Balarama is a Hindu god and the elder brother of Krishna. He is particularly significant in the Jagannath tradition, as one of the triad deities. He is also known as Haladhara, Halayudha, Baladeva, Balabhadra and Sankarshana.
The first two epithets refer to his strength, and the next two associate him with Hala from his strong associations with farming and farmers, as the deity who used farm equipment as weapons when needed.
Balarama is sometimes described as incarnation of Shesha, the serpent associated with the god Vishnu; Krishna is regarded as an incarnation of Vishnu. Some traditions regard him as one of 10 principle avatars of Vishnu himself. (source-wikipedia)
