Final answer:
Jordan is the country with the largest number of Palestinian refugees, who have been largely integrated into Jordanian society with the offer of citizenship. Jordan also hosts refugees from other regional conflicts, illustrating its key role in refugee assistance.
Step-by-step explanation:
The largest number of Palestinian refugees reside in Jordan. After the creation of the Jewish State of Israel in 1948, a significant number of Palestinians were displaced and became refugees. By 1950, over 750,000 Palestinians had been forced out of their homes. The United Nations has reported that Jordan hosts the highest number of Palestinian refugees, with the country granting most of them Jordanian citizenship. Refugees are a substantial part of Jordan's population, which also includes refugees from the US war in Iraq. Additionally, Jordan has historically skillfully managed its relations with neighboring Israel and has provided shelter for refugees from various regional conflicts.
The Za'atari refugee camp in Jordan is an example of a large camp settlement for Syrian refugees, indicating Jordan's significant role in refugee assistance in the region. The international community has supported initiatives to help refugees in countries like Lebanon, Turkey, and Jordan, acknowledging their efforts in hosting and assisting large numbers of displaced people.
