Dynasty After War

1. Kaurava Dynasty was Continued by Suradha Son of Jayadradha Son in Law of Dhritarashtra
2. Pandav Dynasty was Continued by Parikṣit Son of Abhimanyu Son of Arjuna

Both of them were revived after death by krishna

Dushala to Arjun - We need peace. Let us end this strife forever. No more never this war.
