In this thesis, we proposed two new distributions; Firstly, wrapped Sujatha distribution and wrapped Sushila distribution which are studied. We derived for both new circular distributions the probability density function, the cumulative distribution function, the reliability and hazard rate functions are computed. In addition, the means, skewness, and kurtosis are obtained. The invariance properties of the distribution are investigated, invariance under change of initial direction, and the reference system orientation. The maximum likelihood method is employed to estimate the distribution parameters and simulations are carried out to investigate the performance of the maximum likelihood estimator
