori.
Jaichand has been demonized because a bardic tale written 400 years after his death vilified him. There is also a bardic tale prevalent in Gujarat which vilifies the great Maharana Pratap. If we keep on canceling people based on later-day bardic tales, we won't have anyone left. Jaichand was a martyr who sacrificed his life on the battlefield protecting the most hallowed Hindu cities of Ayodhya and Varanasi.
Jayachandra was Born to Gahadawala King Vijaychandra and Queen Chandralekha. He was the Grandson of Famed Govindachandra of Kannauj Who levied reverse Jaziya on Moslems. He was declared Crown Prince (Yuvaraja) in 1168 and Was Crowned as King on the 21st of June 1170. He Ruled over One of The Richest Lands in India at That Time. Muslim Historians Declare him as “The king of Benares was the Greatest King In India, and Possessed the largest Territory”. Indologist A. Fuhrer Found an Inscription in Ayodhya Dated to 1184AD, which Praises King Jayachandra Of Kannauj who Erected a Vaishnava (Ram) Temple at Treta-ke-Thakur In Ayodhya. The Most Popular Source which Adds to this myth of Jayachandra Being a Traitor is Prithviraj Raso of ChandBardai, Which is Grossly Inaccurate. This theory has been Rejected by All Eminent Historians.
After the Defeat of Prithviraj in 1192 AD, Mlecchas Turned their Attention towards the Rich kingdom of Kannauj. A Brutal Battle took Place in 1194 AD, where, Unfortunately, Jaichandra was struck by An Arrow and killed. Later, His Treasury was Looted, and 1000 Temples were Razed. Jayachandra Ruled over an Extensive territory Including Most of the Present-Day UP, in South East Upto River son, in East Nearly Upto Patna and Gaya.
