There were no queens in foreign countries at that time
In European history, whether it was ancient Greece, ancient Rome, or the age of knights in the Middle Ages, the terms emperor and king were always reserved for men. Only the Eastern Roman Empire produced a few female emperors who had little influence. But starting from the 14th century, in one country after another, queens (emperors) appeared intermittently one after another. Until the present day, there have been a total of about thirty. 6 from the UK, 4 from Russia, 3 from the Netherlands, 2 from Luxembourg, 3 from Spain, 2 from Portugal, 2 from Sweden, 2 from Denmark, 1 from Austria, 1 from Poland, 1 from Hungary, as well as Scotland and Nava. Countries that have been annexed by others, such as Latvia and Naples, have also produced queens.
