The secondary anisotropies and polarization of the Cosmic Microwave Background (CMB) provide a laboratory for the study of the epoch of reionization in the Universe. Here, we concentrate on the CMB polarization in models with inhomogeneous reionization. Although the amplitude of the polarization anisotropy is estimated to be much smaller than that in the temperature, it is advantageous to consider the polarization signal since it is generated when photons and electrons scatter for the last time. Detection of these signals will place important constraints on the reionization history of the Universe.
