In 1910, the Mokarzel brothers decided to adapt the linotype machine to Arabic script to mitigate the expensive cost and tedious task of manual typesetting. Naoum Mokarzel imported Arabic type letters from Egypt and acquired the first such machine for "Al-Hoda" from the Mergenthaler company. While the linotype machine made printing cheaper, there was significant competition for readership since New York's Arabic-speaking community did not exceed 10,000 before World War II. Through his writing in "Al-Hoda" and other American journals, Mokarzel was gaining further prominence as a leading figure of the American Maronite community and was seeking a similarly prominent woman to marry. In 1910 he married for the third and last time; his wife, Rose Abillama hailed from a princely Maronite family and was more than twenty years his minor. Mokarzel did not have any offspring from any of his marriages. In 1911, Mokarzel became the permanent president of the Lebanon League of Progress (Jamʿiyyat al-Nahda al-Lubnaniyya) a Maronite organization established in the US by Ibrahim Najjar dedicated to promote a French-supported Maronite protectorate in Lebanon. In June 1913, Mokarzel was the Lebanon League of Progress delegate to the First Arab Congress in Paris where he represented the North American Maronites. Delegates to the congress discussed reforms to grant the Arabs living under the Ottoman Empire autonomy. The congress did not have a lasting effect, due mostly to the beginning of World War I. In 1917, Mokarzel sought and collected through "Al-Hoda" more than $30,000 US in donations to relieve his compatriots in Mount Lebanon who were experiencing a great famine due to Entente and Ottoman blockades. The collected donations were to be personally dispensed by Mokarzel, but half of the money was directed to fund a volunteer armed force that was gathering to enter Lebanon instead of toward relief aid. Mokarzel incorrectly surmised that the Entente powers would come to the Maronite force's assistance, but they did not take interest in the armed venture. Mokarzel represented the Lebanon League of Progress in the Paris Peace Conference of 1919 where he advocated French tutelage over Mount Lebanon. On September 28, 1919, when the prospects of French control began to materialize, Mokarzel dispatched a fervent telegram to his New York office announcing that the French army would replace the British forces in Greater Syria and that Lebanon would come under French guardianship.
