Nationalism in 19th century

What role did nationalism play in 19th century Palestine?

During 19th century, Jews brought up the issue that the Palestine belongs to them. The reason is because they lived in the country, and they thought that god told them to regain Palestine because they lost it. When Jews were gathered, nationalism played a important role in them. They could believe and trust each other, so that they could get to the same goal.
However, during the class, I learned that the nationalsim also play a role in fleeing from Ottomon Empire, and autonomy/independent. Also, nationalism played role in Arab. with autonomy, and fleeing from compression.
