A global existence theorem with large initial data in L{sup 1} is given for the modified Enskog equation in R{sup 3}. The method, which is based on the existence of a Liapunov functional (analog of the H-Boltzmann theorem), utilizes a weak compactness argument in L{sup 1} in a similar way to the DiPerna-Lions proof for the Boltzmann equation. The existence theorem is obtained under certain condition on the behavior of the geometric factor Y. The condition on Y amounts to the fact that the L{sup 1} norm of the collision term grows linearly when the local density tends to infinity.
