By 1589, Elizabeth has made a favourite of Essex and falls in love with him. She is openly outraged when he takes part in an English military expedition to Lisbon against her wishes, but she forgives him in spite of his failure to take the city from the Spanish. She grants him 10 percent of a tax on sweet wines and a seat on the Privy Council, of which Lord Burghley's son Robert Cecil was also recently made a member. Essex and Cecil develop a rivalry, as illustrated by the affair of Elizabeth's physician Dr. Lopez, who is hanged based on evidence brought forth by Essex of his participation in a Spanish plot against Elizabeth, evidence proven questionable after the fact by Cecil.
