The British Longhair is a longer-haired development from the longstanding British Shorthair breed. In the mid- 20th century, British Shorthairs were interbred with imported long-haired varieties, like the Turkish Angora and what today is called the Traditional Persian, with an aim to producing more stout and round-faced stock, while retaining the short coat. As a result of this hybridization, British catteries have frequently produced (generally unwanted) semi-long-haired specimens among their litters. In more recent years, these have been intentionally bred (often outside the UK) to each other and sometimes to standard British Shorthairs, to establish a consistent, formalized British Longhair breed.
The breed is in the first stages of recognition with the two major cat fancy organizations in the UK, the Governing Council of the Cat Fancy and Felis Britannica (the UK branch of Fédération Internationale Féline). The naming of the breed, and whether it is treated as a distinct breed, is quite inconsistent between the few pedigree registry organisations that acknowledge it as of 2015. It is called the British Longhair, British Longhair Variant, British Semi-Longhair, and Longhair British. It is sometimes known as the Britannica in some European countries, and also the Lowlander in the United States.Feline Federation Europe (FFE) calls them (in the same breed standard), the British Longhair Variant, the Highlander, and the Highland Straight. However, the latter two of those names have already been used by other registries to refer to completely different cats.
