Cats that were imported from Siam (today, Thailand) to Western countries in the 19th and early 20th century were broader in features than the modern Western Siamese. While the Thai, known in Thailand as the whichianmat (among other, non-standardized spellings, e.g. wichien-maat), has common ancestry with the Western Siamese, generations of separate breeding led to the development of two distinct breeds, which began to bifurcate in the 1950s, with more extreme features dominating the cat show circuit, and thus becoming the dominant variety of Siamese in the West. Starting in the 1980s, various breed clubs in both North America and Europe appeared that were dedicated to preserving the type that represents the early 20th-century Siamese, comparable to those still found in Thailand catteries, and which were shown again beginning in 1993 in Europe. The World Cat Federation (WCF) recognized the old-style as separate breed, Thai, with full championship competitive status, in 1990. The rename was not universally accepted; in 2000, the independent Old-Style Siamese Club (OSSC) formed in the UK to preserve and promote the breed as such.
