From the moment the women with the herbs – following the old custom of strewing them along the route the King would take – appeared, all the spectators knew that with George IV as the central actor the play was going to be a grand one.

Of course he looked splendid; of course he looked all that a King should look; and of course his coronation was a superb glittering colourful spectacle.

But the Queen had made up her mind to share it. She had no sense of propriety, no decorum; she was all that the King was not; but one thing they shared and that was determination: his that she should not share in the coronation, hers that she should.

While the King was making his way from the Speaker’s House to the Abbey the Queen left Brandenburg House for the same destination.

She did not notice that the cheers for her were less fervent than usual. She had believed that when she rode out the crowd would follow her to the Abbey and force an entrance with her, if need be. But she did not know the English. They reviled the King; he was an old roué; he had behaved badly to Mrs Fitzherbert; his debts were enormous; he lived in extravagant splendour while there was great poverty in the country. But this was his coronation and he was playing his part with a flair that they admired. He might be an indifferent ruler; but he was a superb actor and today’s affair was a pageant. They were not going to have it spoilt, and the Queen was wrong to try and force herself where she was not wanted.

That was the verdict of most of the crowd. They were not looking for trouble today, but spectacle. They had come to cheer the King not to boo him. Whoever heard of a king being booed during his coronation when they were all going to get drunk in the taverns shortly drinking his health.

So Caroline rode through silent streets to present herself at the Abbey and be refused admittance – on orders of His Majesty. Nothing deterred she presented herself at another door, only to be once more prevented from entering.

In her tawdry finery she looked vulgar, decided the people. How different from their glorious King who at this moment, under the canopy of State, was receiving the orb and sceptre.

‘Go home,’ shouted a voice; and others took up the strain.

Caroline was bewildered. It was the first time she had received such treatment from the people.

She could not storm the Abbey; she would only wait disconsolate; and at last she gave the order to drive her back to Brandenburg House.

The King was pleased with his people and they were not ill-pleased with him. Today they had not failed him but had helped to drive the wretched Caroline away from the Abbey.

He was benign and regal and his charm was touching said all who beheld it. He presided with kingly dignity over the coronation banquet and when the long exhausting day was over he was cheered on his way to Carlton House.

The cheers of his people were the sweetest music in his ears.

He would have a portrait painted of himself in his coronation garments; it would serve to remind him of this triumphant day.

King George IV! An old man, he thought; and who is there to follow me but Frederick who is even more ill than I and may not live much longer; or William who is getting old, too; and then that precocious infant at Kensington Palace. But he should not misjudge the child; it was the mother who irritated him, not the little girl.

But who knew, there might be someone to displace her yet. Adelaide might bear a child. He himself might become the father of one if he could rid himself of that woman.

But what was he thinking of? He was too old now. He did not want to go through the ridiculous farce of marriage, even if he could … and then find he could not get a child.

He was content with dear, delightful, not exactly intellectual, Lady Conyngham with her beautiful motherly bosom and her handsome looks. She reminded him very often of Maria – but without Maria’s temper.

Ah Maria, he thought, what are you thinking on this day?

He could not know. And did it matter?

He was tired; he wished to rest. He would send for them to get him to bed.

It had been an exhausting day.

The King decided a few days after his coronation that he would visit different parts of his realm so that he might have the experience of speaking personally with his subjects. His intention was to go first to Ireland, and preparations were immediately begun.

People continued to discuss the coronation, the splendour of which would be talked of for months to come; those who had not witnessed it listened to accounts of it in the taverns and wherever people congregated. The manager of Drury Lane decided that instead of a new play he would put on the Pageant of the Coronation which should be like the real thing in every detail.

It seemed to be an excellent idea and when the curtain rose on the Abbey scene there was a hushed silence in the house and everyone joined in the ceremony, cheering and calling God Save the King.

No play could succeed as this spectacle did, and the theatre was crowded night after night.

The Queen heard of what was going on and thought that if she attended no one would be able to ignore her this time.

So she dressed herself in odd vulgar clothes – too short in the skirt, too low in the neck, with the feather and diamond headdress waving over her wig – and appeared in the royal box.

She had been ill for some time, refusing to be treated by doctors and successfully hiding her affliction, dosing herself with laudanum which brought her the solace of sleep; but as the time had gone on she had found it necessary to increase the doses and thus caused alarm to some of her ladies. They had found it useless to dissuade her. She had to give herself relief from pain; she had to be able to feel alive – and mischievous again; she had to paint her face more brightly with rouge and plaster it with white lead to get the startling contrast.

She would laugh as she did so and say to her most intimate lady-in-waiting, ‘Now my love, what would they think of me if they saw me without my warpaint, eh? They’d think I’d come from the grave instead of from Brandenburg House. We don’t want to give the good people a shock or His High and Mighty Majesty so much pleasure, do we?’

They, who knew how ill she was, were anxious for her. In her way she had been a good mistress. Kind, friendly – in fact over-familiar calling them ‘my love’ and ‘my dear’ in front of the lower servants. But if they were in trouble she would be the first to help; and in spite of her eccentricities, which at times seemed to border on insanity, they were fond of her.

Painted and glittering with jewels, the plumes waving in her hair, she set out for Drury Lane.

She was going to win back the popularity she had lost. The King had won the battle of the coronation; it was after all his coronation, though she ought to have shared it with him; but he was their King and she but the Queen Consort. She granted that. It was for this reason that the people had been lukewarm to her; it was because he was after all the King that they had not forced an entrance for her into the Abbey.

Never mind. The coronation was over. Now they would be sorry for her. The first skirmish would be in the Drury Lane where they would cheer her and feel it was a shame that a queen had to witness a mock coronation from a box in a theatre when she had been excluded from her own in the Abbey.

When she entered the theatre the people rose and cheered her. Grinning wildly, bowing so vigorously that the feathers were in danger of being dislodged, she responded to the greeting and the pageant began. Before it was half way through, the effects of the mild dose of laudanum she had taken to enable her to visit the theatre began to decline, and her lady-in-waiting looked at her in some alarm.

‘I think … I should leave the box … for a moment,’ she said faintly.

She sent one of her attendants to tell the manager not to interrupt the show simply because she wished to slip out for a few moments.

So she left the box while the stage coronation continued; and after more sips of the laudanum she was able to return. But not all the artificial colour on her face could disguise the fact that she was ill.

As the audience sang the national anthem, glancing up at her box, she bowed but was forced to grip the front of the box as she did so.

Wildly they cheered her, and she tried to respond; but she could only murmur: ‘Get me to the carriage.’

‘The Queen is ill,’ it was whispered. ‘The trouble has been too much for her.’

She was led out to her carriage and was swiftly driven home. Her ladies took off the clothes that were always too tight for her gross body; they lifted off her wig; they removed the rouge and lead from her face and revealed a tired old woman with the marks of a ravaging disease clearly defined.

Lying in her bed she said in an almost jaunty way: ‘Something tells me I shall never get up again.’

The King on his way to Ireland for the first State visit of his reign was aboard the royal yacht at Holyhead when the news was brought to him.

The Queen had died less than a fortnight after that visit to the theatre.

Free! he thought. At last! For twenty-six years he had been bound to that loathsome creature and now he was free! Never again would she have the power to plague him. Never again need he wonder what she would do next.

He stood on the deck of the Royal Sovereign and savoured the breezes from the sea.

For years he had been in the thrall of his father and almost immediately he had been tied to that woman. This was his first real taste of freedom. He was King, the ruler of his country, and best of all he was a free man. No longer need he be tormented by the most vulgar woman in the world to whom ironically he, the most exquisite gentleman, had been married.
