Prince Phillip was royal in his own right. But the husband of an English queen has never been called King. IDK why but IIRC there has only been 3 queens: Elizabeth 1 & 2 & Lady Jane Grey. QEI wasn't married & Jane was queen for 9 days so I guess there wasn't the opportunity to create a precedent.
There have been more than 3.
Mary 1, Elizabeth's sister was Queen in her own right, married King Philip of Spain who was King of Spain. Technically, he was King of England, but his powers in England were much curtailed, and he didn't spend much time in England. He and Mary had no children. Then
Elizabeth l , unmarried.
Jane preceded Mary and is on record as refusing to make her husband king, although she said she would make him a Duke. As it turned out she had no time to do either.
Then with the Stuarts
Mary ll, who along with her husband William overthrew her father James ll and claimed the throne. They reigned jointly as William lll and Mary ll. No children, and he reigned alone after her early death- he was next-but-one in line to the throne anyway, being her first cousin. Next was
Anne, who was married to George of Denmark, who was not king, but remained a Prince. No surviving children- despite 17 (!) pregnancies.
Victoria, of course, had Albert, who was made Prince Consort, a title designed to be the title for a Queen's husband, although it has not officially been granted again (Philip was made a Duke instead).
So 7 Queens regnant (including the disputed Jane). 8 if you count
Matilda back in the twelfth century, but her claim was disputed by her cousin Stephen- although her son eventually became Henry ll, from whom all subsequent monarchs descend.
