Guess as how Lahore got its name. mmmm Lahoo? or Lopor? No idea! Lemme give you some historical data (from some references) so as to help you in getting something out of it.
Almost all history scholars agree on the point that the foundation of Lahore was laid by Raam Chandar Ji’s son Lahoo but Sheikh Ahmad Ranjani does not agree upon it. Sheikh Sb state that it were the successors of Pandoo’n; namely some Raja Prechat who had laid Lahore’s foundation and so has the name of Prechat Puri been put up.
Accoprding to ancient narrations, Lahore was called as Lopor, (winner of second guess CHEERS), however in the Rajput’s books, it is named as Lokot, which means Loho Fort. This pretty much provides a proof that the real founder was the Raam’s son LoyaLoh. Apart from all this contradictory, Lahore gained real fame when the Mughal Emperorship started reigning especially during the rule of King Babar, adding more hsitorical value to the city with architectures worth more for a discussion than the name itself. (And I must say Raza is helping us in this way).
