The favourite can often not be easily distinguished from the successful royal administrator, who at the top of the tree certainly needed the favour of the monarch, but the term is generally used of those who first came into contact with the monarch through the social life of the court, rather than the business of politics or administration. Figures like William Cecil and Jean-Baptiste Colbert, whose accelerated rise through the administrative ranks owed much to their personal relations with the monarch, but who did not attempt to behave like grandees of the nobility, were also often successful. Elizabeth I had Cecil as Secretary of State and later Lord High Treasurer from the time she ascended the throne in 1558 until his death 40 years later. She had more colourful relationships with several courtiers; the most lasting and intimate one was with Robert Dudley, Earl of Leicester, who was also a leading politician. Only in her last decade was the position of the Cecils, father and son, challenged by Robert Devereux, 2nd Earl of Essex, when he fatally attempted a coup against the younger Cecil.
