When Krishna killed his uncle Kamsa in Mathura, Jarasandha become enraged because of Krishna and the entire Yadava clan on seeing his two daughters being widowed. So, Jarasandha attacked Mathura and the Yadavas 17 times. Once his army included the Panchalas and the Kurus among other kings of India. While Krishna and the Yadavas survived the attacks, sensing danger Krishna relocated his capital city to Dwaraka.
Dwaraka was an island and it was not possible for anyone to attack it at all.
Krishna began a campaign to diminish the power of Jarasandha, one by one eliminating his powerful allies like Kalyavana, Naraksura, Hansha, Dimbaka. Jarasandha participated in the Swayamvara of Draupadi, and after being unable to lift the bow, left the place.
