He served only one term, during which he started the process to give the vote to Cuban women (resolution in the Senate, 1921), negotiated the return of Cuban sovereignty over the Isle of Pines (Isla de la Juventud, 110.86 square kilometers) which had been occupied by the U.S. since 1898 (Hay-Quedada Treaty of 1925), obtained a $50 million USD loan from J.P. Morgan, and for the first time allowed full freedom of expression and of the press. On 10 October 1922 he launched PWX, the first Cuban radio station.
