About 450,000 Palestinian refugees live in Lebanon today. With the arrival of over one million Syrian refugees in Lebanon since the Syrian civil war started in 2011, Palestinians were no longer the largest refugee group in Lebanon, and many newcomers settled in Palestinian refugee camps. Previous research has considered how recipient societies relate to refugees; this study analyzes intergroup competition and conflict among refugees from different countries by analyzing Palestinians’ perceptions of refugee camp life and attitudes toward Syrian refugees. Focus group interviews were conducted in the largest camp in Lebanon, Ein El Hilweh. Respondents experienced relative deprivation due to the influx of Syrian refugees, who were accused of taking Palestinian jobs and increasing poverty. Respondents complained of increasing violence and social problems (e.g. radicalization and drug use) due to the demographic changes. Especially women experienced that their freedom of movement had become limited in the camp but found it difficult the consider migration. Increasing desperation had also weakened Palestinian resistance identity and trust in resistance organizations.
