Ambrose Victor Martin (variably "Ambrosio" in Spanish or "Ambrosi" in Catalan) was an Irish-Argentinian known largely for his Irish republican activism in Argentina and Spain. Early life Ambrose Martin was born in the province of Buenos Aires, Argentina in 1900 to an Irish-Argentinian family from County Westmeath. Martin was raised in the small town of Suipacha alongside many other Argentinians of Irish descent. It was probably also during this time that he became acquainted with the many Basque-Argentinians who lived in Suipacha as well, as he would go on to become deeply involved in the Basque nationalist movement both in Spain and Latin America later in his life. In 1914, he was sent off to Mullingar, Ireland to attend St. Finian's College, where he would spend the remainder of his childhood. Early involvement in politics Following the 1916 Easter Rising, the young Ambrose Martin was swept up in the revolutionary fervour and became involved in Sinn Féin. Martin rose within the ranks of the movement, coming to be known as a vibrant orator, and becoming acquainted with notable figures such as Laurence Ginnell, Eamon Bulfin, and Margaret Mary Pearse. He was arrested by the British authorities in 1919 and deported back to Argentina. In Argentina, Ambrose Martin busily worked with Irish republicans to propagandize and raise funds for the movement back in Ireland. He was even apparently implicated in an attempt to organize an IRA brigade in Argentina. Martin was involved with a faction of the Irish-Argentinian community headed by Patrick McManus, a staunch republican from County Donegal whose hardline politics caused annoyance to the small cadre of diplomats sent over from Dublin. After two years, Martin began to journey back to Ireland in 1922 after the pronouncement of the Anglo-Irish Treaty brought an end to the Irish War of Independence. On his way to Ireland, he made a stop in the Basque Country, where he was scheduled to give a series of lectures on Ireland to the youth group of the Basque Nationalist Party. Martin claimed to have 'old friends' from the area, likely going back to his early years in rural Buenos Aires. He made a great impression on the young Basque nationalists, whose press organ reported that "never before have we seen our patriotic youth as impassioned". Martin also gave an inaugural speech on Cumann na mBan for the Basque nationalist women's group Emakume Abertzale Batza ("Association
