When did albino tigers become endangered?

Albino tigers, often referred to as white tigers, are not a separate subspecies but rather a genetic variation of the Bengal tiger. They became increasingly endangered in the mid-20th century due to habitat loss, poaching, and the practice of inbreeding to produce white tigers for zoos and entertainment. By the 1990s, their population declined significantly, leading to heightened conservation efforts. Today, while some white tigers exist in captivity, they are still considered endangered due to the overall decline of their natural habitats and the complexities of their breeding.
