1. About John Lilburne
Lilburne was a Parliamentary soldier in the Civil War, and a Puritan martyr.
In 1637, Lilburne met and proceeded to work with John Bastwick, a Puritan preacher who had just had his ears cut off for writing a pamphlet attacking the views of the William Laud.
In 1638 he was flogged through the streets of London for his work for the underground Puritan press, and was later arrested.
He was an unreserved radical, and often taunted Parliament with radical religious tracts.
Following the war, Lilburne complained about the intolerance of the Presbyterians and argued for freedom of speech for the Independents.
He was prosecuted multiple times for the spreading and publication of his radical ideas.

Lilburne called for a Levellers revolt when his proposed reforms were rejected by the NMA, but he was arrested and sent to the Tower of London. Cromwell later banished him from England
