This study argues that the process of re-Islamization has accelerated in the aftermath of 9/11 as an increasing number of adolescents and young adults (daughters of immigrant Muslims) are assuming a public Islamic identity by wearing the hijab (headscarf). Drawing on two decades of research on American Muslim communities and in-depth interviews with American Muslim youth, this study finds that the hijab has become a symbol of an American Islamic identity—a public affirmation of trust in the American system that guarantees freedom of religion and speech. At the same time, it has also become a symbol of anti-colonial solidarity and resistance to efforts to eradicate Islam in an American environment that is increasingly seen as anti-Islamic. Implications for the future role of the veil in the lives of American Muslims are discussed
