The Caspian tiger, also known as the Persian tiger, Turanian tiger, Mazandaran tiger  or Hyrcanian tiger,   was the westernmost population of Siberian tiger, found in Iran, Iraq, Afghanistan, Turkey, Mongolia, Kazakhstan, Caucasus, Tajikistan, Turkmenistan, and Uzbekistan until it apparently became extinct in the late 1950s, though there have been several alleged sightings of the tiger.

 

The Caspian tiger's body was generally less massive than that of its Far Eastern cousins, and its average size slightly less. In Turkestan, male tigers exceeded 200 cm in length, though an estimated body length of 270 cm was recorded. The maximum known weight was 240 kg.

 

The Russian government had worked hard to eradicate the Caspian tiger during the planning of a huge land reclamation program in the beginning of the 20th century. They felt that there was no room for the tiger in their plans and so they instructed the Russian army to exterminate all of the tigers found around the areas of the Caspian Sea and Central Asia, a project that was carried out very efficiently. Once the extermination of the Caspian tiger was almost complete, the farmers cleared forests and planted crops, such as rice and cotton.
