What is the difference between Arab nationalism and and Zionism?

 Arab Nationalism is a political ideology that rose prominently in the 20th century, advocating for the unification of Arab people into a single nation or state, based on shared language, culture, history, and sometimes religion (although it's more about cultural identity than strictly religious ). It seeks to foster a sense of solidarity among Arabs across different countries, often in opposition to colonialism, Western influence, and sometimes against the establishment of non-Arab states within historically Arab territories.

Zionism , on the other hand, is the nationalist movement of the Jewish people that supports the re-establishment of, and the right to, a Jewish homeland in the territory defined as the historic Land of Israel (now largely corresponding to the State of Israel ). Zionism began in the late 19th century as a response to anti-Semitism in Europe and the desire for a national home where Jews could be a majority and govern themselves. While Zionism focuses on Jewish self-determination in Israel, Arab nationalism focuses on the political and cultural unity of the Arab world, often seeing Zionism as antithetical to its goals due to the creation of Israel in what was previously part of the Ottoman Empire and British Mandate Palestine.
