It depends on what cultural aspect you are looking at. Halloween (as it is known in America) has drawn inspirations from cultures such as the Celts (Irish), Spanish / Spanish-related countries, and the Paegans.
Halloween can be traced back to the Celts and their ancient festival of Samhain.

Halloween was brought to North America primarily by Irish immigrants in the 19th century. They brought with them the traditions of Samhain, a Celtic festival marking the end of the harvest season, which included customs such as dressing in costumes and carving pumpkins. The celebration evolved over time, influenced by various cultural practices, eventually leading to the modern Halloween we know today.
When you discount the Jews, you are discounting the overwhelming cultural diversity that the Jews brought to Israel as a collective. (It would be like saying "Aside from the Whites, what racial group mostly influenced the culture of the USA?). However, the answer is that the Palestinian Arabs were the ethnic group that influenced the culture of Israel most strongly.
