Anyone please enlighten me about the "facts"mentioned here!!
Especially the one in red...Regarding Duryodhan 's gift to Karna,i agree with you..A person who was not even a crowned prince..How can he gift a kingdom!!!
As per Vyasa Karna and Duryodhan were childhood friends (Karna was taught by Drona until he desired to learn Brahmastra) and apparently he was also party to Duryodhan's plan to poison Bhim.
However most modern adaptions do not portray events in that fashion. In modern interpretations/adaptions Karna was outrightly rejected by Drona and met Duryodhan only on the day of the tournament.
