After his release from prison in 1978, Adams assumed the vice presidency of Sinn Féin. As early as 1979, he tried to convince his party to give up violence and turn to political action. In 1983, the year he was elected to the House of Commons, he and the northern cadres took control of the republican movement. As the new president of Sinn Féin, Adams ended the party's policy of abstention so that party representatives could be seated in Parliament. A skillful political tactician, Adams has since managed to steer his followers toward a peaceful solution to the Northern Ireland conflict without causing the party to break apart. Although by no means an uncontroversial figure, he is viewed as one of the major engineers of the 1998 Good Friday Agreement.
