causes of the Essex Rebellion (1601)?

• War and Violence:

  > Ireland: In 1598 Elizabeth asked Essex to defeat a rebellion in Ireland. He was reluctant to go at first, fearing that Cecil would become more powerful while he was away, but eventually agreed. He failed to defeat the Irish rebel leader, made a truce with him, and even knighted some of his army, all which the Queen had forbidden him to do.
• Government:

  > Patronage: While Essex was away fighting, the Queen promoted Cecil. Sparked by jealousy, on his return to Court, Essex burst into the Queen's bedchamber before she was wigged and gowned.

  For Elizabeth, this was the final straw. Charges were made which he had to listen to on his knees and he was then placed under house arrest.
• Economic Resources:

  > Monopoly: To make matters worse, Elizabeth did not renew his sweet wine monopoly (when the queen gave him the monopoly of sweet wine in England he accumulated great wealth as it meant by law anyone who wished to bring in sweet wine from abroad would have to pay him a tax). Essex faced financial ruin.
