hey i' doing GCSE history and i have to do an esasy on the privy council and parliament during elizabeth the I reign. I was wondering what was the name's of the most important and privy councillors and what did they do ?

Is this thread any use to you?

As there doesn't seem to be much readily available, here are a few pointers.

Some names of privy councillors, for you to look up on Google or wherever:
William Cecil, later Lord Burghley
Robert Cecil, William's son
Robert Dudley, Earl of Leicester
Robert Devereux, Earl of Essex

The Privy Council was made up of a mixture of important noblemen (e.g. Earl of Leicester) and men who had risen to power because of their ability and loyalty (e.g William Cecil). The Council gave advice to Queen Elizabeth and then carried out her decisions. Most of the work was done by a small 'inner circle' of professional advisers led, for much of her reign, by William Cecil. Examples of areas where the Council gave advice are: foreign policy (e.g. relations with Spain), the question of Elizabeth's marriage and religious policy. Councillors also carried out administrative tasks such as: overseeing finances, meeting ambassadors, overseeing parliamentary business and drafting correspondence.

I hope that this helps.
