How did nationalism play a role in the creation of Israel?

Nationalist Zionism emerged from the Revisionist Zionists, which left the World Zionist Organization in 1935, when the larger group refused to focus on the creation of the Jewish state of Israel as a primary goal of Zionism. Later, the Revisionists evolved into the Likud Party in Israel, which has controlled most Israeli governments since 1977.

Smith and John Hutchinson, elements of Israel’s nationalism and national identity are analyzed as contributing to its existence as a ‘zone of conflict’ and to its violent behavior.

after the roman empire, the catholic church began to unify by taking on many duties of a government.
