The leaders of Israel, mostly European and Russian immigrant Jews, proclaimed a sovereign, independent Israel in 1948. The Arabs who lived in Israel at the time, and who chose to stay there, became full citizens of the country at the same time as everyone else there.
However, there were no non-Jewish Arabs who actively supported the Zionists before the Declaration of Statehood. (Therefore, there were no Arabs on Ben-Gurion's committee that sanctioned the Declaration of Statehood.) Some of the Arabs who chose not to flee during the Jewish-Arab Engagements of 1947-1949 (and Arab Israeli War of 1948-9), like the Sheikh of Abu Ghosh made open pacts with the State of Israel after the Declaration recognizing both its Right to Exist and their allegiance to its vision of Jewish Democracy. Other Sheikhs who stayed openly contributed to the Israeli War Effort during this period either with supplies or (much more rarely) manpower.
