Abstract: With the emergence of ideological vacuum after the disintegration of the former Soviet Union,Hizbut-Tahrir began to revive in the Central Asia of the former Soviet Union,and has the momentum into the Central Asia. The most obvious features of the activities of Hizbut-Tahrir in the Central Asia are the anti-government and separatist activities in the field of ideology spread by religious extremist ideology. There are many complex reasons for the rise of the Hizbut-Tahrir in the Central Asia. Such as,the ideological vacuum after the collapse of the former USSR and harsh economic conditions provided the space and infrastructure for the emergence of Hizbut-Tahrir in the area;the share with power imbalances is a certain relationship;what's more,the relative deprivation theory,resource mobilization theory and social mobilization theory are very vital factors. In a word,given the current situation for the Hizbut-Tahrir,it is necessary for the Central Asian countries to do a full range of trade-offs in the aspects about political,economic,legal,etc. And they can safeguard the national and social stability,and prevent the politicization of religion.
