Катаиб
Chader was the vice chairman of the Kataeb Party. He had won the Armenian Catholic seat in the 1951 parliamentary election. As the Kataeb Party had suffered a backlash in the 1951 election, it only fielded two candidates in 1953, Chader and Maurice Gemayel in Beirut II (Achrafieh-Rmeil-Saifi). Chader had the support from a large part of the Jewish community, which tended to support the Kataeb Party.
