Dunno...Different historians have different accounts on this...Some say that it WAS cuz of Sanyo...Cuz PRC was SOOOOOOOO BESOTTEDDD & IN LOVEEE with her that he had started to neglect the state affairs of Ajmer & Delhi....Other historians say that it was cuz of PRC'S short-sightedness & his refusal to include the Muslims in the congregaton that he & a few other kings had started( in this,Jaichand was called..& he did come...BUT HE LEFT THE MINUTE HE CAME TO KNOW THAT PRC WAS THERE 😡 )...Historians,also say that WHAT-EVER Jaichand did was NOT to increase his kingdoms & all...BUT TO AVENGE THE "INSULT"THAT HE HAD RECEIVED WHEN PRC & SANYO ELOPED IN FRONT OF HIS EYES 😡 😡 😡 ....I DON'T THINKK that Sanyo would have accompanied PRC on his battles...That used to happen with the Mughals..& THEN ALSO,ONLY WITH SHAH JAHAN & MUMTAZ...Shah jahan apparently,coudn't EVEN LIVE witout Mumtaz during his war campaigns..SO he,her & their family used to ALL travel together....DON'T THINK THAT IS POSSIBLE...PRC Raso,despite being a VERYYYY GOOD source on PRC 😛 ...HAS STILL QUITE A FEW ERRORS..SO,I DO BELIEVE IT A LOTTT....BUT NOT,FULLYY..Chand WAS at the end of the day,PRC'S court poet...Usne kafi kucch,drama quotient ke liye daala hain 😃
