Robert Dudley is made Earl of Leicester - 29 September 1564 - The Tudor Society

On September 29, 1564, Robert Dudley was made the Earl of Leicester. From the article:

"On this day in history, 29th September 1564, Robert Dudley was made Earl of Leicester, an earldom which had been planned earlier in the year to make him more acceptable as a bridegroom to Mary, Queen of Scots. This earldom was an important one, having previously been held by royal princes like John of Gaunt and Henry of Bolingbroke (Henry IV). Although Dudley behaved impeccably at the ceremony, the queen did not. As she put the chain of earldom around Dudley's neck, she "could not refrain from putting her hand in his neck to kittle him smilingly." A loving gesture and perhaps one that was meant to reassure Dudley that he was still hers.

When Elizabeth first spoke to William Maitland of Lethington, the Scottish ambassador, about the potential marriage match, he laughed it off and then asked why Elizabeth herself did not marry Dudley; that way she could leave both her husband and kingdom to Mary, Queen of Scots! Elizabeth's chief advisor, William Cecil, supported the plan. After all, it killed two birds with one stone: it got rid of the troublesome Dudley and it formed an alliance with Scotland. Cecil wrote to Maitland in praise of Dudley but Maitland did not pass on the proposal to his queen because Dudley was not even a peer. He was a nobody. This was something that Elizabeth said that she would rectify by giving Dudley an earldom. However, although Elizabeth's ambassador to Scotland, Thomas Randolph, was ordered to keep on urging the Scottish queen to marry Dudley, neither Mary, Queen of Scots or Robert Dudley were keen on the idea.

In the spring of 1564, when Randolph spoke to Mary of the idea, she was flabbergasted. She had been married to the King of France, and here was Elizabeth trying to marry her off to a nobody. She did not say an outright "no", and demanded that if she were to marry Dudley then she should be named Elizabeth’s heir, but this was something that Elizabeth would never consider.

The marriage never took place, and it is hard to know how serious Elizabeth was in her offer of Dudley, her favourite, to her nemesis, Mary, Queen of Scots."
