In Central Asia, the party has expanded since the breakup of the Soviet Union in the early 1990s from a small group to "one of the most powerful organizations" operating in Central Asia. The region itself has been called "the primary battleground" for the party. Uzbekistan is "the hub" of Hizb ut-Tahrir's activities in Central Asia, while its "headquarters" is now reportedly in Kyrgyzstan. Estimates of the party's size in Central Asia range from 15,000 to 100,000.
