Oliver Cromwell
Oliver Cromwell overthrew the English government and King Charles I. He established the Commonwealth of England and ruled as Lord Protector until his death in 1658.
Charles I
Charles the first . The above does not answer the question. Charles I was executed in 1649 and England became a 'Commonwealth' under Oliver Cromwell. In 1660, Charles' son was invited back to England to become Charles II, England having become tired of the Commonwealth.
Sometime after the collapse of the Commonwealth of England and the removals of the Protectorate, Charles II Stuart was invited to take back the Throne.
A Republic? Under Cromwell,between the reigns of Charles 1 and Charles 11,England was described as being a Commonwealth.
No ideas were introduced into England by the Commonwealth. The Commonwealth was established from the British Empire with the Queen being the head. England, being the main member state of U.K, therefore had nothing introduced into it from the Commonwealth opposed to England introducing ideas into Commonwealth member countries. So I'm not sure if this is what you meant, but I think your question should be "What two ideas did England introduce into the Commonwealth?" and in that case I would say that there are a lot of ideas that were introduced, too many to list without having more specific details on what type of ideas you want listing.
