It must be said that the wife of the new Grand Duke was not enthusiastic. Until then, she had been having quite a jolly time between their home in Vienna and a sporting estate in the Black Forest, and after two years she was still writing to a friend that she thought she lacked an important requirement for the job, namely the smallest desire to remain in Moravia, but the couple persevered with some success. Their new country’s good fortune was to be located at a sensitive crossroads of many of the trade routes. This ensured invitations to every Royal fête around the world, as well as cheering offers for their daughters’ hands in marriage, and before very long a Russian grand duchess, an Austrian archduchess and a princess of Borbon-Anjou had all begun life in the airless, cramped nurseries of the hideously uncomfortable palace in the capital of Olomouc, a building not much larger than the dean’s residence in the close at Salisbury and a lot less manageable to run.

Surprisingly, perhaps, Grand Ducal Moravia made it as far as the Jazz Age, but the forces of Stalin, coupled with a swelling resistance to the monarchist solution, proved the undoing of the dynasty. By 1947 it was over and the ex-reigning Moravian family had taken up residence in a five-storey house in Trevor Square, a pleasant enough location and very convenient for Harrods.

But even easy shopping could not revive the spirits of the defeated Grand Duke and in a matter of months he had given up the unequal struggle. It was at this point that his son, having assumed the grand ducal title, the last of his family to do so, and released perhaps by the demise of his august papa, made a spirited decision that would vastly diminish his chances of regaining the throne of his forebears and vastly increase his chances of living well in the interim. With the dignified, if pained, acceptance of his widowed mother, a princess of a cadet branch of the Hohenzollerns, he contracted to marry the only daughter of a businessman from Leeds, one Harold Swindley, who had made a fortune in self-catering, package holidays. In the following three years, two children had arrived to bless this most sensible of unions, the new, so-called Crown Prince Feodor and his sister, the Princess Dagmar.

But for us, and even more for our parents, the Fall of the House of Moravia was still pretty recent and even the elevation of Miss Marion Swindley could not dim the lustre of a genuine crown. Only twenty years had passed since their deposition when Dagmar arrived at our parties. Besides, the Communist regime that replaced them was not popular, the family was still on the guest list at Buckingham Palace and there was talk at the time of a restoration coming in Spain. In short, forty years ago the Royalist cause didn’t seem hopeless by any means.

The new Grand Duchess had delivered. The Swindley money may not have been particularly fragrant but, for the first years of the marriage at least, there was quite a lot of it. And she learned her part pretty well until, like every fervent convert, she was soon plus Catholique que le Pape. Admittedly, she was not by any standards a beauty but, as the Dowager Grand Duchess was once heard to sigh when watching her daughter-in-law stump across a drawing room looking like a Marine in training, ‘Oh, well. One can’t have everything,’ and nobody could say she was not impressive. Her size alone guaranteed that. Nor was she a fool, having inherited more from her (discreetly invisible) father than she might care to admit in terms of solid, common sense.

For all the bowing and ma’am’ing that still went on in those days, the Grand Duchess understood that no throne awaited her timid daughter in the post-war world. She also knew that she had not anticipated the drain on her capital made by a husband who wished to live en prince but did not intend to do a day’s work, nor earn a single penny. She was, at heart, a sound northern lass and well aware that no fortune can hope to survive when the expenses are limitless and the income nil, and she was anxious to see the girl settled as well as might be, before the gilt had quite gone off the gingerbread. So she decided that, even though British princesses by that stage never ‘came out’ in any normal way and only occasionally appeared at the parties of special friends, nevertheless Dagmar would participate fully in the whole year-long business. The girl would thereby build a position for herself in British Society and, with any luck, land one of its prizes. The Grand Duchess also accepted – unlike many, if not most, Royals – that she would have to put her hand in her pocket to achieve this. By 1968, when the Grand Duke had been spending like a sailor for a quarter of a century, this could not have been as easy as it was once, but she had bitten off the mouthful and she fully intended to chew it. I am happy to say I was on the list to be invited.

The inspiration for the party was the Duchess of Richmond’s Ball, that famous 1815 gathering, given in Brussels on the very eve of Waterloo, and it was held at the Dorchester in Park Lane. Today, one thinks of the hotel as the haunt of film stars and merchants from the East, but in those days it played quite a major part in what was still referred to as ‘Society.’ On the night in question we came in, I think, by the ballroom entrance at the side, situated on Park Lane itself, and the theme of the evening was quite clear the moment one stepped inside, into that long, rather low, hall. Liveried footmen stood to attention, all modern signs, ‘Exit’ and the like, had been hidden behind greenery and there were candles everywhere. None of these last details would be legal today, of course, but nobody cared then. In truth, the party seemed to have taken over most of the ground floor of the hotel. It can’t have, really, can it? But that’s what it felt like on the night. Of course, we didn’t arrive much before eleven, having eaten our dinners elsewhere, and the champagne that greeted us, held out by the whitewigged flunkeys, was not by any means the first drink of the evening. One has to remember that in the late 1960s, while nobody suggested that it was a good idea to drive a car when plastered, it was still long before such considerations had begun to shape our social life. ‘Which of you is drinking tonight?’ would have bewildered the couple arriving at a dinner, since the answer would invariably have been ‘both.’ For this reason no hostess scrupled to ask various friends to provide dinners for her guests before a ball.

Later in the Season, when more dances were given in the country, this would entail putting them up for the night, and essentially meant throwing a house party for strangers, who would drunkenly rattle around the countryside in their cars at all hours. But in London the thing was more easily managed. Sometimes you were flattered to receive an invitation to join the dinner provided by the parents of the deb of the evening, but this didn’t happen (to me, anyway) all that often and usually a pleasant little postcard would drop through the letter box, saying that the writer believed you were going to the dance being given for So-and-So and she would be ‘terribly pleased if you would dine here first.’ At the end of which dinner, fairly far gone or at least merry, we would cheerfully climb into our vehicles and head off for the location of the party proper. This system had obvious advantages. The bonus for the young was that the dances went on forever, because they didn’t really get going much before eleven. While the benefit for the old was plain economy. The parents of the girl in question usually had to hire the place, at least in London, and even in the country marquees would be expected unless the house was vast. Then there was the music, as well as a pretty good breakfast at the end of the event, but by adopting this system the hosts were spared the additional burden of dinner and wines for three or four hundred young and hungry people. No wonder the custom cheered the fathers up no end.
