The legendary Outlaw  Robin  Hood.

Hero of a series of English ballads ,some of which date from at least as early as the 14th century,
Robin was a rebel and many of the most striking tales about him and his companions robbing representatives of authority and giving the gains to the poor,

Their most frequent enemy was the Sheriff of Nottingham, a local agent of the central government, Other enemies included wealthy ecclesiastical landowners,
Robin treated women,the poor,and people of humble status with courtesy,

A good deal of the impetus for his revolt against authority stemmed from popular resentment over those laws of the forest that restricted hunting rights.
The early ballads, especially, reveal the cruelty that was an inescapable part of medieval life.

Numerous attempts have been made to prove that there was a historical Robin Hood,though references to the legend by medieval writers make it clear that the ballads were mainly the evidence for his existence.

The authentic Robin Hood ballads  were the poetic expression of popular aspirations in the north of England during turbulent times of baronial and agrarian discontent, The theme of the free but persecuted outlaw enjoying the forbidden hunting of the forest and outwitting the forces of law and order naturally appealed to the common people

Although many of the best-known Robin hood ballads are postmedieval, there is a core that can confidently attributed to the medieval period.

These are Robin Hood and the Monk
Robin hood and Guy of Gisborne
Robin Hood and the Potter
and the Lytyll Geste of Robin hood.
